我想到的是,如何应用国际交易日志中不同的星号(@ApplicationScoped、@SessionScoped和@RequestScoped。 我理解生命周期,但集装箱内储存在哪里? 我正在利用关于共同未来论坛的这些说明。
这些豆类如何储存在服务器上,服务器如何能知道哪些豆类属于谁。
例如,有一个星号:@SessionScoped。 存放在<代码>HTTPSession上的物体? 是否有星号(@ApplicationScoped)储存在ServletContext上的地图样本中? 如果是的话,那么安全是什么。 我猜测过这种错误,但如果有人能够告诉我什么情况,在哪里储存(范围不同),服务器如何能知道哪些人是属于谁的人,......就像还有其他什么孩子(不仅仅是 session子)一样?
我用Java EE 6所有参考资料。
例如,在幕后存放在吉大港山区喷洒物的灯塔吗? 是否有人用@ApplicationScoped储存在SerletContext的地图样本中?
对网络层面来说,情况确实如此。 如果该信标被当即时,你常常可以通过人工回收上述地图中的所有物体来发现该信。
<代码>@RequestScoped是一条特殊事项。 在网络层面,这一范围与要求归属地图相对应,但这一范围也适用于电话,例如边远会议豆,或电动信使信使处理电文。 在这种情况下,没有网上要求,因此没有请求归属地图。 可能将这些物品储存在其他地方,可能的话存放在TLS(Thread Local Deposit)中,由代理人 set开。
如果是的话,那么安全是什么。
申请和会议范围很广的豆类本身并不安全。 You必须注意校对安全,例如使用校对和安全数据结构、同步关键词,或一种固有的阅读安全(如“国家附加说明的灯塔”)。
