我有一个基本问题。我是Spring MVC Web框架的初学者。当我单击jsp文件中的按钮时，我想从我的控制器类中调用一个方法。我已经尝试了所有可能的解决方案，但我还没有打电话给它。谢谢你的帮助。这是我的代码
/*Controller*/

答案 0 :(得分：1)
我认为使用"/user/success.htm"作为"input"表单的操作网址，可以配置ControllerClassNameHandlerMapping作为控制器映射处理程序。
因为当您放置"/success.htm"时，它实际上是使用您的ParameterizableViewController之一进行映射，而不是使用UserController的方法进行映射（使用/success.htm作为网址映射） 。假设您的DispatcherServlet已映射为"/"。

我没有在JSP中看到使用spring：url。这是使用Spring MVC编写url的经典方法，因为它会自动将基本URL添加到您的应用程序中。 你没有提到任何映射到你的控制器所以它将被触及root root url'/'，如果你想要达到你的方法'doActions（）'你必须使用：
<spring:url value="/success.htm" var="success"/>
然后：
<a href="${success}>toSuccess</a>
另外，你应该使用JSPX，而不是JSP页面，这是Spring MVC的推荐方式。
