springcloud集成feign

基於上篇文章給出feign實例代碼

package com.example.feign;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.openfeign.EnableFeignClients;

/**
 * 開啓springcloud feign 功能
 */
@EnableFeignClients
@SpringBootApplication
public class FeignApplication {

    public static void main(String[] args) {
        SpringApplication.run(FeignApplication.class, args);
    }
}

service

package com.example.feign;


import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

@FeignClient(value = "producer")
public interface FeignService {
    /**
     * 綁定服務
     * @param name
     * @return
     */
    @RequestMapping(value = "/get",method = RequestMethod.GET)
    String hello(@RequestParam(value = "name") String name);
}

controller

package com.example.feign;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestFeignController {
    @Autowired
    FeignService feignService;

    @GetMapping(value = "/hello")
    public String hello(@RequestParam String name) {
        return feignService.hello(name);
    }
}
