springcloud系列八整合Hystrix

feign本身是支持Hystrix的,所以不需要引入其他依赖:

我们可以看看feign这个项目的依赖,就是引入这个依赖的pom.xml

要想看这个很简单,点击那个依赖进去就可以了

点进去就可以看到

是本身就支持的,所以直接使用就可以了:

使用很简单:

在yml文件中开启:

feign:

  hystrix:

    enabled: true

看之前写的调用接口:

package com.cxy.service;

import com.cxy.dataObject.PersonDo;

import com.cxy.service.impl.PersonServiceImpl;

import org.springframework.cloud.openfeign.FeignClient;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

@FeignClient(value = "cxy-person-service",fallback=PersonServiceImpl.class)

public interface IPersonService {

    @RequestMapping("/person/{id}")

    PersonDo getPersonDoById(@PathVariable("id")Integer id);

}

那个如果服务出现问题了就进入实现类的方法中

然后填写一个实体类就可以了:

package com.cxy.service.impl;

import com.cxy.dataObject.PersonDo;

import com.cxy.service.IPersonService;

import org.springframework.stereotype.Component;

/***

 * @ClassName: PersonServiceImpl

 * @Description:

 * @Auther: 陈绪友

 * @Date: 2019/1/2821:09

 * @version : V1.0

 */

@Component

public class PersonServiceImpl implements IPersonService {

    @Override

    public PersonDo getPersonDoById(Integer id) {

        return new PersonDo(,"",,"");

    }

}

不启动person服务看结果:

是在实现类中的数据,代表生效了
