1.概要
这是在前面工程基础上的一个变更。
前工程:检查实验 spring cloud nacos nacos-server-2.3.0-CSDN博客
2 代码
2.1 引入依赖
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
2.2 主函数开启 openfeign
@EnableFeignClients
2.3 添加接口
package com.xjc.springcloundtest;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
@FeignClient(value = "server3")
public interface FenTest {
@RequestMapping("/fun")
String fun();
@RequestMapping("/fun/{pid}")
String fun2(@PathVariable Integer pid);
}
2.3 添加接口,并调用
package com.xjc.springcloundtest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import java.util.List;
import java.util.Random;
@RestController
public class TestController2 {
@Autowired
FenTest fenTest;
@RequestMapping("/fun2")
public String fun2(){
String ret = fenTest.fun();
return "函数2"+ret;
}
}
3 运行效果
