Question

.java code and .jsp code are in the picture

绝对uri：[http://www.springframework.org/tags/form]不能在web.xml或与此应用程序一起部署的jar文件中解析

在图片中可以看到.java代码和.jsp代码。也许存在一些错误： form：form action =“ processForm” modelAttribute =“ student” 在学生表单中.jsp和 theModel.addAttribute（“ student”，theStudent）; 在StudentController.java中

替换您的

@RequestMapping ("/processForm")

与此：

@RequestMapping ("/processForm", method=RequestMethod.POST)

并分享输出/结果。

processForm选择的默认方法是GET，而不是POST。

更新

如果链接的帮助对您不利，请尝试添加学生进行建模。

public String processForm(@ModelAttribute ("student") Student theStudent, Model model)

model.addAttribute("student", theStudent);

当我使用modelAttribute =“ student”时，如何解决“ HTTP状态500 –内部服务器错误”
