执行命令、生成sys_user表对应PO、mapper、mapper.xml

mvn mybatis-generator:generate

集成SpringMVC、thymeleaf

添加依赖

application.yml配置

server:
  port: 8080

spring:
  datasource:
    druid:
      url: jdbc:mysql://127.0.0.1:3306/mybatis-generator?useUnicode=true&characterEncoding=utf-8&useSSL=false

  thymeleaf:
    cache: false
    mode: LEGACYHTML5
    encoding: UTF-8
    servlet:
      content-type: text/html

入口类增加注解

package com.zhun;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import tk.mybatis.spring.annotation.MapperScan;

@MapperScan(basePackages = {"com.zhun.**.mapper"})
@SpringBootApplication
public class MybatisGeneratorDemoApplication {

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

增加服务接口

package com.zhun.system.service;

import com.github.pagehelper.PageInfo;
import com.zhun.system.po.UserPO;

import java.util.List;

public interface UserService {
    UserPO get(Long id);

    int insert(UserPO userPO);

    int update(UserPO userPO);

    int delete(Long id);

    List<UserPO> list(UserPO userPO);

    PageInfo<UserPO> page(int pageNum, int pageSize, UserPO userPO);
}

创建服务层实现

package com.zhun.system.service.impl;

import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.zhun.system.mapper.UserMapper;
import com.zhun.system.po.UserPO;
import com.zhun.system.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public UserPO get(Long id) {
        return userMapper.selectByPrimaryKey(id);
    }

    @Override
    public int insert(UserPO userPO) {
        return userMapper.insert(userPO);
    }

    @Override
    public int update(UserPO userPO) {
        return userMapper.updateByPrimaryKey(userPO);
    }

    @Override
    public int delete(Long id) {
        return userMapper.deleteByPrimaryKey(id);
    }

    @Override
    public List<UserPO> list(UserPO userPO) {
        return userMapper.select(userPO);
    }

    @Override
    public PageInfo<UserPO> page(int pageNum, int pageSize, UserPO userPO) {
        PageHelper pageHelper = new PageHelper();
        pageHelper.startPage(pageNum, pageSize);
        PageInfo<UserPO> pageInfo = new PageInfo<>(userMapper.select(userPO));
        return pageInfo;
    }
}

创建控制器

package com.zhun.system.controller;

import com.github.pagehelper.PageInfo;
import com.zhun.system.po.UserPO;
import com.zhun.system.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @ResponseBody
    @GetMapping("list")
    public PageInfo list(@RequestParam(required = false, defaultValue = "1") Integer pageNumber,
                   @RequestParam(required = false, defaultValue = "5")  Integer pageSize,
                   @RequestParam(required = false) UserPO userPO) {
        return userService.page(pageNumber, pageSize, userPO);
    }

    @GetMapping
    public String index(ModelMap modelMap) {
        modelMap.put("page", userService.page(1, 5, new UserPO()));
        return "index";
    }
}

创建index.html

• 目录 ${basedir}/src/main/resources/templates/index.html

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>

<table>
    <thead>
    <th>
        <td>序号</td>
        <td>昵称</td>
        <td>账号</td>
        <td>邮箱</td>
    </th>
    </thead>
    <tbody>
    <tr th:each="data,state: ${page.list}">
        <td th:text="${state.index+1}"></td>
        <td th:text="${data.name}"></td>
        <td th:text="${data.account}"></td>
        <td th:text="${data.email}"></td>
    </tr>
    </tbody>
</table>
</body>
</html>
