SpringBoot2.0整合SpringCloud Finchley @hystrixcommand注解找不到解决方案

SpringBoot2.0整合SpringCloud Finchley @hystrixcommand注解找不到解决方案

hystrix参数使用方法

通过注解@HystrixCommand的commandProperties去配置，

如下就是hystrix命令超时时间命令执行超时时间，为1000ms和执行是不启用超时

@RestController

public class MovieController {

@Autowired

private RestTemplate restTemplate;

@GetMapping("/movie/{id}")

@HystrixCommand(commandProperties = {

@HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "1000"),

@HystrixProperty(name = "execution.timeout.enabled", value = "false")},fallbackMethod = "findByIdFallback")

public User findById(@PathVariable Long id) {

return this.restTemplate.getForObject("http://microservice-provider-user/simple/" + id, User.class);

}

/**

* fallback方法

* @param id

* @return

*/

public User findByIdFallback(Long id) {

User user = new User();

user.setId(5L);

return user;

}

}

问题描述：

笔者在使用Spring Boot 2.0整合Spring Cloud Finchley.RC2版本时，使用断路器 Hystrix时候发现@hystrixcommand注解找不到，由于SJcvwsqLpring Boot 2.0刚出没多久，所以这块资料网上很少，查阅资料说是新版本中不包含此注解了，需要重新引入。
