com.google.api.gax.rpc.UnknownException in Springboot app deployed on Azure app service

I have a springboot application deployed on Azure app service. I am trying to get response from detectIntent method of dialogflow. I am getting the
com.google.api.gax.rpc.UnknownException: io.grpc.StatusRuntimeException: UNKNOWN: Channel Pipeline: [WriteBufferingAndExceptionHandler#0, DefaultChannelPipeline$TailContext#0] exception.
The app is deployed as war file on the azure app service. Locally it works fine (IDE) also the war file runs successfully in tomcat server.
protected DetectIntentResponse getActionFromNLPV2(String userQuery, String sessionId){
log.info("Start of getActionFromNLPV2");
DetectIntentResponse response =null;
try {
try ( SessionsClient sessionsClient = SessionsClient.create(sessionsSettings)) {
log.info("Start of getActionFromNLPV2");
SessionName session = SessionName.of(projectId, sessionId);
log.info("SessionName " + session);
Builder textInput = TextInput.newBuilder().setText(userQuery).setLanguageCode("en");
QueryInput queryInput = QueryInput.newBuilder().setText(textInput).build();
response = sessionsClient.detectIntent(session, queryInput);
if (response!=null) {
return response;
} else {
return null;
}
}
} catch (Exception e) {
log.error("Exception from getting action data from NLP" + e);
return null;
}

thymeleaf different behavior (via database and resttemplate)

everybody.
I have two application.
The first one is a CRUD spring boot JPA web mvc application.
it works fine with these code. (via repositories database)
#RequestMapping(value = { "/newUser" }, method = RequestMethod.GET)
public String newUser(ModelMap model) {
User user = new User();
List<UserProfile> roles = userProfileRepository.findAll();
model.addAttribute("user", user);
model.addAttribute("allRoles", roles);
return "registration";
}
#RequestMapping(value = { "/newUser" }, method = RequestMethod.POST)
public String saveUser(#Valid User user, BindingResult result,
ModelMap model) {
if (result.hasErrors()) {
List<UserProfile> roles = userProfileRepository.findAll();
model.addAttribute("allRoles", roles);
model.addAttribute("user", user);
return "registration";
}
userRepository.save(user);
return "registrationsuccess";
}
and a part of registration.html is
<select class="form-control input-sm" id="userProfiles" name="userProfiles" multiple="multiple" th:required="true">
<option th:each="role : ${allRoles}"
th:value="${{role}}"
th:text="${role.type}"
th:selected="${role.id == 1}"
>Role
</option>
</select>
the code above works fine.
The second application is a resttemplate based spring boot
#RequestMapping(value = { "/newUser" }, method = RequestMethod.GET)
public String newUser(ModelMap model) {
User user = new User();
RestTemplate restTemplate = new RestTemplate();
List<UserProfile> userProfiles = Arrays.asList(restTemplate.getForObject("http://localhost:8080/api/roles", UserProfile[].class));
ArrayList<UserProfile> roles = new ArrayList<>(userProfiles);
model.addAttribute("user", user);
model.addAttribute("allRoles", roles);
return "registration";
}
#RequestMapping(value = { "/newUser" }, method = RequestMethod.POST)
public String saveUser(#Valid User user, BindingResult result,
ModelMap model) {
if (result.hasErrors()) {
RestTemplate restTemplate = new RestTemplate();
List<UserProfile> userProfiles = Arrays.asList(restTemplate.getForObject("http://localhost:8080/api/roles", UserProfile[].class));
ArrayList<UserProfile> roles = new ArrayList<>(userProfiles);
model.addAttribute("allRoles", roles);
model.addAttribute("user", user);
return "registration";
}
RestTemplate restTemplate = new RestTemplate();
restTemplate.postForObject("http://localhost:8080/api/users", user, User.class);
return "registrationsuccess";
}
multiple select form is the same like first app has (identical)
But the second app throws exceptions when registration.html is called
There was an unexpected error (type=Internal Server Error, status=500).

PS. I've tested all the methods (PUT, GET, DELETE and POST) via PostMan. And it works fine.
I don't understand the different behavior of thymeleaf..

Remove the double-bracket syntax from th:value="${{role}}" as described in the stacktrace.
The double brackets apply a conversion service, typically used for things like dates. This in the Data Conversion section of the docs.

I've just implemented org.springframework.core.convert.converter.Converter;
#Component
public class RoleToUserProfileConverter implements Converter<Object, UserProfile>{
#Autowired
UserProfileService userProfileService;
public UserProfile convert(Object element) {
Integer id = Integer.parseInt((String)element);
return userProfileService.findById(id);
}
}
and modified a little bit this form
<select class="form-control input-sm" id="userProfiles" name="userProfiles" multiple="multiple" th:required="true">
<option th:each="role : ${allRoles}"
th:value="${role.id}"
th:text="${role.type}"
th:selected="${role.id == 1}"
>Role
</option>
</select>
So now, thymeleaf transform value to object.
Thanks everybody!

How to serialize a java.security.Principal?

