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;    }}
