表单提交不能在后端使用 Spring MVC 间歇性地处理 IE [英] Form Submit Not working on IE intermittently with Spring MVC in backend

问题描述

我在jsp文件上有一个简单的表单:

I have a simple form on jsp file :

<form:form method="POST" class="my-form" id="dummyExtDelSubmitForm" name="dummyExtDELSubmitForm"   action="/my-web/landingPage/showPage">               
 <input type="text" name="viewName" value="userRegistrationPage" >              
 <input type="submit" name="submitDummYForm" value="Submit" ></input>               
</form:form>

在 Spring MVC 控制器上我有以下方法:

on Spring MVC Controller I have the below method :

@RequestMapping(value = "/showPage", method = RequestMethod.POST)
public ModelAndView redirectToPage(@ModelAttribute("baseUserVO") BaseUserVO baseUserVO, HttpServletRequest request,Model model) throws BrownApplicationException {

 HttpSession session = request.getSession();

 if (baseUserVO != null && baseUserVO.getViewName()!=null) {
       return new ModelAndView("redirect:" + viewName, CommonConstants.MODEL, model);
     else{
       return new ModelAndView("redirect:/landingPage/home.brd", CommonConstants.MODEL, model);
 }
}

问题是当我提交表单时，有时会填充 BaseUserVO 对象，而大多数时候不会.它在 Firefox 上运行良好，没有失败.我试图在 fiddler 中查看请求，在表单中向 showPage 提交请求，我看不到参数，如果 viewName 不存在，则按照逻辑，然后重定向到 landPage/home ，在稍后的重定向中我做查看 viewName 参数.

Problem is when I submit the form , the BaseUserVO object is populated sometimes and most of the time it is not. it works fine on Firefox without fail. I tried to see the request in fiddler , in the form submit request to showPage , i don't see the parameters going , as per the logic if the viewName is not present, then redierect to landingPage/home , in the later redirection I do see the viewName parameter.

BaseUserVO 的代码，它只是一个 POJO:

Code for BaseUserVO which is just a POJO :

public class BaseUserVO {
    private Integer userMasterId;
    private String firstname;
    private String lastname;
    private Integer relationshipCode;
    private String relationshipName;
    private String userName;
    private String userDisplayName;
    private String viewName;
    private String wpoId;
    private String userType;

    public Integer getUserMasterId() {
        return userMasterId;
    }
... getter seetter for other attributes.

不知道是服务器端的问题还是客户端的问题，如果有线索请回复.

Not sure whether it's a problem from Server side or client, Please reply if any clue.

推荐答案

发现问题，它和 IE 有自动认证问题(见下面链接)，虽然目前没有具体的解决方案但有一些解决方法.

Found the issue , its and IE with automatic authentication issue (see below Link), although no concrete solution so far but there are some workarounds.
