我只是想尝试一下使用 Tomcat 6.0 的 JSF 2.0 (MyFaces 2.0)。我对 JSF 完全陌生。我只是test.jsf在应用程序根目录中放置了一个静态 xhtml。当请求 URL 时，StackOverflowError总是会抛出 a：

 java.lang.StackOverflowError
 at org.apache.catalina.core.ApplicationHttpRequest$AttributeNamesEnumerator.<init>(ApplicationHttpRequest.java:904)
 at org.apache.catalina.core.ApplicationHttpRequest.getAttributeNames(ApplicationHttpRequest.java:243)
 at org.apache.catalina.core.ApplicationHttpRequest$AttributeNamesEnumerator.<init>(ApplicationHttpRequest.java:905)
 at org.apache.catalina.core.ApplicationHttpRequest.getAttributeNames(ApplicationHttpRequest.java:243)
 at org.apache.catalina.core.ApplicationHttpRequest$AttributeNamesEnumerator.<init>(ApplicationHttpRequest.java:905)

（重复了很多次，但后来：）

我做错了什么？

HTTP servlet 请求期间表示 servlet/过滤器映射中的StackOverflowError无限递归。你的FacesServlet映射是怎样的？它应该被映射为监听一个url-pattern而不是*.jsf监听（这是初学者的常见错误）。否则它将递归地调用自己。实际文件应命名为. 您只需像在 URL 中那样调用它。请仔细查阅/参考 JSF 2.0书籍/教程/文档如何正确配置/使用 JSF。 *.xhtml*.xhtml*.jsf
