静态服务JSF组件框架Javascript和CSS

| 我正在使用RichFaces 3.3.1，我试图找出是否有一种方法可以将RichFaces CSS和Javascript作为静态资源从其他Web服务器（如Apache或Nginx）托管。我尝试将web.xml中的“ 0”初始化参数设置为其他Web服务器，但是URI仍然相对于Web应用程序。我还尝试从RichFaces jar中提取两个Javascript文件 framework.pack.js ui.pack.js 在web.xml中添加了以下内容。

<context-param>
    <param-name>org.richfaces.LoadScriptStrategy</param-name>
    <param-value>NONE</param-value>
</context-param>

然后在xhtml中包含来自其他服务器的Javascript文件。不幸的是，在执行此操作之后，许多RichFaces组件均无法正常工作。还有其他想法可以做到这一点吗？有没有人在使用JSF组件框架方面取得任何成功？

我意识到这不是版本3.3中的答案，但是如果您可以升级到Richfaces 4 final，那么它们具有这个漂亮的小功能，可以将其添加到web.xml：

<context-param>
    <param-name>org.richfaces.staticResourceLocation</param-name>
    <param-value>#{resourceLocation}</param-value>
</context-param>

然后在META-INF中可以包含静态资源映射文件。完整路径/文件名是： META-INF / richfaces / static-resource-mappings.properties 其内容如下：

jquery.js=https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js
richfaces.js=https://mystaticimageserver.com/img/richfaces.js

编辑：我有时做的另一件事（在JSF 2中）只是取消了库提供程序包括的资源版本。然后，我只是创建一个静态版本，并将其自己包含在我的facelets模板中或在您的项目中有意义的任何地方。它虽然不太优雅，但是如果您组合资源以提高性能等，它会很好地工作。为此，我首先通过将其添加到faces-config.xml中，为脚本和样式表定义一些客户渲染器： faces-config.xml

<render-kit>
    <renderer>
        <component-family>javax.faces.Output</component-family>
        <renderer-type>javax.faces.resource.Script</renderer-type>
        <renderer-class>com.davemaple.jsf.resource.ScriptRenderer</renderer-class>
    </renderer>
    <renderer>
        <component-family>javax.faces.Output</component-family>
        <renderer-type>javax.faces.resource.Stylesheet</renderer-type>
        <renderer-class>com.davemaple.jsf.resource.StylesheetRenderer</renderer-class>
    </renderer>
</render-kit>

然后，将一些要抑制的文件或类添加到web.xml中： web.xml

<context-param>
    <param-name>com.davemaple.jsf.resource.suppressedScriptResourceClasses</param-name>
    <param-value></param-value>
</context-param>

<context-param>
    <param-name>com.davemaple.jsf.resource.suppressedScripts</param-name>
    <param-value>javax.faces:jsf.js :jquery.js :richfaces.js :richfaces-event.js :richfaces-base-component.js org.richfaces:message.js org.richfaces:richfaces-csv.js</param-value>
</context-param>
