How to send headers from controller into another class in Java

How to send headers from controller into another class in Java - java

I have a controller like below
SubmitBatchController.java
#RestController
#RequestMapping({"/"})
#Api(value = "batch", tags = {"Batch "}, authorizations = {#Authorization(value="JwtToken")})
public class SubmitBatchController extends BasicController {
#PostMapping(value = "v1/batch", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
#ResponseBody
public CommonResponse<BatchSubmissionResponseModel> submitBatchClaim(
#ApiParam(hidden = true) #RequestHeader(required = false) String transId,
#ApiParam(hidden = true) #RequestHeader(required = false) String paymentReleaseInd,
#ApiParam(hidden = true) #RequestHeader(required = false) String emailMatchedInd,
#ApiParam(hidden = true) #RequestHeader(vrequired = false) String role,
#RequestBody BatchSubmissionRequestModel batchSubmissionRequestModel,
BindingResult br, HttpServletRequest request, HttpServletResponse response) throws Exception {
LocalDateTime startLocaleDateTime = LocalDateTime.now();
BatchSubmissionResponseModel batchSubmissionResponseModel = new BatchSubmissionResponseModel();
ContextBase ctxBase = getChainBaseContext(request);
ctxBase.put(PARAM_LOC.RESPONSE, batchSubmissionResponseModel);
HeaderRequestModel headers = new headerRequestModel();
batchSubmissionRequestModel.setTransId(transId);
headers.setRole(role);
headers.setPaymentReleaseInd(paymentReleaseInd);
headers.setEmailMatchedInd(emailMatchedInd);
batchSubmissionRequestModel.setHeaderRequestModel(headers);
}
}
BatchSubmissionRequestModel.java
public class BatchSubmissionRequestModel {
#ApiModelProperty(hidden = true) // this is captured as a header and set in the controller
#NotBlank(message = "Headers.transId.NotBlank")
private String transId;
#ApiModelProperty(hidden = true)
private HeaderRequestModel headerRequestModel;
public String getTransId() {
return transId;
}
public void setTransId(String transId) {
this.transId = transId;
}
public HeaderRequestModel getHeaderRequestModel() {
return headerRequestModel;
}
public void setHeaderRequestModel(HeaderRequestModel headerRequestModel) {
this.headerRequestModel= headerRequestModel;
}
}
HeaderRequestModel.java
public class HeaderRequestModel {
private String paymentReleaseInd;
private String emailMatchedInd;
private String role;
public String getPaymentReleaseInd() {
return paymentReleaseInd;
}
public void setPaymentReleaseInd(String paymentReleaseInd) {
this.paymentReleaseInd = paymentReleaseInd;
}
public String getEmailMatchedInd() {
return emailMatchedInd;
}
public void setEmailMatchedInd(String emailMatchedInd) {
this.emailMatchedInd = emailMatchedInd;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
}
Now I have another class, which has to take the headers from SubmitBatchController.java & set it into FullEligibilityService.java
FullEligibilityRequestModel.java
public class FullEligibilityRequestModel{
private String transId;
private HeaderRequestModel headerRequestModel;
public String getTransId() {
return transId;
}
public void setTransId(String transId) {
this.transId = transId;
}
public DapHeaderRequestModel getDapHeaderRequestModel() {
return dapHeaderRequestModel;
}
public void setDapHeaderRequestModel(DapHeaderRequestModel dapHeaderRequestModel) {
this.dapHeaderRequestModel = dapHeaderRequestModel;
}
}
FullEligibilityService.java
(request is mapped to FullEligibilityRequestModel)
#Service
#Scope(BeanDefinition.SCOPE_PROTOTYPE)
public class FullEligibilityServiceextends extends AServiceTask <FullEligibilityRequestModel, FullEligibilityResponseModel>{
private static final String HEADER_FULL_ELIGIBILITY_TRANS_ID = "transId";
private static final String HEADER_PAYMENT_RELEASE_INDICAATOR = "paymentReleaseInd";
private static final String HEADER_EMAIL_MATCHED_INDICATOR = "emailMatchedInd";
private static final String HEADER_ROLE = "role";
#Override
protected void processTask() {
try {
Map<String, String> headers = new HashMap<String, String>();
headers.put(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE);
headers.put(HEADER_FULL_ELIGIBILITY_TRANS_ID, request.getTransId());
headers.put(HEADER_PAYMENT_RELEASE_INDICAATOR, request.getHeaderRequestModel().getPaymentReleaseInd()); // getting NULL
headers.put(HEADER_EMAIL_MATCHED_INDICATOR, request.getHeaderRequestModel().getEmailMatchedInd()); // getting NULL
headers.put(HEADER_DAP_ROLE, request.getHeaderRequestModel().getRole()); // getting NULL
.....
}
catch (Exception e) {
LOGGER.error("FullEligibilityService.processTask call failed");
exception = e;
status = STATUS_TASK_EXCEPTION;
e.printStackTrace();
}
}
I'm not able to get the headers set in SubmitBatchController.java into FullEligibilityService.java, due to which I get null values.
Can someone help me how to set the PaymentReleaseInd, EmailMatchedInd, HeaderRequestModel set in SubmitBatchController.java into FullEligibilityService.java

