流程是consumer 项目 去调用 eureka_client项目的 getUser接口
项目是基于
【spring|spring cloud （九） 服务注册中心 项目之间通过eureka注册中心进行接口的调用】spring cloud （八） 服务注册中心 eureka 高可用集群配置搭建server端以及client端
进行开发的
首先eureka_client项目
yml配置

spring: application: name: eureka_client eureka: client: service-url: defaultZone:http://server1:8001/eureka

pojo（两个项目的都一样）

public class UserPojo {private String userName; private String userSex; private int age; public UserPojo(String userName, String userSex, int age) { this.userName=userName; this.userSex=userSex; this.age=age; }public UserPojo() { super(); }public String getUserName() { return userName; }public void setUserName(String userName) { this.userName=userName; }public String getUserSex() { return userSex; }public void setUserSex(String userSex) { this.userSex=userSex; }public int getAge() { return age; }public void setAge(int age) { this.age=age; } }

写这么一个简单的controller吧。用了Post请求方式进行测试吧 。打印一下传过来的参数userName

@RestController() public class UserController {@PostMapping("/getUser") public List getUser(@RequestParam("userName") String userName){System.out.println("---"+userName); List userPojoList = new ArrayList<>(); userPojoList.add(new UserPojo("tom","man",15)); userPojoList.add(new UserPojo("jack","man",18)); userPojoList.add(new UserPojo("ajan","wuman",17)); return userPojoList; }}

eureka_client就写这些
consumer yml配置

spring: application: name: consumer server: port: 8090 eureka: client: service-url: defaultZone:http://server1:8001/eureka

service
this.loadBalancerClient.choose("eureka_client"); 这里选择的是yml里面配置的

spring: application: name: eureka_client

这个eureka_client
这里我用的是post方式，当然，需要get方式的话就用getForEntity,还有delete、put方式，需要哪种方式，就调用哪个方法

@Service public class UserService {//ribbon负载均衡器 @Autowired private LoadBalancerClient loadBalancerClient; public List
