当我点击这个链接时，它应该会得到map to studentdetails控件showForm方法，显示另一个studentdetails.jsp，但我得到的是404。最重要的是，你没有找到

<mvc:annotation-driven />

浏览器会根据您的主机地址发出请求。所以如果你的主机IP是

127.0.0.1

然后将向

127.0.0.1/studentDetails

但你似乎有一个上下文路径

<Context path="/studentspringmvc"

<a href="${pageContext.request.contextPath}/studentDetails">Click here</a>
