UI.close介绍

[英]Marks this UI to be #detach() from the session at the end of the current request, or the next request if there is no current request (if called from a background thread, for instance.)

The UI is detached after the response is sent, so in the current request it can still update the client side normally. However, after the response any new requests from the client side to this UI will cause an error, so usually the client should be asked, for instance, to reload the page (serving a fresh UI instance), to close the page, or to navigate somewhere else.

Note that this method is strictly for users to explicitly signal the framework that the UI should be detached. Overriding it is not a reliable way to catch UIs that are to be detached. Instead, UI.detach()should be overridden or a DetachListener used.
[中]在当前请求结束时将此UI标记为#detach（），如果没有当前请求，则将其标记为下一个请求（例如，如果从后台线程调用）
响应发送后，UI被分离，因此在当前请求中，它仍然可以正常更新客户端。但是，在响应之后，客户端对该UI的任何新请求都会导致错误，因此通常应该要求客户端重新加载页面（为新的UI实例提供服务）、关闭页面或导航到其他地方。
请注意，这种方法严格来说是为了让用户明确地向框架发出应该分离UI的信号。重写它并不是捕获要分离的UI的可靠方法。而是UI。应该重写detach（）或使用DetachListener。
