在 Spring2,5 中找不到资源使用多动作控制器时出现 404 错误

Question

所有配置在代码中都是最正确的，但资源错位正在发生

请求 /student3.htm 从“simple.jsp”发送到“web.xml”，发送到“spring-servlet.xml”到 SimpleUrlHandlerMapping 请求 /student3.htm 使用 bean id=class3 映射到 multiactioncontroller具有 methodNameParameter 具有属性。

它连接到 PropertiesMethodNameResolver 类，其中它的属性是“映射”，将请求 /student3.htm 映射到 multiactioncontroller 扩展类中的“保存”命名方法，有“Multi.java”类。 然后 save 方法通过 /WEB-INF/jsp/multi.jsp 中的 InternalResourceViewResolver 返回 ModelAndView 作为 multi.jsp 的视图名称“multi”，以获取消息 multiactionsuccess。

               HTTP Status 404 - /student3.htm

            --------------------------------------------------------------------------------

            type Status report

            message /student3.htm

            description The requested resource (/student3.htm) is not available.

                 In WEB-INF/jsp folder "multi.jsp" is present

                 multiaction success.

Answer 1

     method - access specifies should be "public" by userdefined methods
            -returntype should be "ModelAndView,Map,void"

     In the above code retifications are

     In WebContent simple.jsp

       <a href="student3.htm" >save</a>
       <a href="student4.htm" >update</a>
       <a href="student5.htm" >delete</a>
       <a href="student6.htm" >select</a>

      In com.spring.controller package Multi.java is controller Class

      method access specifies should be public
      change multi1 to multi as successView in all methods

      After editing the code done this  is successfully executed.
