    package com.xxxx.seckill;

代码如下：

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.annotation.IdType;
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.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import org.junit.jupiter.api.Test;

public class CodeGenerator {
@Test
public void run() {

    // 1、创建代码生成器
    AutoGenerator mpg = new AutoGenerator();
    ///Users/pengqiulei/Downloads/IDEA项目聚集地/generator
    // 2、全局配置
    GlobalConfig gc = new GlobalConfig();
    gc.setOutputDir("/Users/pengqiulei/Downloads/IDEA项目聚集地/project" + "/src/main/java");
    gc.setAuthor("pengqiulei");
    gc.setOpen(false); //生成后是否打开资源管理器
    gc.setFileOverride(false); //重新生成时文件是否覆盖
    gc.setServiceName("%sService");    //去掉Service接口的首字母I
    gc.setIdType(IdType.ID_WORKER_STR); //主键策略
    gc.setDateType(DateType.ONLY_DATE);//定义生成的实体类中日期类型
    gc.setSwagger2(true);//开启Swagger2模式

    mpg.setGlobalConfig(gc);

    // 3、数据源配置
    DataSourceConfig dsc = new DataSourceConfig();
    dsc.setUrl("jdbc:mysql://localhost:3306/seckill?serverTimezone=Asia/Shanghai");
    dsc.setDriverName("com.mysql.cj.jdbc.Driver");
    dsc.setUsername("root");
    dsc.setPassword("xxxxxxx");
    dsc.setDbType(DbType.MYSQL);
    mpg.setDataSource(dsc);

    // 4、包配置
    PackageConfig pc = new PackageConfig();
    pc.setModuleName("seckill"); //生成代码在哪里的模块名  com.example.generator下生成代码
    pc.setParent("com.xxxx");
    pc.setController("controller");
    pc.setEntity("entity");
    pc.setService("service");
    pc.setMapper("mapper");
    mpg.setPackageInfo(pc);

    // 5、策略配置
    StrategyConfig strategy = new StrategyConfig();
    strategy.setInclude("t_user");//生成的表多表用,分隔
    strategy.setNaming(NamingStrategy.underline_to_camel);//数据库表映射到实体的命名策略
    strategy.setTablePrefix("t_"); //生成实体时去掉表前缀

    strategy.setColumnNaming(NamingStrategy.underline_to_camel);//数据库表字段映射到实体的命名策略
    strategy.setEntityLombokModel(true); // lombok 模型 @Accessors(chain = true) setter链式操作

    strategy.setRestControllerStyle(true); //restful api风格控制器
    strategy.setControllerMappingHyphenStyle(true); //url中驼峰转连字符

    mpg.setStrategy(strategy);

    // 6、执行
    mpg.execute();}}
