2.3 application.yml

server:
  port: 80

2.4 程序入口 UsersMain80.class

package com.users;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

//启动项
@SpringBootApplication
public class UsersMain80 {
    public static void main(String[] args) {
        SpringApplication.run(UsersMain80.class,args);
    }
}

2.5 entities包和实体类

package com.users.entities;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;

@Data//getset
@AllArgsConstructor//全参构造
@NoArgsConstructor//无参构造
public class TabUsers implements Serializable {//框架要求继承的
    private String id;
    private String loginname;
    private String password;
    private String username;

}

2.6 config包和对应类

package com.users.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

@Configuration//config配置的注解
public class ApplicationContextConfig {
    //能够提供多种便捷访问远程Http服务的方法
    @Bean
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }
}

2.7 controller包和对应类

package com.users.controller;

import com.users.entities.TabUsers;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

import javax.annotation.Resource;

@RestController
@Slf4j
public class UsersController {
    public static final String URL = "http://localhost:8001";

    @Resource//依赖注入，跨域调用
    private RestTemplate rest;

    @GetMapping(value="users/tab_users_findall")//调用
    public String tab_users_findall(){
        //getForObject方法有三个参数，url、传入参数类对象、返回参数类对象
        return rest.getForObject(URL+"/tab_users_findall",String.class, TabUsers.class);//String.class仅占位，传什么参，没传所以占位
    }
}

三、运行

http://localhost/users/tab_users_findall

运行80端口需要跳转时另一个也得运行
