我的maven spring hibernate项目具有以下结构：

GP CONTROLES MODELES 服务 Web应用程序 JSP页面 WEB-INF 配置这是jsp文件的一部分

<form:form commandName="P" action="${pageContext.request.contextPath}/Controles/addPermanent.do" method="post">
   <td width="130" align="center"><form:input path="matPer"/></td>

这是我的控制器

@RequestMapping(value="/jsps/addPermanent")
 public String add(@ModelAttribute("P") Permanent permanent , BindingResult result){
        employe.AddEmploye(permanent);
        System.out.println("employe added successufully" );
        System.out.println("result has error"+ result.hasErrors());
     return "ListE";
 }

如果您有任何好的教程或者您遇到过这个问题，请告诉我原因是什么？帮我解决最好的祝福。
