We’ll deal with the case()and once there is any update news,we’ll let you know without any delay
我觉得选D
根据and后面这个句子的意思,如果有任何更新的消息,我们会立即告诉你们。所以我觉得应该选D比较合适。选择:promptly.
 We’ll deal with the case promptlyand once there is any update news, we’ll let you know without any delay.
因为主语用的是将来时态,promptly表示及时地。
JAVA Spring与事务, 三种时态(游离/托管/持久), 懒加载的关系
游离不用说,你自己新建对象就是游离态。
持久态,如果你的事务是放在Service层,那么在Service层及以下的方法里,从Session中获取的对象,或者save persis update等的对象就是持久态。
托管态,如果你的Service层方法返回一个PO对象,这个对象返回之后肯定是托管态。
如果你的Service层方法接受一个游离态PO对象,然后被save了,Servcie层方法返回后,这个游离态PO对象,肯定也是托管态。
懒加载异常:
如果你在Action层或者View层对托管态对象调用get方法试图获取懒加载的数据,肯定报异常。
原因是事务边界就在Service层方法处结束,Session也会在Service方法退出后关闭。
而如果使用OpenSessionInViewFilter,则Session的关闭时机会延迟到View层,其实就是JSP代码运行完毕之后才关闭。这样的话就不会报懒加载异常了。
