SimpleUrlHandlerMapping 不与控制器映射（控制未到达控制器）答案

【问题标题】：SimpleUrlHandlerMapping do not map with controller (CONTROL IS NOT COMING TO THE CONTROLLER)SimpleUrlHandlerMapping 不与控制器映射（控制未到达控制器）
【发布时间】：2015-12-03 17:17:19
【问题描述】：

这里我使用 SimpleUrlHandlerMapping 的 urlMap 属性与控制器进行映射，但它不与控制器进行映射。这里我已经放置了调度程序、Jsp 和控制器的代码。

我已包含以下 Jar 文件--：

  com.springsource.org.apache.commons.fileupload-1.2.0.jar

    protected ModelAndView onSubmit(HttpServletRequest req,HttpServletResponse res,Object command)throws ServletException  //--OnSubmit Method Starts--//

        System.out.println("In controller");

        RegistrationBean regBean = (RegistrationBean) command;  

        String loginName=regBean.getLoginId();
        System.out.println("Name---->"+loginName);

【问题讨论】：

标签： java xml jsp

【解决方案1】：

试试这个：

 <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
           <property name="urlMap">
            <props>
               <prop key="/Registration.html">RegistrationCon</prop>
             </props>
           </property>
        </bean>

如果 URL 查找应始终使用当前 servlet 上下文中的完整路径，您可能需要设置：

<property name = "alwaysUseFullPath" value = "true" />

到 urlMapping bean

后期编辑： urlMap 使用这个，上面的代码是 mappings 的，对不起。

<property name="urlMap">
   <map>
       <entry key="/Registration.html" value-ref="RegistrationCon"/>
   </map>
  ...

仍然没有得到任何解决方案。