You need to inject an instance of FullEligibilityService into SubmitBatchController as follows and then you just need to call the corresponding method with the required parameters:
#RestController
#RequestMapping({"/"})
#Api(value = "batch", tags = {"Batch "}, authorizations = {#Authorization(value="JwtToken")})
public class SubmitBatchController extends BasicController {
#Autowired
FullEligibilityService fullEligibilityService;
#PostMapping(value = "v1/batch", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
#ResponseBody
public CommonResponse<BatchSubmissionResponseModel> submitBatchClaim(
#ApiParam(hidden = true) #RequestHeader(required = false) String transId,
#ApiParam(hidden = true) #RequestHeader(required = false) String paymentReleaseInd,
#ApiParam(hidden = true) #RequestHeader(required = false) String emailMatchedInd,
#ApiParam(hidden = true) #RequestHeader(vrequired = false) String role,
#RequestBody BatchSubmissionRequestModel batchSubmissionRequestModel,
BindingResult br, HttpServletRequest request, HttpServletResponse response) throws Exception {
LocalDateTime startLocaleDateTime = LocalDateTime.now();
BatchSubmissionResponseModel batchSubmissionResponseModel = new BatchSubmissionResponseModel();
ContextBase ctxBase = getChainBaseContext(request);
ctxBase.put(PARAM_LOC.RESPONSE, batchSubmissionResponseModel);
HeaderRequestModel headers = new headerRequestModel();
batchSubmissionRequestModel.setTransId(transId);
headers.setRole(role);
headers.setPaymentReleaseInd(paymentReleaseInd);
headers.setEmailMatchedInd(emailMatchedInd);
fullEligibilityService.processTask(paymentReleaseInd, emailMatchedInd, headers);
}
(...)
}
You need to change Service to accept the data you need as follows:
#Service
public class FullEligibilityServiceextends extends AServiceTask <FullEligibilityRequestModel, FullEligibilityResponseModel>{
public void processTask(String paymentReleaseInd, String emailMatchedInd, HeaderRequestModel headers) {
(...) //Whatever logic you want to implement
}
Right now you are trying to pass around the data you need via request headers which is definitely a bad practice.

thenReturn() wants Optional, but test fails

I'm trying to do an Unit test, but I receive the error 'cannot resolve the method thenReturn(suspectTest) ; wrap using java.Optional', but when I do (.thenReturn(Optional.of(suspectTest)), the test fails - 'Optional cannot be cast to class Suspect'.

Spring rest controller not working for file upload

I have tried a rest api without any View with mongodb. My application is working fine with Spring boot embedded server with no error. With standalone tomcat application is running without error but cannot access #RestController mapped url. It shows 404 page not found. It is not creating that url but other url works fine.
Here is config
FileStorageProperties.java
#Component
public class FileStorageProperties {
private static String baseDir = "E://temp//FileManager//";

try {
MediaType mediaType = MediaType.parseMediaType(mineType);
return mediaType;
} catch (Exception e) {
return MediaType.APPLICATION_OCTET_STREAM;
}
}
}
Here is model

Now repository:
AvatarRepository.java
public interface AvatarRepository extends MongoRepository<Avatar, String>{
public Avatar findAvatarByGeneratedName(String generatedName);

}
AvatarRepositopryImpl.java - There are some overrided MongoRepository methods which are ignored on the following code as those are not used at all.

