MyBatis-Plus 自动生成

根据表自动生成实体类，mapper，Service，ServiceImpl，Controller

1 pom.xml导入如下配置

//这个依赖我们已经导过了如果你只是导入了开启mysql-plus的依赖这个也加上
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-generator</artifactId>
    <version>3.3.1.tmp</version>
</dependency>

<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity</artifactId>
    <version>1.7</version>
</dependency>

2.我们需要在main方法下进行创建。我们创建一个Main类代码如下

package com.bdh.myatispulstest;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.GlobalConfig;
import com.baomidou.mybatisplus.generator.config.PackageConfig;
import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

public class Main {
    public static void main(String[] args) {
        //创建gennerator对象
        AutoGenerator autoGenerator = new AutoGenerator();
        //数据源
        DataSourceConfig dataSourceConfig = new DataSourceConfig();
        //是什么数据库就写对应的数据库
        dataSourceConfig.setDbType(DbType.MYSQL);
        dataSourceConfig.setUrl("jdbc:mysql://localhost:3306/news?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC");
        dataSourceConfig.setUsername("root");
        dataSourceConfig.setPassword("123456");
        dataSourceConfig.setDriverName("com.mysql.cj.jdbc.Driver");
        autoGenerator.setDataSource(dataSourceConfig);
        //全局配置
        GlobalConfig globalConfig = new GlobalConfig();
        //设置自动生成的路径
        globalConfig.setOutputDir(System.getProperty("user.dir")+"/src/main/java");
        //关闭默认打开
        globalConfig.setOpen(false);
        //作者名
        globalConfig.setAuthor("baodahai");
        autoGenerator.setGlobalConfig(globalConfig);
        //包信息
        PackageConfig packageConfig = new PackageConfig();
        //包的路径
        packageConfig.setParent("com.bdh.myatispulstest");
        //生成侧包
        packageConfig.setModuleName("generator");
        packageConfig.setController("controller");
        packageConfig.setService("service");
        packageConfig.setServiceImpl("service.impl");
        packageConfig.setMapper("mapper");
        autoGenerator.setPackageInfo(packageConfig);
        //配置策略
        StrategyConfig strategyConfig = new StrategyConfig();
        //自动添加Lombok
        strategyConfig.setEntityLombokModel(true);
        //斜杠改为驼峰命名
        strategyConfig.setNaming(NamingStrategy.underline_to_camel);
        //驼峰命名
        strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);
        autoGenerator.setStrategy(strategyConfig);

        autoGenerator.execute();
    }
}

如果我的这个你运行错误那就看其他大佬的一般这东西一大堆。如果你找到可以运行的最好把他收藏在自己的文件夹上

这个就是最简单的使用了

package com.bdh.myatispulstest.generator.controller;


import com.bdh.myatispulstest.generator.service.IUsersService;
import com.bdh.myatispulstest.generator.service.impl.UsersServiceImpl;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.stereotype.Controller;
import org.springframework.web.servlet.ModelAndView;

/**
 * <p>
 *  前端控制器
 * </p>
 *
 * @author baodahai
 * @since 2021-10-06
 */
@Controller
@RequestMapping("/generator/users")
public class UsersController {

    private IUsersService usersService;

    @PostMapping("/index")
    public ModelAndView index(){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("index");
        modelAndView.addObject("list",usersService.list());
        return modelAndView;
    }
}
