添加依赖

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>

1.启动类

@SpringBootApplication
@EnableDiscoveryClient
@ComponentScan("Cloud_Hystrix.*")
@EnableCircuitBreaker
public class HystrixController {
public static void main(String[] args) {
SpringApplication.run(HystrixController.class, args);
}
}

2,controller

@RestController
@RequestMapping(value="/reqmap",produces={"application/json;charaset=utf-8"},method=RequestMethod.GET)
public class HystrixReqMap {
@Autowired
HystrixService hystrixService;
@RequestMapping("")
public String reqmap(String param){
return hystrixService.reqmap(param);
}
}

3.service

@Service
public class HystrixService {
@HystrixCommand(fallbackMethod="fail")
public String reqmap(String param){
if(param.equals("aaa")){
throw new RuntimeException();
}
return param+"--hystrix";
}
public String fail(String param){