Here is my service:

return avatarRepository.save(avatar);
}
public void deleteAvatarByGeneratedName(String generatedName, Avatar avatar) {

avatarRepository.deleteById(avatar.getId());
}
AvatarManager.java
public class AvatarManager {

#Autowired

public AvatarManager(AvatarService avatarService) {
this.avatarService = avatarService;
}
public String saveAvatar(User user, MultipartFile file) {
deleteAvatarByUser(user);
String[] ext = file.getOriginalFilename().split(Pattern.quote("."));
String generatedName = new UUIDGenerator().generateId(avatar).toString() + "." + ext[ext.length - 1];
avatarService.saveAvatar(user, file.getOriginalFilename(), generatedName, file.getSize() + "");
new FileStorageService(new FileStorageProperties()).uploadFile(file, generatedName);
new UploadFileResponse(generatedName, file.getContentType(), file.getSize());

}
public void deleteAvatar(String generatedName) {
Avatar avatar = avatarService.findAvatarByGeneratedName(generatedName);
if (avatar != null) {

}
}
public void deleteAvatarByUser(User user) {
// System.out.println(user);

// System.out.println(avatar.getGeneratedName());
if (avatar != null) {

}
}
public ResponseEntity<Resource> downloadAvatar(String avatarGeneratedName, HttpServletRequest request) {
// System.out.println(request);
return new FileStorageService(new FileStorageProperties()).downloadFile(avatarGeneratedName, request);
}
}
Now Controller. I am giving two mapping. The first one is not involved with file manager. It works on both server. The another one is working on spring boot embedded server but not on standalone tomcat. It also is not showing any error or create any url.
Here is the Controller.java;
#CrossOrigin(origins = { "*" })
#RestController
public class UserController {
#Autowired
EmployeeService employeeService;
#Autowired
UserService userService;
#Autowired
AvatarService avatarService;
#Autowired
BCryptPasswordEncoder passwordEncoder;
//It works on both server
#RequestMapping(value = "/login", method = RequestMethod.POST)
public String loginEmployee(#RequestParam Map<String, String> data) {
return new EmployeeManager(employeeService, userService)
.validateUserLogin(data.get("0").toString(), data.get("1"), passwordEncoder).toString();
}
//It doesn't work with standalone server
#RequestMapping(value = "/edit-employee-profile", method = RequestMethod.POST)
public void editProfileEmployee(#RequestParam(value = "avatar", required = false) MultipartFile file,
#RequestParam(value = "user") String data) {
JSONParser jp = new JSONParser(data);
System.out.println(jp);
LinkedHashMap<String, Object> userInfo;
try {
userInfo = jp.parseObject();
User user = userService.findUserByEmail(userInfo.get("email").toString());
System.out.println(user);
user.setAvatarExistance(true);
userService.updateUser(user);
// Employee employee = employeeService.findEmployeeByUser(user);
System.out.println(data);
new EmployeeManager(employeeService, userService).employeeProfileEdit(data);
if (file != null) {
System.out.println(file);
new AvatarManager(avatarService).saveAvatar(user, file);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// return "";
}

Post the file as request body (rather than as URL parameter and #RequestParam) to not excced the safe maximum URL length:
#RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
#ResponseStatus(value = HttpStatus.OK)
public void uploadFile(ModelMap m, MultipartHttpServletRequest request) {
MultiValueMap<String, MultipartFile> multiFileMap = request.getMultiFileMap();
List<MultipartFile> files = multiFileMap.isEmpty() ? null : multiFileMap.values().iterator().next();
MultipartFile file = files != null && !files.isEmpty() ? files.get(0) : null;
// ...
}

Spring 4 , REST Service returns a 415 error from Tomcat

I am trying to test the POST method in a REST service with Spring 4. It works fine in my integration tests with MockMvcBuilders.standaloneSetup but I deployed it in a Tomcat 8.5.8 and I can no understand why it is not working. I receive this message:
HTTP Status 415 -
type Status report
message
description The server refused this request because the request entity
is in a format not supported by the requested resource for the
requested method.
________________
but the Tomcat Server receives this request (extracted from wireshark):
POST /app-1.0-SNAPSHOT/v1.0/concentrators/ HTTP/1.1
User-Agent: curl/7.35.0

