本文整理了Java中com.vaadin.ui.UI.getUIId()方法的一些代码示例，展示了UI.getUIId()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。UI.getUIId()方法的具体详情如下：
包路径：com.vaadin.ui.UI
类名称：UI
方法名：getUIId

UI.getUIId介绍

[英]Gets the id of the UI, used to identify this UI within its application when processing requests. The UI id should be present in every request to the server that originates from this UI. VaadinService#findUI(VaadinRequest) uses this id to find the route to which the request belongs.

This method is not intended to be overridden. If it is overridden, care should be taken since this method might be called in situations where UI#getCurrent() does not return this UI.
[中]获取UI的id，用于在处理请求时在其应用程序中标识此UI。UI id应该出现在从该UI发出的对服务器的每个请求中。VaadinService#findUI（VaadinRequest）使用此id查找请求所属的路由。
此方法不打算被重写。如果它被重写，则应小心，因为在UI#getCurrent（）不返回此UI的情况下可能会调用此方法。
