最近又看了一下mybatis-plus，新建了一个项目试了试，表示好用，但是仅限于使用代码生成器生成各层级的代码，mp的主要使用将会在后面的项目中，先记录一下代码生成器怎么使用的。

搭建框架

新建项目编写pom，引入以下依赖

<!-- springboot依赖 -->

数据库配置文件 application.yml

代码生成器

工具类代码

public class CodeGenerator {
     /**
     * <p>
     * 读取控制台内容
     * </p>
     */
    public static String scanner(String tip) {
        Scanner scanner = new Scanner(System.in);
        StringBuilder help = new StringBuilder();
        help.append("请输入" + tip + "：");
        System.out.println(help.toString());
        if (scanner.hasNext()) {
            String ipt = scanner.next();
            if (StringUtils.isNotEmpty(ipt)) {
                return ipt;
            }
        }
        throw new MybatisPlusException("请输入正确的" + tip + "！");
    }

    public static void main(String[] args) {
        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath + "/src/main/java");
        gc.setAuthor("pengxiaofei");
        gc.setOpen(false);
//         gc.setSwagger2(true); //实体属性 Swagger2 注解
        mpg.setGlobalConfig(gc);

        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/mp?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false");
        // dsc.setSchemaName("public");
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("root");
        mpg.setDataSource(dsc);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setModuleName(scanner("模块名"));
        pc.setParent("com.mp");
        pc.setXml("mapper.xml");
        mpg.setPackageInfo(pc);

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        //是否改为驼峰规则
        strategy.setNaming(NamingStrategy.underline_to_camel);//表名
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);//字段名
        //生成的实体类继承的父类
//        strategy.setSuperEntityClass("com.mp.BaseEntity");
        //是否启用Lombok
//        strategy.setEntityLombokModel(true);
        //是否启用RestController
        strategy.setRestControllerStyle(true);
        // 公共父类
//        strategy.setSuperControllerClass("com.baomidou.ant.common.BaseController");
        // 写于父类中的公共字段
//        strategy.setSuperEntityColumns("id");
        strategy.setInclude(scanner("表名，多个英文逗号分割").split(","));
        strategy.setControllerMappingHyphenStyle(true);
        strategy.setTablePrefix(pc.getModuleName() + "_","tp_");
        mpg.setStrategy(strategy);
        mpg.execute();
    }
}