, "ftpServerIp":"ftpServerIp","numSerie" :"numSerie","idConcentrator":-1,"infoCameras":[]}
It seems fine I don't know where is the mistake.
My REST service is:
#RequestMapping(value = "/", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
public ResponseEntity<String> post(#RequestBody ConfigurationConcentrator configurationConcentrator) {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
try {
configureConcentrator.create(configurationConcentrator);
} catch (IncorrectDBOperation | ErrorSendMessageException e) {
return new ResponseEntity<String>(e.getMessage(), headers, HttpStatus.BAD_REQUEST);
}
return new ResponseEntity<String>(HttpStatus.CREATED);
}
Also, It checked the jackson dependencies (databind, core and annotations) and they are added in .war file.
This is my curl command:
curl -X POST -H "Content-Type: application/json" --data #addConcentrator2.json http://x.x.x.x:8080/app-1.0-SNAPSHOT/v1.0/concentrators/
It seems, It can not resolve correctly which interceptor needs, but I don't see the problem:
#RequestMapping(value = "/{id}", method = RequestMethod.GET, consumes = { "application/json" }, produces = { "application/json" })
public #ResponseBody ResponseEntity<ConfigurationConcentrator> get(#PathVariable("id") String id) {
....
}
#RequestMapping(value = "/", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
public ResponseEntity<String> post(#RequestBody ConfigurationConcentrator configurationConcentrator) {
....
}
#RequestMapping(value = "/{id}", method = RequestMethod.PUT, consumes = { "application/json" }, produces = { "application/json" })
public ResponseEntity<String> put(#PathVariable("id") String id, #RequestBody ConfigurationConcentrator configurationConcentrator) {
....
}
#RequestMapping(value = "/{id}/cameras/{idcamera}", method = RequestMethod.PUT, consumes = { "application/json" }, produces = { "application/json" })
public ResponseEntity<String> putCameras(#PathVariable("id") String id, #PathVariable("idcamera") String idCamera,
....
}
#RequestMapping(value = "/{id}/cameras", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
public ResponseEntity<String> postCameras(#PathVariable("id") String id, #RequestBody List<ConfigurationCamera> configurationCameras) {

}
#RequestMapping(value = "/{id}/initialconfiguration", method = RequestMethod.GET, consumes = { "application/json" }, produces = { "application/json" })
public ResponseEntity<StatusInitialConfiguration> getInitialConfiguration(#PathVariable("id") String numSerie) {
....
}
UPDATE1:
I updated the curl command with the Accept header.
curl -X POST -H "Content-Type: application/json" -H "Accept: application/json" --data #addConcentrator2.json http://x.x.x.x:8080/app-1.0-SNAPSHOT/v1.0/concentrators/

UPDATE4
I simplified the mapped object class , and I receive the same error.
public class DTOConfigurationConcentrator {
private String street;
private String num;
public DTOConfigurationConcentrator() {
super();
}
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
public String getNum() {
return num;
}
public void setNum(String num) {
this.num = num;
}
}
It seems something related to the tool for the json serialization but I don't know exactly how I can check this.

I forgot to tag my configuration class with #EnableWebMvc...

