springboot2 + mybatis-plus-generator

AutoGenerator 是 MyBatis-Plus 推出的代码生成器，可以快速生成 Entity、Mapper、Mapper XML、Service、Controller 等各个模块的代码，比 Mybatis Generator 更强大，开发效率更高。

        //代码生成器
        AutoGenerator autoGenerator = new AutoGenerator();
        //配置全局设置

        gc.setBaseColumnList(true);
        gc.setBaseResultMap(true);
        gc.setFileOverride(true);

        autoGenerator.setGlobalConfig(gc);

        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://192.168.67.132:3306/springboot-learn?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai");
        dsc.setDriverName("com.mysql.cj.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("root");

        autoGenerator.setDataSource(dsc);
        
        ```
  StrategyConfig sy = new StrategyConfig();
       sy.setInclude("user");//设置要映射的表，可以设置多张
       sy.setNaming(NamingStrategy.underline_to_camel);//从数据库表到文件的命名策略,下划线转驼峰命名
       sy.setColumnNaming(NamingStrategy.underline_to_camel);//列的命名策略
       sy.setEntityLombokModel(true);//开启lombok支持
       sy.setLogicDeleteFieldName("deleted");//设置逻辑删除字段
       sy.setVersionFieldName("version");//设置乐观锁
       sy.setRestControllerStyle(true);//开启controller的restful命名
       sy.setControllerMappingHyphenStyle(true);//开启controller中请求映射的连字符样式，如：localhost:8080/hello_id_1
       //设置自动填充
       TableFill create_time = new TableFill("create_time", FieldFill.INSERT);
       TableFill update_time = new TableFill("update_time", FieldFill.INSERT_UPDATE);
       ArrayList<TableFill> tableFills = new ArrayList<>();

    autoGenerator.execute();
