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

在

<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

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<String, Object> message = new HashMap<String, Object>();
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;
}
}
