详解springcloud Feign的Hystrix支持

@FeignClIEnt(name="springboot-h2",fallBACk=HyStrixClIEntfallBACk.class) //在fallBACk属性中指定断路器的fallBACk 
public interface UserFeignClIEnt { 
// @GetMapPing("/user/{ID}") 
  @requestMapPing(value = "/user/{ID}",method = requestMethod.GET) 
  User findByID(@PathVariable("ID") Long ID); 
   
  @requestMapPing(value="/users",method=requestMethod.GET) 
  List<User> findAll(); 
   
  @requestMapPing(value="/post/user",method=requestMethod.POST) 
  User save(@requestbody User user); 
} 

@Component //加入spring bean中 
public class HyStrixClIEntfallBACk implements UserFeignClIEnt{ 
 
  @OverrIDe 
  public User findByID(Long ID) { 
    User u = new User(); 
    u.setname("临时名"); 
    u.setUsername("匿名"); 
    return u; 
  } 
 
  @OverrIDe 
  public List<User> findAll() { 
    return null; 
  } 
 
  @OverrIDe 
  public User save(User user) { 
    return null;
