36.mybatis-plus代码自动生成器

很重要的功能：
参考官网：
https://baomidou.com/pages/779a6e/#快速入门
mybatis-plus自动帮你生成pojo controller .....东西

没啥废话上代码

这个依赖：
	<dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.0</version>
        </dependency>

测试类class文件用来生成

package ji;

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 Code {
    public static void main(String[] args) {
        //构建一个代码生成器对象
        AutoGenerator generator = new AutoGenerator();
        //1、全局配置
        GlobalConfig globalConfig = new GlobalConfig();
        //获取当前目录
        String path = System.getProperty("user.dir");
        //输出到哪个目录
        globalConfig.setOutputDir(path + "/src/main/java");
        globalConfig.setAuthor("高低远近");
        globalConfig.setOpen(false); //不打开文件夹
        globalConfig.setFileOverride(false); //是否覆盖
        globalConfig.setServiceName("%sService");//去Service的I前缀
//        globalConfig.setIdType(IdType.AUTO);
//        globalConfig.setDateType(DateType.ONLY_DATE);
        globalConfig.setSwagger2(true);
        generator.setGlobalConfig(globalConfig);

        //2、设置数据源
        DataSourceConfig dataSourceConfig = new DataSourceConfig();
        dataSourceConfig.setUsername("root");
        dataSourceConfig.setPassword("root");
        dataSourceConfig.setUrl("jdbc:mysql://localhost:3306/mybatis_pluss?useSSL=false&serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8");
        dataSourceConfig.setDriverName("com.mysql.cj.jdbc.Driver");
        dataSourceConfig.setDbType(DbType.MYSQL);
        generator.setDataSource(dataSourceConfig);

        //3、包的配置
        PackageConfig packageConfig = new PackageConfig();
        packageConfig.setParent("ji");
        packageConfig.setEntity("entity");
        packageConfig.setMapper("mapper");
        packageConfig.setService("service");
        packageConfig.setController("controller");
        generator.setPackageInfo(packageConfig);

        //4、策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setInclude("user");//设置要映射的表名,只需改这里即可
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        strategy.setEntityLombokModel(true);//是否使用lombok开启注解

        generator.execute();

    }
}

效果如图
