*/
public class YefengCode {
public static void main(String[] args) {
//我们需要构建一个代码生成器对象
AutoGenerator mpg = new AutoGenerator();
//怎么样去执行，配置策略
//1、全局配置
GlobalConfig gc = new GlobalConfig();
String projectPath = System.getProperty("user.dir");//获取当前目录
gc.setOutputDir(projectPath+"/src/main/java");//输出到哪个目录
gc.setAuthor("叶枫");
gc.setOpen(false);
gc.setFileOverride(false);//是否覆盖
gc.setServiceName("%sService");//去Service的I前缀
gc.setIdType(IdType.ID_WORKER); // 设置ID自增
gc.setDateType(DateType.ONLY_DATE); // 日期格式
gc.setSwagger2(true);
mpg.setGlobalConfig(gc);
//2、设置数据源
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUsername("root");
dsc.setPassword("123456");
dsc.setUrl("jdbc:mysql://localhost:3306/mybatis_plus?useSSL=false&serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8");
dsc.setDriverName("com.mysql.cj.jdbc.Driver");
dsc.setDbType(DbType.MYSQL);
mpg.setDataSource(dsc);
//3、包的配置
PackageConfig pc = new PackageConfig();
pc.setModuleName("yefeng");
pc.setParent("com");
pc.setEntity("entity");
pc.setMapper("mapper");
pc.setService("service");
pc.setController("controller");
mpg.setPackageInfo(pc);
//4、策略配置
StrategyConfig strategy = new StrategyConfig();
strategy.setInclude("user");//设置要映射的表名,只需改这里即可
strategy.setNaming(NamingStrategy.underline_to_camel);
strategy.setColumnNaming(NamingStrategy.underline_to_camel);
strategy.setEntityLombokModel(true);//是否使用lombok开启注解
strategy.setLogicDeleteFieldName("deleted");
//自动填充配置
TableFill gmtCreate = new TableFill("gmt_create", FieldFill.INSERT);
TableFill gmtUpdate = new TableFill("gmt_update", FieldFill.INSERT_UPDATE);
ArrayList<TableFill> tableFills = new ArrayList<>();
tableFills.add(gmtCreate);
tableFills.add(gmtUpdate);
strategy.setTableFillList(tableFills);
//乐观锁配置
strategy.setVersionFieldName("version");
strategy.setRestControllerStyle(true);//开启驼峰命名
strategy.setControllerMappingHyphenStyle(true); //localhost:8080/hello_id_2
mpg.setStrategy(strategy);
mpg.execute();//执行
}
}
