Feign Inheritance Support
Feign supports boilerplate apis via single-inheritance interfaces. This allows grouping common operations into convenient base interfaces.
UserService.java
public interface UserService {
@RequestMapping(method = RequestMethod.GET, value ="/users/{id}")
User getUser(@PathVariable("id") long id);
}UserResource.java
@RestController
public class UserResource implements UserService {
}UserClient.java
package project.user;
@FeignClient("users")
public interface UserClient extends UserService {
}| It is generally not advisable to share an interface between a server and a client. It introduces tight coupling, and also actually doesn’t work with Spring MVC in its current form (method parameter mapping is not inherited). |
