When I call another Service (User-service) from one service (API-gateway) Using Feign Client, I'm getting an Error
There are two services
In my API-gateway
FeignClient
@FeignClient(contextId = "user-by-email",name = "user-service")
@Service
public interface UserByEmail {
@RequestMapping(value = "/email/{email}", consumes= MediaType.APPLICATION_JSON_VALUE)
User findByEmail(@PathVariable("email") String email);
}
Controller
@RequestMapping("/test")
public class TestController {
@Autowired
private UserByEmail userByEmail;
@GetMapping(value = "/{email:.+}")
public ResponseEntity testUser(@PathVariable("email") String username) {
return ResponseEntity.ok(userByEmail.findByEmail(username));
}
}
I need to call the following (User-service)
Controller
@EnableFeignClients
@RestController
public class UserController extends BaseController<User> {
@Autowired
private UserService userService;
@PostConstruct
public void binder() {
init(this.userService);
}
@GetMapping(value = "/email/{email}")
public ResponseEntity findByEmail(@PathVariable("email") String email) {
return ResponseEntity.ok(userService.findByEmail(email));
}
}
Repository
@Override
public User findByEmail(String email) {
Query query = new Query(Criteria.where("email").is(email).and("status").is(1));
return mongoOperations.findOne(query, User.class);
}
Service
@Override
public User findByEmail(String email) {
return userDao.findByEmail(email);
}
The Error I'm getting is ..
<Map>
<timestamp>1583924335777</timestamp>
<status>406</status>
<error>Not Acceptable</error>
<message>Could not find acceptable representation</message>
<trace>org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation
at org.springframework.web.servlet.mvc.method.annotation.AbstractMessageConverterMethodProcessor.writeWithMessageConverters(AbstractMessageConverterMethodProcessor.java:246)
Can anyone please explain What is wrong with my code, And give your valuable solutions
(Basically I need to create Security in API-gateway, in order to control the access of other services)
Try Implementing Feign client as below:
@FeignClient(name = "user-service")
public interface UserByEmail {
@RequestMapping(method = RequestMethod.GET, value = "/email/{email}", consumes = "application/json")
User findByEmail(@PathVariable("email") String email);
}
also make sure the Fields passed over JSON matchers User
POJO.
I've got the solution to my Question
FeignClient
@FeignClient(contextId = "user-by-email",name = "user-service")
@Service
public interface UserByEmail {
@RequestMapping(value = "/email/{email}", consumes= MediaType.APPLICATION_JSON_VALUE)
User findByEmail(@RequestParam("email") String email);
}
Controller
@RequestMapping("/test")
public class TestController {
@Autowired
private UserByEmail userByEmail;
@GetMapping(value = "/{email}")
public ResponseEntity testUser(@RequestParam("email") String username) {
return ResponseEntity.ok(userByEmail.findByEmail(username));
}
}
In User-service
Controller
@EnableFeignClients
@RestController
public class UserController extends BaseController<User> {
@Autowired
private UserService userService;
@PostConstruct
public void binder() {
init(this.userService);
}
@GetMapping(value = "/email/{email}")
public ResponseEntity findByEmail(@RequestParam("email") String email) {
return ResponseEntity.ok(userService.findByEmail(email));
}
}
