关于fegin 没进入 fallback 以及Hystrix Dashboard 监控界面没出图形的解决方式

Dalston.RELEASE

**版本中
使用 fegin做 服务调用，发现当 服务提供这，提供服务时候，没有进入 fallback，
需要加，**

feign:
   hystrix:
     enabled: true

调通的代码如下

controller

@RestController
@RequestMapping(value = "/sys/user")
public class UserLoginController {
    @Autowired
    private UserLoginService userLoginService;
    @Autowired
    private JwtService jwtService;


    @RequestMapping(value = "/login/{username}/{password}",method = RequestMethod.GET)
    public ReturnDTO login(@PathVariable("username") String username, @PathVariable("password") String password) {
        ReturnDTO returnDTO = new ReturnDTO();
        Map message = new HashMap();
        boolean isSuccess = userLoginService.login(username, password);

        if (isSuccess) {
            String token = jwtService.createJWT(username, 1);
            returnDTO.setCode(true);
            message.put("token", token);
            returnDTO.setMessage(message);
        } else {
            returnDTO.setCode(false);
        }
        return returnDTO;
    }

service

@FeignClient(value = "jwt-service")
public interface JwtService {

    @RequestMapping(value = "/create",method = RequestMethod.GET)
     String createJWT(@RequestParam(value = "username")String username, @RequestParam(value = "id")Integer id);

}



@FeignClient(value ="${userlogin.name}" ,fallback = UserLoginServiceHystrix.class)
public interface UserLoginService {

   @RequestMapping(value = "${userlogin.url}",method = RequestMethod.GET)
    Boolean login(@RequestParam(value = "username")  String username, @RequestParam(value = "password")  String password);
}



@Component
 class UserLoginServiceHystrix implements UserLoginService {

    @Override
    public Boolean login(@RequestParam(value = "username") String username, @RequestParam(value = "password") String password) {
        return false;
    }
}
