请告诉我为什么我会得到那个例外？任何帮助都是值得的。提前谢谢

问候,，

您需要向web.xml添加上下文加载侦听器：

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


上下文配置位置
/WEB-INF/yourApplicationContext.xml

听众：

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


org.springframework.web.context.ContextLoaderListener

您使用的是哪个版本的Spring MVC？使用源代码检查堆栈跟踪。如果使用Maven，IDE应该能够将堆栈跟踪行与jar源代码链接起来。

首先尝试清理服务器。如果这没有帮助，那么请发布您的web.xml以及您使用的tomcat版本。添加了一些代码。现在请您检查一下。但是我的应用程序到目前为止不需要ApplicationContext.xml。还有一个教程在我的机器上运行良好。下面是链接：从堆栈跟踪来看，它似乎是需要ContextLoaderListener的SpringJSP标记。你刚开始使用标签库吗？这里也有同样的问题。当我使用SpringJSP标记表单时，我遇到了这个错误。没有它，我不会有任何错误。请注意，我在应用程序中设置了app-servlet.xml和ContextLoaderListener。

    @Controller
@SessionAttributes
public class LogonController  {

    @RequestMapping(value="/profile/addlogon", method = RequestMethod.POST)
    public String addlogon(@ModelAttribute("userlogon") UserLogon userlogon, BindingResult result){

        String user=userlogon.getUsername();
        String user1=userlogon.getPassword();
            return "redirect:logon.jsp";
        }

@RequestMapping(value="/profile/logon", method = RequestMethod.GET)
public ModelAndView handalRequestInternal(HttpServletRequest req,HttpServletResponse res)
{

    System.out.println("I am in controller");
    return new ModelAndView("logon", "command", new UserLogon());

}
