我有運行在JBoss 7.1.1.Final之上的Primefaces 4.0。我使用谷歌webutilities（https://code.google.com/p/webutilities/）壓縮和結合我的JavaScript和CSS文件。當我在我的頁面上運行PageSpeed見解時，我的所有自定義css和js文件似乎都被壓縮，並且不會在頁面上輸出任何問題。但是，再次，所有Primefaces資源似乎都會跳過所有過濾器。這裏是我的webutilities配置：Primefaces 4.0資源壓縮

而且我已經嘗試設置以下參數web.xml中：
<context-param>

<param-value>false</param-value>
</context-param>
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Production</param-value>
</context-param>
但仍使用PageSpeed的輸出給了我下面如何讓頁面性能更好：
**Enable compression for the following resources to reduce their transfer size by 567.5KiB (75% reduction).**
Compressing http://localhost:8888/.../primefaces.js.xhtml?... could save 213.8KiB (79% reduction).

對我來說，看起來像Primefaces + Primefaces擴展資源的開銷很大。任何想法如何讓這些資源通過WebUtilities過濾器或至少啓用這些文件的壓縮？感謝幫助！