Select JsonView in the Spring MVC Controller

I'm currently writing a REST api using Jackson (2.4.0-rc3) and spring mvc (4.0.3), and I'm trying to make it secure.
In this way, I try to use JsonView to select the parts of the objects that can be serialized.
I've found the solution (which is not for me) to annotate my Controller method with the view I want. But I'd like to select on the fly the view inside the controller.
Is it possible to extend the ResponseEntity class in order to specify which JsonView I want ?
A little piece of code :
Here is the account class
public class Account {
#JsonProperty(value = "account_id")
private Long accountId;
#JsonProperty(value = "mail_address")
private String mailAddress;
#JsonProperty(value = "password")
private String password;
#JsonProperty(value = "insert_event")
private Date insertEvent;
#JsonProperty(value = "update_event")
private Date updateEvent;
#JsonProperty(value = "delete_event")
private Date deleteEvent;
#JsonView(value = PublicView.class)
public Long getAccountId() {
return accountId;
}
#JsonView(value = PublicView.class)
public void setAccountId(Long accountId) {
this.accountId = accountId;
}
#JsonView(value = OwnerView.class)
public String getMailAddress() {
return mailAddress;
}
#JsonView(value = OwnerView.class)
public void setMailAddress(String mailAddress) {
this.mailAddress = mailAddress;
}
#JsonIgnore
public String getPassword() {
return password;
}
#JsonView(value = OwnerView.class)
public void setPassword(String password) {
this.password = password;
}
#JsonView(value = AdminView.class)
public Date getInsertEvent() {
return insertEvent;
}
#JsonView(value = AdminView.class)
public void setInsertEvent(Date insertEvent) {
this.insertEvent = insertEvent;
}
#JsonView(value = AdminView.class)
public Date getUpdateEvent() {
return updateEvent;
}
#JsonView(value = AdminView.class)
public void setUpdateEvent(Date updateEvent) {
this.updateEvent = updateEvent;
}
#JsonView(value = AdminView.class)
public Date getDeleteEvent() {
return deleteEvent;
}
#JsonView(value = OwnerView.class)
public void setDeleteEvent(Date deleteEvent) {
this.deleteEvent = deleteEvent;
}
#JsonProperty(value = "name")
public abstract String getName();
}
Here is the account controller
#RestController
#RequestMapping("/account")
public class AccountCtrlImpl implements AccountCtrl {
#Autowired
private AccountSrv accountSrv;
public AccountSrv getAccountSrv() {
return accountSrv;
}
public void setAccountSrv(AccountSrv accountSrv) {
this.accountSrv = accountSrv;
}
#Override
#RequestMapping(value = "/get_by_id/{accountId}", method = RequestMethod.GET, headers = "Accept=application/json")
public ResponseEntity<Account> getById(#PathVariable(value = "accountId") Long accountId) {
try {
return new ResponseEntity<Account>(this.getAccountSrv().getById(accountId), HttpStatus.OK);
} catch (ServiceException e) {
return new ResponseEntity<Account>(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
#Override
#RequestMapping(value = "/get_by_mail_address/{mail_address}", method = RequestMethod.GET, headers = "Accept=application/json")
public ResponseEntity<Account> getByMailAddress(#PathVariable(value = "mail_address") String mailAddress) {
try {
return new ResponseEntity<Account>(this.getAccountSrv().getByMailAddress(mailAddress), HttpStatus.OK);
} catch (ServiceException e) {
return new ResponseEntity<Account>(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
#Override
#RequestMapping(value = "/authenticate/{mail_address}/{password}", method = RequestMethod.GET, headers = "Accept=application/json")
public ResponseEntity<Account> authenticate(#PathVariable(value = "mail_address") String mailAddress, #PathVariable(value = "password") String password) {
return new ResponseEntity<Account>(HttpStatus.NOT_IMPLEMENTED);
}
}

I really like the solution presented here to dynamically select a json view inside your controller method.
Basically, you return a MappingJacksonValue which you construct with the value you want to return. After that you call setSerializationView(viewClass) with the proper view class. In my use case, I returned a different view depending on the current user, something like this:
#RequestMapping("/foos")
public MappingJacksonValue getFoo(#AuthenticationPrincipal UserDetails userDetails ) {
MappingJacksonValue value = new MappingJacksonValue( fooService.getAll() );
if( userDetails.isAdminUser() ) {
value.setSerializationView( Views.AdminView.class );
} else {
value.setSerializationView( Views.UserView.class );
}
return value;
}
BTW: If you are using Spring Boot, you can control if properties that have no view associated are serialized or not by setting this in your application.properties:
spring.jackson.mapper.default_view_inclusion=true

