</generatorConfiguration>

在这里插入图片描述
测试是否搭建完成
1数据库建一个text表
在这里插入图片描述
2dao 接口

package dao;

public interface TextMapper {
    /**
     *
     * @return
     */
    String text();
}

3 service层
3.1 （TextService）

package service;

import org.springframework.stereotype.Service;


public interface TestService {
    /**
     *
     * @return
     */
    String text();
}

3.1 （TextServiceImpl）

package service;

import dao.TextMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class TextServiceImpl implements TestService{
    /**
     * @return
     */

    @Autowired
    TextMapper text;

    @Override
    public String text() {
        return text.text();
    }
}

4控制层（TextController）

package controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import service.TestService;

@Controller
public class TestController {

    @Autowired
   private TestService testService;

    @RequestMapping("/index")
    public String testPage(Model model) {
        String name = testService.text();
        System.out.println(name);
        model.addAttribute("name", name);
        return "index";
    }


}

5 views文件下新建一个（index.jsp）

<%--
  Created by IntelliJ IDEA.
  User: 小铭
  Date: 2019/12/18
  Time: 16:55
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title> </title>
  
<body>


<p>${name}</p>

</body>
</html>

6 忘了还有TextMapper.xml(放在resources的mapper下)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="dao.TextMapper">
    <select id="text" resultType="String">
        select name from text where id=1
    </select>
</mapper>
