导入依赖

<!--mp-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.0.5</version>
        </dependency>
<!--mp auto code-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.4.1</version>
        </dependency>
        <dependency>

        </dependency>

编写自动生成器,然后运行

public class AutoCode {
    public static void main(String[] args) {
        //构建生成器对象
        AutoGenerator mpg = new AutoGenerator();

        //配置策略
        //1.全局配置
        //2.将全局配置给生成器
        GlobalConfig gc = new GlobalConfig();
        //获得当前目录
        String projectPath = System.getProperty("user.dir");
        //将代码生成到当前路径下的src/main/java下
        gc.setOutputDir(projectPath+"/src/main/java");
        gc.setAuthor("Strike");//设置代码作者
        gc.setOpen(false);//设置是否打开文件夹
        gc.setFileOverride(false);//设置是否生成后文件覆盖
        gc.setServiceName("^%sService");//去掉service的i前缀
        gc.setIdType(IdType.ID_WORKER);
        gc.setDateType(DateType.ONLY_DATE);//设置日期类型
        gc.setSwagger2(true);//设置开启Swagger
        mpg.setGlobalConfig(gc);

        //3.设置数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/vueblog?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC");
        dsc.setDriverName("com.mysql.cj.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("123456");
        dsc.setDbType(DbType.MYSQL);
        mpg.setDataSource(dsc);

        //4.包的配置(各个包的包名位置)
        PackageConfig pc = new PackageConfig();
        pc.setModuleName("blog");
        pc.setParent("com.strike");
        pc.setEntity("entity");
        pc.setMapper("mapper");
        pc.setService("service");
//        pc.setController("controller");
        mpg.setPackageInfo(pc);

        //5.策略配置
        StrategyConfig strategyConfig = new StrategyConfig();
        strategyConfig.setInclude("m_blog");//设置要映射的表名
        strategyConfig.setNaming(NamingStrategy.underline_to_camel);
        strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);
        strategyConfig.setEntityLombokModel(true);

//        strategyConfig.setLogicDeleteFieldName("xxx");//逻辑删除的字段
//        TableFill gmtCreate = new TableFill("gmt_create", FieldFill.INSERT);//自动填充
//        TableFill gmtModified = new TableFill("gmt_modified", FieldFill.INSERT);
//        ArrayList<TableFill> tableFills = new ArrayList<>();
//        tableFills.add(gmtCreate);
//        tableFills.add(gmtModified);


        strategyConfig.setRestControllerStyle(true);
        strategyConfig.setControllerMappingHyphenStyle(true);
        mpg.setStrategy(strategyConfig);

        //执行
        mpg.execute();
    }
}