I've solved my problem extending ResponseEntity like this :
public class ResponseViewEntity<T> extends ResponseEntity<ContainerViewEntity<T>> {
private Class<? extends BaseView> view;
public ResponseViewEntity(HttpStatus statusCode) {
super(statusCode);
}
public ResponseViewEntity(T body, HttpStatus statusCode) {
super(new ContainerViewEntity<T>(body, BaseView.class), statusCode);
}
public ResponseViewEntity(T body, Class<? extends BaseView> view, HttpStatus statusCode) {
super(new ContainerViewEntity<T>(body, view), statusCode);
}
}
and ContainerViewEntity encapsulate the object and the selected view
public class ContainerViewEntity<T> {
private final T object;
private final Class<? extends BaseView> view;
public ContainerViewEntity(T object, Class<? extends BaseView> view) {
this.object = object;
this.view = view;
}
public T getObject() {
return object;
}
public Class<? extends BaseView> getView() {
return view;
}
public boolean hasView() {
return this.getView() != null;
}
}
After that, we have convert only the object with the good view.
public class JsonViewMessageConverter extends MappingJackson2HttpMessageConverter {
#Override
protected void writeInternal(Object object, HttpOutputMessage outputMessage)
throws IOException, HttpMessageNotWritableException {
if (object instanceof ContainerViewEntity && ((ContainerViewEntity) object).hasView()) {
writeView((ContainerViewEntity) object, outputMessage);
} else {
super.writeInternal(object, outputMessage);
}
}
protected void writeView(ContainerViewEntity view, HttpOutputMessage outputMessage)
throws IOException, HttpMessageNotWritableException {
JsonEncoding encoding = this.getJsonEncoding(outputMessage.getHeaders().getContentType());
ObjectWriter writer = this.getWriterForView(view.getView());
JsonGenerator jsonGenerator = writer.getFactory().createGenerator(outputMessage.getBody(), encoding);
try {
writer.writeValue(jsonGenerator, view.getObject());
} catch (IOException ex) {
throw new HttpMessageNotWritableException("Could not write JSON: " + ex.getMessage(), ex);
}
}
private ObjectWriter getWriterForView(Class<?> view) {
ObjectMapper mapper = new ObjectMapper();
mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, false);
return mapper.writer().withView(view);
}
}
And to finish, I enable the converter
<mvc:annotation-driven>
<mvc:message-converters>
<bean class="wc.handler.view.JsonViewMessageConverter"/>
</mvc:message-converters>
</mvc:annotation-driven>
And that's it, I can select the View in the controller
#Override
#RequestMapping(value = "/get_by_id/{accountId}", method = RequestMethod.GET, headers = "Accept=application/json")
public ResponseViewEntity<Account> getById(#PathVariable(value = "accountId") Long accountId) throws ServiceException {
return new ResponseViewEntity<Account>(this.getAccountSrv().getById(accountId), PublicView.class, HttpStatus.OK);
}

FYI, Spring 4.1 already supported using #JsonView directly on #ResponseBody and ResponseEntity:
Jackson’s #JsonView is supported directly on #ResponseBody and ResponseEntity controller methods for serializing different amounts of detail for the same POJO (e.g. summary vs. detail page). This is also supported with View-based rendering by adding the serialization view type as a model attribute under a special key.
And in http://docs.spring.io/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-ann-jsonview you can find the much simpler solution:
#RestController
public class UserController {
#RequestMapping(value = "/user", method = RequestMethod.GET)
#JsonView(User.WithoutPasswordView.class)
public User getUser() {
return new User("eric", "7!jd#h23");
}
}
public class User {
public interface WithoutPasswordView {};
public interface WithPasswordView extends WithoutPasswordView {};
private String username;
private String password;
public User() {
}
public User(String username, String password) {
this.username = username;
this.password = password;
}
#JsonView(WithoutPasswordView.class)
public String getUsername() {
return this.username;
}
#JsonView(WithPasswordView.class)
public String getPassword() {
return this.password;
}
}

This works great :
#RequestMapping(value = "/{id}", method = RequestMethod.GET)
public void getZone(#PathVariable long id, #RequestParam(name = "tree", required = false) boolean withChildren, HttpServletResponse response) throws IOException {
LOGGER.debug("Get a specific zone with id {}", id);
Zone zone = zoneService.findById(id);
response.setContentType(MediaType.APPLICATION_JSON_VALUE);
if (withChildren) {
response.getWriter().append(mapper.writeValueAsString(zone));
} else {
response.getWriter().append(mapper.writerWithView(View.ZoneWithoutChildren.class).writeValueAsString(zone));
}
}
