启动类

package com.keafmd;

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


@SpringBootApplication
public class App08 {

    public static void main(String[] args) {
        SpringApplication.run(App08.class, args);
    }

}

Dao层

UserDao：

package com.keafmd.dao;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;

import java.util.List;


@Repository
public class UserDao {

    @Autowired
    JdbcTemplate jdbcTemplate;

    public List userList(){
        String sql ="select * from user";
        return jdbcTemplate.queryForList(sql);

    }
}

Service层

IUserService ：

package com.keafmd.service;

import java.util.List;


public interface IUserService {

    List list();
}

UserServiceImpl：

package com.keafmd.service.impl;

import com.keafmd.dao.UserDao;
import com.keafmd.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class UserServiceImpl implements IUserService {

    @Autowired
    UserDao userDao;

    @Override
    public List list() {
        return userDao.userList();
    }
}

Controller层

UserController：

package com.keafmd.controller;

import com.keafmd.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;


@RestController
public class UserController {

    @Autowired
    IUserService userService;

    /**
     * http://127.0.0.1/userlist
     * @return
     */
    @RequestMapping("userlist")
    List UserList(){
        return userService.list();
    }
}

测试类测试

UserDaoTest：

package com.keafmd.dao;

import com.keafmd.App08;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.List;

import static org.junit.jupiter.api.Assertions.*;

@SpringBootTest(classes = App08.class)
class UserDaoTest {

    @Autowired

    @Test
    public void test(){
        List userlist = userDao.userList();
        for (Object o : userlist) {
            System.out.println(o);
        }
    }
