com.centit.framework.jdbc.dao

Class BaseDaoImpl<T extends Serializable,PK extends Serializable>

java.lang.Object

com.centit.framework.jdbc.dao.BaseDaoImpl<T,PK>

Type Parameters:

T - po类

PK - po主键类型 ; 对多个字段联合主键的可以使用Map《String, Object》类型

public abstract class BaseDaoImpl<T extends Serializable,PK extends Serializable>
extends Object

针对 EntityWithDeleteTag EntityWithVersionTag 这个jpa类只做了一个浅层实现。 如果需要循环处理引用可以调用 OrmDaoUtils.*Cascade*()相关的方法 自行实现
