public class kuang {
public static void main(String[] args){
// 需要构建一个 代码生成器 对象
AutoGenerator mpg = new AutoGenerator();
//配置策略
//1、全局配置
GlobalConfig gc = new GlobalConfig();
String projectPath=System.getProperty( "user.dir" );
gc.setOutputDir(projectPath + "/src/main/java" );
gc.setAuthor( "凯宾斯基" ); //输入作者
gc.setOpen( false ); //是否打开文件夹
gc.setFileOverride( false ); //是否覆盖
gc.setServiceName( "%Service" ); //去掉Server的I前缀
gc.setIdType(IdType.ID_WORKER); //id正常算法
gc.setDateType(DateType.ONLY_DATE); //时间格式
// gc.setSwagger2(true);//配置swagger文档
mpg.setGlobalConfig(gc);
//2、设置数据源配置
DataSourceConfig dsc= new DataSourceConfig();
dsc.setUrl( "jdbc:mysql://localhost:3306/datademo?serverTimezone=UTC" );
dsc.setDriverName( "com.mysql.cj.jdbc.Driver" );
dsc.setUsername( "root" );
dsc.setPassword( "669988" );
dsc.setDbType(DbType.MYSQL);
mpg.setDataSource(dsc);
//3、包的配置
PackageConfig pc = new PackageConfig();
pc.setParent( "com.kuang" ); //父母亲
pc.setModuleName( "bolg" ); // 模块名称
pc.setEntity( "entity" ); //实体
pc.setMapper( "mapper" ); //制图员
pc.setService( "service" ); //服务
pc.setController( "controller" ); //控制
mpg.setPackageInfo(pc);
// 策略配置
StrategyConfig strategy = new StrategyConfig();
strategy.setInclude( "user2" , "user" ); //设置要映射的表名
strategy.setNaming(NamingStrategy.underline_to_camel);
strategy.setColumnNaming(NamingStrategy.underline_to_camel);
strategy.setEntityLombokModel( true ); //自动lombok
strategy.setLogicDeleteFieldName( "deleted" );
mpg.setStrategy(strategy);
mpg.execute(); //执行
}
}
包配置生成的目录如下
可以在策略配置那里放多个表 生成对应的实体类

.pathInfo(Collections.singletonMap(OutputFile.mapperXml, "D:\\代码\\小白做毕设2022\\springboot\\src\\main\\resources\\mapper\\")); // 设置mapperXml生成路径
})
.strategyConfig(builder -> {

})
// .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板

}
自动生成 controller、entity、mapper、service、impl 层。好用
