带有jsf2.0的Rich Faces 4.0

问题描述

我正在使用JSF 2.0和Rich Faces 4.0制作Web应用程序我想知道Web.xml中的最小入口是什么，并且面对config.xml，这样应用程序才能成功运行.声明Servlet的顺序很重要，因为我在运行带有自定义安全过滤器的应用程序时，Rich Faces组件有时无法呈现.能否请给我一个示例Web.xml文件.

I am making web app using JSF 2.0 and Rich Faces 4.0I want to know what should be minimum- entry in Web.xml and faces config.xml so that application will run successfully . Is order of servlet declaration matters , I am saying because when i am running my app with custom security filter, rich faces component is not rendering sometime . Can you please give me example Web.xml file.

* 感谢BalusC *

问题是当我添加安全过滤器时，Rich Faces组件未呈现?我感觉到我的web.xml条目和安全筛选器.你能告诉我我在这里做什么错了吗

*Thanks BalusC *

推荐答案

我在项目中遇到了同样的问题，因此我通过在验证中添加了加载Richfaces资源和jsf的路径来解决了这个问题.

I had the same issue in my project so I solved it by adding the path in the validation where the richfaces resources and jsf are being loaded.

类似这样的东西:

String uri = hr.getRequestURI();            
if (uri.endsWith(".view")
                && !uri.contains(ResourceHandler.RESOURCE_IDENTIFIER)
                && !uri.contains(ResourceHandlerImpl.RICHFACES_RESOURCE_IDENTIFIER)) {
            //You put your code here
}
