Question

我目前正在开发一个大约10页且中等复杂度的Web应用程序。我们前几天开始进行性能测试，并在日志中注意到以下异常：

我一直在阅读论坛，他们中的大多数都会提到控制一个特定会话中存储的最大观看次数的以下属性：

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

在尝试设置默认值以外的值之前，我希望首先看到会话中有多少视图。我正在寻找类似的东西：

用户：x，views：y，logicalViews：z。

有谁知道我怎样才能获得这类数据？

P.S。该应用程序在WASCE环境中运行，并使用myfaces-1.2.6。

Answer 1

com.sun.faces。*是Mojarra而不是MyFaces。您应该尝试使用org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION。

JSF MyFaces：监视numberOfViewsInSession和numberOfLogicalViews
