本文介绍了springcloud Feign的Hystrix支持，分享给大家，具体如下：

一、Feign client中加入Hystrix的fallback

@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); }

二、编写HystrixClientFallback类

@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;   } }

三、加入Hystrix支持
