httpmediatypenotacceptableexception spring mvc

httpmediatypenotacceptableexception spring mvc - java

I am trying to return an image as shown here https://www.baeldung.com/spring-mvc-image-media-data
All methods that are shown there are working properly, except for the last one.
#ResponseBody
#RequestMapping(value = "/image-resource", method = RequestMethod.GET)
public Resource getImageAsResource() {
return new ServletContextResource(servletContext, "/WEB-INF/images/image-example.jpg");
}
or, if we want more control over the response headers:
#RequestMapping(value = "/image-resource", method = RequestMethod.GET)
#ResponseBody
public ResponseEntity<Resource> getImageAsResource() {
HttpHeaders headers = new HttpHeaders();
Resource resource =
new ServletContextResource(servletContext, "/WEB-INF/images/image-example.jpg");
return new ResponseEntity<>(resource, headers, HttpStatus.OK);
}
When using this method, I get an error: The target resource does not have a current representation that would be acceptable to the user agent, according to the proactive negotiation header fields received in the request, and the server is unwilling to supply a default representation.
I tried many options and none of them helped. I studied these pages
HTTP Status 406 – Not Acceptable in spring MVC
"Could not find acceptable representation" using spring-boot-starter-web
Could not find acceptable representation
and many others and none of the answers on these pages helped solve the problem.
If I do:
#GetMapping(value = "/image4", produces = "image/jpeg")
then I get the error: No converter for [class org.springframework.web.context.support.ServletContextResource] with preset Content-Type 'null'
If I do:
#GetMapping(value = "/image4", consumes = "image/jpeg")
then I get the error: The origin server is refusing to service the request because the payload is in a format not supported by this method on the target resource.
This is my github project https://github.com/MyTestPerson/images
Please tell me what am I doing wrong?

You need to upgrade Spring Boot as well. You are using 2.3.0 and ApplicationContextFactory was added in 2.4, but 2.4.x is no longer supported.
You should upgrade to Spring Boot 2.5.12 or 2.6.6.

Jersey Rest Web Service with POJO Mapping remove fields with null values from JSON String [SOLVED]

I have a Jersey Rest Web Service and I would like to send json response removing all fields with null values from json response.
I'm using
#JsonInclude(JsonInclude.Include.NON_NULL)
but it doesn't work at both class and attribute level.
My resource class contain this function:
#RolesAllowed("ADMIN")
#Path("/test")
#POST
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
#ApiOperation(value = "test Create", response = TestResponse.class)
public Response Create(TestRequest request, #Context ContainerRequestContext context) {
TestResponse resp = new TestResponse();
resp.setValueA("Value A");
return Response.ok().entity(resp).build();
}
TestResponse class contain:
#ApiModel("TestResponse")
#JsonInclude(JsonInclude.Include.NON_NULL)
public class TestResponse{
#JsonProperty
private String valueA;
#JsonProperty
private String valueB;
#ApiModelProperty(value = "Value A", example = "value A")
public String getValueA(){
return valueA;
}
public SetValueA(String valueA){
this.valueA = valueA;
}
#ApiModelProperty(value = "Value B", example = "value B")
public String getValueB(){
return valueB;
}
public SetValueB(String valueB){
this.valueB = valueB;
}
}
my JSON response contain:
{"valueA":"ValueA","valueB":null}
but I would like to send back this JSON:
{"valueA":"ValueA"}
this is my application class:
#ApplicationPath("/rest")
public class App extends ResourceConfig {
public App() {
packages("it.ivan");
// Register Auth Filter here
register(AuthenticationFilter.class);
register(StartupHandler.class);
register(MultiPartFeature.class);
register(new LoggingFeature(Logger.getLogger(LoggingFeature.DEFAULT_LOGGER_NAME),
Level.INFO, LoggingFeature.Verbosity.PAYLOAD_ANY, 10000));
BeanConfig beanConfig = new BeanConfig();
beanConfig.setTitle("Ivan Rest Application");
beanConfig.setVersion("1.0.0");
beanConfig.setBasePath("/rest/");
beanConfig.setResourcePackage("it.ivan");
beanConfig.setScan(true);
register(beanConfig);
register(io.swagger.jaxrs.listing.ApiListingResource.class);
register(io.swagger.jaxrs.listing.SwaggerSerializers.class);
register(io.swagger.jaxrs.config.DefaultJaxrsConfig.class);
Swagger swagger = new Swagger();
swagger.securityDefinition("basicAuth", new BasicAuthDefinition());
new SwaggerContextService().updateSwagger(swagger);
}

Spring boot controller endpoints not enabled?

