Spring cloud openfeign status 404 - spring

Question

I'am working on a miscroservices example, i've got 4 micro-service:
- eureka-server (discovery)
- gateway-service(zuul proxy)
- resource-service (feign client)
- user-service (user crud example)
Everything works fine; even when i call user-service api's through proxy it works perfectly;
But my goal here is to call user-service api's using feign client, and at this point i get the error
feign.FeignException$NotFound: status 404 reading UserDetailsServiceFeign#getUserById(Long)

This is my main class:
#EnableFeignClients
#EnableEurekaClient
#SpringBootApplication
public class ResourceServiceApplication {
public static void main(String[] args) {
SpringApplication.run(ResourceServiceApplication.class, args);
}
}
This is my FeignClient interface:
#FeignClient(name = "user-service")
public interface UserDetailsServiceFeign {
#PostMapping(value = "/saveUpdate")
UserDetailsDTO saveUpdate(#RequestBody UserDetailsDTO inputUser);
#GetMapping(value = "/getById/{id}")
UserDetailsDTO getUserById(#PathVariable(name = "id") Long id);
#GetMapping(value = "/getByName/{name}")
List<UserDetailsDTO> getUserByName(#PathVariable(name = "name") String name);
}
This is my controller api class
#RestController
#RequestMapping("/api")
public class UserDetailsResourceController {
#Autowired
private UserDetailsServiceFeign userDetailsServiceFeign;
#PostMapping(value = "/saveUpdate")
public UserDetailsDTO saveUpdate(#RequestBody UserDetailsDTO inputUser) {
return userDetailsServiceFeign.saveUpdate(inputUser);
}
#GetMapping(value = "/getById/{id}")
public UserDetailsDTO getUserById(#PathVariable(name = "id") Long id) {
return userDetailsServiceFeign.getUserById(id);
}
#GetMapping(value = "/getByName/{name}")
public List<UserDetailsDTO> getUserByName(#PathVariable(name = "name") String name) {
return userDetailsServiceFeign.getUserByName(name);
}
}
this is my conf properties:
spring:
application:
name: resource-service
eureka:
client:
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://localhost:8661/eureka
instance:
hostname: localhost
server:
port: 8182

Answer 1

Sadly, i forgot to mention the mapping prefix in Feign interface; which results in path misleading.
