1、我们需要在pom.xml里添加feign依赖
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
在启动类里添加@EnableFeignClients 注解
2、编写一个feign client接口
package com.wuhongyu.eurekaclient2.feignclient;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.GetMapping;
@FeignClient(name = "client1")
@Component
public interface Client1FeignClient {
@GetMapping("/test")
String test();
}
3、controller里调用接口
@Autowired
private Client1FeignClient client1FeignClient;
@GetMapping("/feign")
public String getMsg1(){
String result = client1FeignClient.test();
log.info("result = {}",result);
return result;
}
测试结果:
