我目前正在开发一个大约 10 页和中等复杂性的 Web 应用程序。前几天我们开始了性能测试，在日志中可以注意到以下异常：

我一直在阅读论坛，其中大多数会提到以下属性，这些属性控制存储在一个特定会话中的最大视图数：

com.sun.faces.numberOfViewsInSession com.sun.faces.numberOfLogicalViews

在尝试设置默认值以外的值之前，我想先看看我们在会话中有多少视图。我正在看类似的东西：

用户：x，视图：y，逻辑视图：z。

请问有谁知道我怎样才能得到这种数据？

PS 该应用程序在 WASCE 环境中运行并使用 myfaces-1.2.6。

com.sun.faces.* 是 Mojarra 而不是 MyFaces。您应该改用org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION。
