未评估Spring jsp页面

Question

我对Spring 3.1.0有一个有趣的问题。JSP页面没有评估它们的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。

未在JSP页面中呈现的脚本标签（使用Spring Tiles JSPX）Spring和JSP EL未被处理

从顶部看，这是我的配置；

我正在使用ContentNetraatingViewResolver，因为我有一些freemarker的东西和REST在那里。

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";
    }
}

example.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，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 {}

所以一切看起来都很好，只是JSP页面从来没有正确评估过。

实例jsp看起来像这样

<%@ page isScriptingEnabled="true" isELIgnored="false" %> <%="Hello World!"%>

我正在使用Maven jetty 6插件来运行这个webapp。

我肯定我错过了一些简单的东西，这可能是那些“看得太久”的问题之一。

感谢您提供的任何建议。

更新1-我刚刚将Spring servlet映射从/*更改为/Spring/*，现在它可以工作了。因此，关于映射到spring servlet的一些细节我错过了。

Answer 1

绝对是一个“看了太久”的案例。

Spring servlet需要是默认servlet。即映射到/而不是/*。

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>        
</servlet-mapping>
