要创建一个基于Spring Boot、Thymeleaf、MyBatis Plus和MySQL的简单表格增删改查（CRUD）项目

在这里插入图片描述

1. 创建Spring Boot项目

可以通过Spring Initializr（https://start.spring.io/ ）来创建项目，添加以下依赖：

Spring Web
Thymeleaf
MyBatis Framework
MySQL Driver
MyBatis-Plus Boot Starter

2.项目配置

2.1 依赖

yml配置

server:
  port: 8080

spring:
  datasource:
    username: root
    password: root
    url: jdbc:mysql://localhost:3306/school?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC

  thymeleaf:
    cache: false

mybatis-plus:
  mapper-locations: classpath:mapper/*Mapper.xml
  type-aliases-package: com.geekmice.sbtbal.entity

数据库表配置

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`  (

SET FOREIGN_KEY_CHECKS = 1;

3.代码实现

3.1 实体类

package com.geekmice.sbtbal.entity;

import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;

import java.io.Serializable;
import java.util.Date;

@Data
@TableName("user")
public class User implements Serializable {

    private static final long serialVersionUID=1L;
    private Long id;
    private String userName;
    private String birthday;
    private String sex;
    private String address;
    private Date insertTime;
    private Date updateTime;

}

3.2 数据访问层

package com.geekmice.sbtbal.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.geekmice.sbtbal.entity.User;
import org.springframework.stereotype.Repository;

@Repository
public interface UserMapper extends BaseMapper<User> {
}

3.3 服务层

package com.geekmice.sbtbal.service;
import com.baomidou.mybatisplus.extension.service.IService;
import com.geekmice.sbtbal.entity.User;

public interface UserService extends IService<User> {
}
package com.geekmice.sbtbal.service.impl;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.geekmice.sbtbal.entity.User;
import com.geekmice.sbtbal.mapper.UserMapper;
import com.geekmice.sbtbal.service.UserService;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService {
}

3.4 控制层

package com.geekmice.sbtbal.controller;

import com.geekmice.sbtbal.entity.User;
import com.geekmice.sbtbal.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@Controller
@RequestMapping("/users")
public class UserController {
    @Autowired
    private UserService userService;

    // 显示所有用户
    @GetMapping
    public String showAllUsers(Model model) {
        List<User> users = userService.list();
        model.addAttribute("users", users);
        return "user";
    }

    // 显示添加用户表单
    @GetMapping("/add")
    public String showAddUserForm(Model model) {
        model.addAttribute("user", new User());
        return "add-user";
    }

    // 处理添加用户请求
    @PostMapping("/addFista")
    public String addUser(@ModelAttribute User user) {
        System.out.println(user.toString());
        userService.save(user);
        return "redirect:/users";
    }

    // 显示编辑用户表单
    @GetMapping("/edit/{id}")
    public String showEditUserForm(@PathVariable Long id, Model model) {
        User user = userService.getById(id);
        model.addAttribute("user", user);
        return "edit-user";
    }

    // 处理编辑用户请求
    @PostMapping("/edit/{id}")
    public String editUser(@PathVariable Long id, @ModelAttribute User user) {
        user.setId(id);
        userService.updateById(user);
        return "redirect:/users";
    }

    // 处理删除用户请求
    @GetMapping("/delete/{id}")
    public String deleteUser(@PathVariable Long id) {
        userService.removeById(id);
        return "redirect:/users";
    }
}