I have inherited a Spring Boot microservice which does not have a Service or API layer, it is behaving in a HATEOAS style.
This is not an optimal architecture and needs to be changed into MVC.
Currently all repository methods are accessed directly using the #RepositoryRestResource annotation.
The plan is to refactor this and add Controllers and a API layer (DTOs), however after adding a controller, swagger is not showing the Rest controllers
Also to note that when debugging the controller endpoint, it is not actually reached. It is being bypassed, which is another clue.
#CrossOrigin
#RestController
#RequestMapping("/fixing")
public class FixingController {
private final FixingRepository fixingRepository;
#Autowired
FixingController(final FixingRepository fixingRepository) {
this.fixingRepository = checkNotNull(fixingRepository, "Fixing Repository cannot be null");
}
/**
* Builds a list of Fixing strings from the database
* #return list
*/
#RequestMapping(value = "/", method = RequestMethod.GET)
public List<String> getAllFixings() {
final List<String> fixingList = new ArrayList<>();
for (Fixing fixing : fixingRepository.findAll()) {
String name = fixing.getName();
fixingList.add(name);
}
return fixingList;
}
}
This is the spring swagger config
#Configuration
public class SwaggerConfig {
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.regex("/api.*"))
.build();
}
}
The repository (note no #RepositoryRestResource annotation)
public interface FixingRepository extends JpaRepository<Fixing, Long> {
#Override
Fixing findOne(Long id);
#Override
List<Fixing> findAll();
}
When I rebuild and start the service, the controller is not shown. It only shows all the entities and their repository methods.

Any ideas what is causing this? There is nothing else I can see in the config which is preventing this from working

The issue is with your SwaggerConfig. You are only selecting a subset of your APIs (either the JPA repository sourced or your RestController sourced) via this :
.paths(PathSelectors.regex("/api.*"))
I replicated your scenario and I just commented the path selection out and I can see both type of APIs. Note that you can also use a custom predicate for selecting the paths:
#Configuration
#Import({SpringDataRestConfiguration.class})
public class SwaggerConfig {
#Autowired
#SuppressWarnings({"UnusedDeclaration"})
private ServletContext servletContext;
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.pathProvider(relativePath())
.select()
.apis(RequestHandlerSelectors.any())
// .paths(paths2())
.build();
}

Sample Rest Controller:
#CrossOrigin
#RestController
#RequestMapping("/fixing")
public class FixingController {
/**
* Builds a list of Fixing strings from the database
* #return list
*/
#RequestMapping(value = "/", method = RequestMethod.GET)
public List<String> getAllFixingsViaRestController() {
final List<String> fixingList = new ArrayList<>();
fixingList.add("foo");
fixingList.add("bar");
return fixingList;
}
}
Now my Swagger UI looks like this; you can see both the JPA Repository contributed REST APIs and the RestController contributed API (/fixing path):

HibernateValidator ignored in SpringMVC Tests

I am trying to use HibernateValidator in SpringMVC tests, but I can't get it to work.
I added it to classpath along with el and validation api deps. In WebMvcConfigurerAdapter overrided getValidator:
#Override
public Validator getValidator() {
LocalValidatorFactoryBean validatorFactoryBean = new LocalValidatorFactoryBean();
validatorFactoryBean.setProviderClass(HibernateValidator.class);
return validatorFactoryBean;
}
Binding result just doesn't have errors that should be produced by hibernate validator, and DTO has null values.
However javax validation annotations works.
What I should to do to make hibernate validator work in
spring mvc tests (with junit runner)?
UPDATE:
Here is how my test looks like:
#RunWith(SpringJUnit4ClassRunner.class)
#WebAppConfiguration
#ContextConfiguration(classes = {AppConfig.class, WebConfig.class})
public class UserControllerTest {
#Autowired
private WebApplicationContext webApplicationContext;
private MockMvc mockMvc;
#Before
public void before() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
#Test
public void RegisterUser_ValidData_UserRegistered() throws Exception {
ObjectMapper mapper = new ObjectMapper();
UserRegistrationDTO dto = new UserRegistrationDTO();
String payload = mapper.writeValueAsString(dto);
RequestBuilder request = MockMvcRequestBuilders
.post(URI.create("/users/register"))
.contentType(MediaType.APPLICATION_JSON)
.content(payload);
this.mockMvc.perform(request).andDo...
}
}

I'm getting There was an unexpected error (type=Not Found, status=404) error?

I'm getting an error There was an unexpected error (type=Not Found, status=404) error while running in mybrowser while build is successful.
Why isn't my application finding my jsp pages? What should I include in order to find those?

#/WEB-INF/pages/ in in src/java/webapp/
what i'm missing here?

You need to put the #ResponseBody on your rest methods.
This tag tells to Spring the return object is the content of the response.

As Leandro Dantas said you should add #ResponseBody on your rest methods. i.e
#RequestMapping(value="/events",
method=RequestMethod.GET
//produces=MediaType.APPLICATION_JSON_VALUE
)
#ResponseBody
public ResponseEntity<Collection<events>> getEvents(){
Collection<events> evnts = eventsservices.findAll();
return new ResponseEntity<Collection<events>>(evnts,HttpStatus.OK);
}
Annotation that indicates a method return value should be bound to the web response body link
