aj在持久化方面的使用

利用aj实现aop.

public aspect DomainObjectLifecycle extends DomainObjectSensitive
{
    after() returning(IDomainObject domainObject): create()
    {
        UnitOfWork.getCurrent().registerCreated(domainObject);
    }

    after(IDomainObject domainObject): modify(domainObject)
    {
        UnitOfWork.getCurrent().registerDirty(domainObject);
    }
   
    after(IDomainObject domainObject): destroy(domainObject)
    {
        UnitOfWork.getCurrent().registerDestroyed(domainObject);     
    }
}

 

public abstract aspect DomainObjectSensitive {
protected pointcut create():
!within(com.sysway..data..*)&&
(call(IDomainObject+.new(..))||
call(IDomainObject+ *.reflectCreate(..)))&&
!call(DummyDomainObject+.new());

 

protected pointcut modify(IDomainObject domainObject):
        target(domainObject+) &&
        (call(void IDomainObject+.set*(..)) ||
        call(void IDomainObject+.add*(..)) ||
        call(void IDomainObject+.remove*(..))) &&
        !call(static void IDomainObject+.set*Finder(..)) &&
!cflow(create()) &&
    !within(com.sysway..data..*);

 

protected pointcut destroy(IDomainObject domainObject):
        target(domainObject+)&&
        call(void IDomainObject.destroy());

 

protected pointcut saving():execution(public void UnitOfWork.saving());

}