I have written this code:
#RestController
public class UserController {
private final static Logger LOGGER = LoggerFactory.getLogger(UserController.class);
#RequestMapping(path = "/", produces = "application/json")
public #ResponseBody Principal getUser(HttpServletRequest request) throws Exception {
try {
Principal principal = request.getUserPrincipal();
LOGGER.debug("User found" + principal.toString());
return principal;
}
catch (Exception e) {
LOGGER.debug("User not found : " + e.getMessage());
throw e;
}
}
}
But it throws:
java.lang.IllegalStateException: getOutputStream() has already been
called for this response
How do I serialize that object? What makes an object serializable for Spring Boot? During the execution, the actual object type is the org.apache.catalina.realm.GenericPrincipal implementation of Principal

By exposing a Principal instance (such as an instance of GenericPrincipal from Apache Tomcat) in your web API, you may ended up leaking some sensitive details you don't intent to.
A better approach would be creating a DTO and then mapping only the principal details you want to expose to this DTO.
Despite the security breaches, let me just clarify what may be wrong with the serialization itself.
If you create an instance of GenericPrincipal and then attempt to serialize it to JSON using ObjectMapper directly, you'll see it won't succeed:
ObjectMapper mapper = new ObjectMapper();
Principal principal = new GenericPrincipal("john.doe", "secret", Arrays.asList("admin"));
String json = mapper.writeValueAsString(principal);
The exception is:
Exception in thread "main" com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Direct self-reference leading to cycle (through reference chain: org.apache.catalina.realm.GenericPrincipal["userPrincipal"])
If you check the GenericPrincipal source code, you'll see a userPrincipal field:
protected final Principal userPrincipal;
Well, you could attempt to use mix-in annotations, but it's probably not worth it. Just create a DTO and expose only what you need.

}
apiMessasge.setCode(-1);
}
}
return apiMessasge;
}
}
This is in Android
Uri resultUri = result.getUri();
File file = new File(resultUri.getPath());
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
MultipartBody.Part body = MultipartBody.Part.createFormData("file", file.getName(), requestFile);
And this is in APiService.class
#Multipart
#Headers("Content-Type:application/json")
#POST("/beongae/api/{version}/profile/upload/{name}")
Call<ApiMessasge> upload(#Path("version") int version, #Path("name") String fileName
, #Part MultipartBody.Part file);
And This is the error message in Spring Boot

But, It's done well when I use Postman.
Please tell me what is the problem and how to solve

Try to modify your service a little bit and try
#Part("file\"; filename=\"filename.png\" ")

camel stream closed error in rest service csv reader

I have to read a csv file, when i invoke a camel rest service url (with SpringBoot):
http://localhost:8080/camel/csv
This is the route builder:
#Component
public class CamelContextConf extends RouteBuilder{
static final Logger logger = Logger.getLogger(CamelContextConf.class);
#Override
/**
* http://localhost:8080/camel/csv
*/
public void configure() throws Exception {
restConfiguration().component("servlet");
rest("/csv").get().to("direct:csvprocessor");
CsvDataFormat csv = new CsvDataFormat();
csv.setDelimiter(";");
csv.setSkipHeaderRecord(true);
from("direct:csvprocessor")
.to("file:src/main/resources/?fileName=sample-data.csv&noop=true")
//.split(body().tokenize("\\n"))
.unmarshal(csv)
.to("bean:myCsvHandler?method=doHandleCsvData").endRest();
logger.info("** Route config ok");
}
}
This is the handler:
#Component
public class MyCsvHandler {
public void doHandleCsvData(List<List<String>> csvData)
{
int i = 1;
for (List<String> rows : csvData){
System.out.println("Riga: " + (i++));
for (String column : rows){
System.out.print(column + " ; ");
}
}
}
}
I have to set the camel servlet endpoint in this class
#Configuration
#SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class,
DataSourceTransactionManagerAutoConfiguration.class })
#ComponentScan(basePackages={"... list of"})
#EnableTransactionManagement
#EnableAutoConfiguration
public class WebApplicationAware extends SpringBootServletInitializer {
private static Class<WebApplicationAware> applicationClass = WebApplicationAware.class;
static final Logger logger = Logger.getLogger(WebApplicationAware.class);
public static void main(String[] args) {
SpringApplication.run(applicationClass, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
#Bean
public ServletRegistrationBean camelServletRegistrationBean() {
ServletRegistrationBean registration = new ServletRegistrationBean(new CamelHttpTransportServlet(), "/camel/*");
registration.setName("CamelServlet");
logger.info("** CamelServlet initialized..");
return registration;
}
}
but it give me this error when i invoke the rest route by browser:

why ? Whats the problem?
Thanks in advice

If you would like to enrich the message you can use the .pollEnrich() from the Java DSL like this:
from("direct:csvprocessor")
.pollEnrich("file:src/main/resources/?fileName=sample-data.csv&noop=true&idempotent=false")
...
UPDATE
If you would like to read the same file again and again then you could use
.pollEnrich("file://mydir?fileName=test.csv&noop=true&idempotent=false") and in this sample (it's based on your first post) the route sends back HTTP 200 OK with the string "ok" if there wasn't any exception during the processing.
from("direct:csvprocessor")
.pollEnrich("file:src/main/resources/?fileName=sample-data.csv&noop=true&idempotent=false")
.unmarshal(csv)
.to("bean:myCsvHandler?method=doHandleCsvData")
.setBody(constant("ok"))
.setHeader(Exchange.HTTP_RESPONSE_CODE, constant(200));
