1.2 记忆要点
1.2.1 引入对象
Autowired
DiscoveryClient discoveryClient;
1.2.2 获取服务实例
ListServiceInstance serviceInstances discoveryClient.getInstances(server3);
int index new Random().nextInt(serviceInstances.size());
ServiceInstance serviceInstance serviceInstances.get(index);
1.2.3 利用服务实例调用函数
String url http://serviceInstance.getHost():serviceInstance.getPort()/fun; 2.代码变更
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 {AutowiredDiscoveryClient discoveryClient;//Autowired//FenTest fenTest;AutowiredRestTemplate restTemplate;RequestMapping(/fun2)public String fun2(){ListServiceInstance serviceInstances discoveryClient.getInstances(server3);int index new Random().nextInt(serviceInstances.size());ServiceInstance serviceInstance serviceInstances.get(index);//String url http://localhost:8080/fun;//String url http://server3/fun;String url http://serviceInstance.getHost():serviceInstance.getPort()/fun;//String ret fenTest.fun();String ret restTemplate.getForObject(url,String.class);return 函数2ret;}
}3 运行结果
