            <div class="clear"></div>
        </div>
    </div>
</div>
</body>
</html>


so above one is my code for jsp and below is the code of controller



    @RequestMapping(value={"/usermaster" }, method = RequestMethod.POST)
      public  final String addUserMaster(@ModelAttribute("CustomerForm") CustomerForm pricing, Map<String, Object> map,
                 Model model,  HttpServletRequest request) {
 System.out.println("the first name is "+pricing.getFirstname());
 System.out.println("the password is "+pricing.getPassword());
  return "usermaster";
           }

@RequestMapping(value={"/showusermaster" }, method = RequestMethod.GET)
      public String showPage(ModelMap model){
      model.addAttribute("CustomerForm", new CustomerForm());
      return "usermaster";
      }

但是我的页面使用带有url的弹出窗口打开了：

C:\Users\ganganshu.s\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\YW6383E8\usermaster

所以它应该像

一样打开

http://localhost:8080/enbee/usermaster

你能不能告诉我应该把什么放在表格动作中...因为我认为在弹簧MVC中的表单动作中存在一些错误我们把动作放在上面提到的情况中。

Spring confg文件如下：

    <mvc:interceptors> 
<bean class="com.enbee.admin.interceptor.AuthenticationInterceptor" />

<!-- Declare a view resolver-->
<bean id="jspViewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver"
    p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" p:order="1" />

并且jsp名称是usermaster.jsp

在sidemenu.jsp中我改为：

 <li><a href="<c:url value='/showusermaster'/>">User Master</a></li>

Answer 1

将method注释的RequestMapping参数更改为RequestMethod.POST：

@RequestMapping(value="/usermaster", method = RequestMethod.POST)
public final String addUserMaster(...){
...
}

因此，当您使用/usermaster将表单提交到网址method="POST"时，此方法将会执行。

您还需要有一个方法（映射到URL），该方法将向用户显示此页面。您可以使用以下方法：

@RequestMapping(value = "/showusermaster", method = RequestMethod.GET)
public String showPage(ModelMap model){
model.addAttribute("CustomerForm", new CustomerForm());
return "usermaster";
}

使用此方法，URL

http://localhost:8080/enbee/showusermaster

将向用户显示usermaster.jsp页面。现在，当您提交此form时，将调用上述addUserMaster方法。

您不必创建新的jsp文件。网址/showusermaster会将usermaster.jsp返回给用户，用户可以在其中添加表单值并提交表单：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
...
<c:url var="submitUrl" value="/usermaster">
<form:form id="form" action="${submitUrl}" modelAttribute="CustomerForm" method="POST">

现在，当用户点击提交按钮时，此表单将提交到/usermaster网址，并将由addUserMaster方法处理。

Answer 2

尝试指定控制器方法返回的内容类型，将produces = "text/html" param添加到@RequestMapping注释中。

无法返回到所需的URL或JSP视图
