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; } }

配置文件

server: port: 9002 eureka: client: service-url: defaultZone: http://10.10.8.101:9000/eureka/ spring: application: name: sys-user-consumer messages: fallback-to-system-locale: true management: security: enabled: false userlogin: name: sys-user-service url: /sys/user/login feign: hystrix: enabled: true
