Spring如何解析視圖？

Question

我在Spring 2.5.5下的View Resolution中遇到了一些麻煩。基本上我只是試圖用來自傳入的控制器的消息來顯示我的視圖。當Controller返回ModelAndView但DispatcherServelt說它無法找到Handler時，問題就出現了。

所有文件似乎都在正確的位置。我認爲問題在於Spring無法解決這個問題。從我看到的我正確使用InternalResourceResolver。我只是不知道爲什麼它失敗。

一旦我提出的要求，這是什麼在catalina.out的日誌：

Feb 8, 2010 3:27:24 PM com.madebymn.newsExample.web.IndexController handleRequest 
INFO: Handling a Request: /index.jsp 
Feb 8, 2010 3:27:24 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound 
WARNING: No mapping found for HTTP request with URI [/newsExample/WEB-INF/jsp/index.jsp] in DispatcherServlet with name 'catchAll' 

這裏是我的web.xml：

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 

<display-name>A News Example</display-name> 

<description>A News Example</description> 

<context-param> 
    <param-name>log4jConfigLocation</param-name> 
    <param-value>/WEB-INF/classes/log4j.properties</param-value> 
</context-param> 

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/applicationContext-jdbc.xml</param-value> 
</context-param> 

<listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener> 

<servlet> 
    <servlet-name>catchAll</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>catchAll</servlet-name> 
    <url-pattern>*.jsp</url-pattern> 
</servlet-mapping> 

<welcome-file-list> 
    <welcome-file>jsp/index.jsp</welcome-file> 
</welcome-file-list> 

這裏的Servlet的XML：

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

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> 
<bean name="indexController" class="com.madebymn.newsExample.web.IndexController" /> 
<bean name="authorController" class="com.madebymn.newsExample.web.AuthorController"> 
    <constructor-arg> 
     <ref bean="authorService" /> 
    </constructor-arg> 
</bean> 

<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> 
    <property name="mappings"> 
     <props> 
      <prop key="/index.jsp">indexController</prop> 
      <prop key="/author/*">authorController</prop> 
     </props> 
    </property> 
</bean> 

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> 
    <property name="prefix" value="/WEB-INF/jsp/" /> 
    <property name="suffix" value=".jsp" /> 
</bean> 

</beans> 

和h ERE的我的IndexController類：

public class IndexController implements org.springframework.web.servlet.mvc.Controller 
{ 
    protected final Log logger = LogFactory.getLog(getClass()); 

    @Override 
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
    { 
     logger.info("Handling a Request: " + request.getServletPath()); 

     ModelAndView modelAndView = new ModelAndView("index"); 
     modelAndView.addObject("message", "someMessage"); 

     return modelAndView; 
    } 
}

的問題是，你映射了DispatcherServlet爲*.jsp，當視圖的JSP了。嘗試將DispatcherServlet映射到不同的東西上，如*.html
