我对 Spring 3.1.0 有一个有趣的问题。JSP 页面没有评估其 EL。我已经调试了视图解析过程，并且正在使用 JstlView 并且检测到 Jstl 库。但是，我的 JSP 页面只是呈现如下内容
<%="Hello World!"%>
这里有很多关于这个问题的参考资料，但没有一个对我有用。
脚本标签未在 JSP 页面中呈现（使用 Spring + Tiles + JSPX） 未处理 Spring 和 JSP EL
从顶部开始，这是我的配置；

我正在使用 ContentNegotiatingViewResolver，因为我也有一些 freemarker 的东西和 REST。
控制器
@RequestMapping("/")
@Controller
public class RootResource extends AbstractResource {
...abridged...
@RequestMapping(value="/jsp", method = RequestMethod.GET, produces = "text/html")
public String getJSP(final Model m) {
return "example";
}
}
例子.jsp
<%@ page isScriptingEnabled="true" isELIgnored="false" %>
<html>
<head>
<title>Hello World JSP Page.</title>
</head>
<body>
<font size="10"><%="Hello World!"%></font>
</body>
</html>
我从控制器返回“example”作为视图名称，您可以在日志中看到它解析为正确的 WEB-INF/jsp/example.jsp
22:35:13,049 DEBUG [1168657208@qtp-1342126426-0] [org.springframework.web.servlet.view.ContentNegotiatingViewResolver] Returning [org.springframework.web.servlet.view.JstlView: name 'example'; URL [/WEB-INF/jsp/example.jsp]] based on requested media type 'text/html'
22:35:13,050 TRACE [1168657208@qtp-1342126426-0] [org.springframework.web.servlet.view.JstlView] Rendering view with name 'example' with model {} and static attributes {}

所以一切看起来都不错，只是 JSP 页面从未被正确评估。
example.jsp 看起来像这样
<%@ page isScriptingEnabled="true" isELIgnored="false" %> <%="Hello World!"%>
我正在使用 Maven jetty 6 插件来运行 webapp。
我确定我遗漏了一些简单的东西，这可能是那些“看得太久”的问题之一。
感谢您提供的任何指示。
更新 1 - 我刚刚将 Spring servlet 映射从 更改/*为/spring/*，现在它可以工作了。所以有一些关于spring servlet的细节被映射到/*我错过了。
