  • 使用Feign作为客户端调用工具

    • service接口 

    • package zkrun.top.service;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestMapping;

@FeignClient("msc-provider")    //@FeignClient("服务名")
@Component
public interface Hystrix_FeignService {


    @RequestMapping(value = "/info/get")
    public String request();

}

    • controller 

      package zkrun.top.controller;


import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import zkrun.top.service.Hystrix_FeignService;

@RestController
public class Hystrix_FeignController {

    @Autowired
    Hystrix_FeignService hystrix_feignService;

    @RequestMapping(value = "/feign/info/get",method = RequestMethod.GET)
    @HystrixCommand(fallbackMethod = "hystrix_fallback")
    public String request()
    {
       return this.hystrix_feignService.request();
    }

    public String hystrix_fallback()
    {
        return "当前服务故障，服务熔断已启动！";

    }

}

    • 主类（注解有点多） 

    • package zkrun.top;


import org.springframework.boot.SpringApplication;
