Spring jsp頁面未評估

Question

我對Spring 3.1.0有一個有趣的問題。 JSP頁面沒有對其EL進行評估。我調試了視圖解析過程，正在使用JstlView並檢測到Jstl庫。然而，我的JSP頁面只呈現之類的東西

<%="Hello World!"%> 

有很多關於這個問題，沒有一個爲我工作過的在這裏引用。

Script tags not rendered in JSP page (using Spring + Tiles + JSPX) Spring and JSP EL not being processed

從頂部，這裏是我的配置;

的web.xml

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    version="2.5">

我使用ContentNegotiatingViewResolver，因爲我有一些freemarker的東西和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"; 
    } 
} 

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> 

我回來「榜樣」作爲視圖名從我的控制器，你可以在它解析爲正確的日誌中看到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'

因此，一切看起來都不錯，只是JSP頁面從未被正確計算。

example.jsp看起來像這樣

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

我使用Maven的碼頭6插件運行web應用程序。

我確定我錯過了一些簡單的東西，它可能是那些「看着它太久」的問題之一。

謝謝你可以給的任何指針。

更新1 - 我只是改變了春天的servlet映射從/*到/spring/*和現在的作品。因此，Spring servlet的一些細節被映射到我錯過的/*。

Answer 1

絕對是一個「看着它太久」的例子。

spring servlet需要成爲默認的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>
