spring mvc3.2.4 页面跳转没有显示 400 请求报错
Spring MVC 3.2.4 action 跳转到 jsp 页面时，页面无法显示， 在 firebug 中能看到请求，但是页面就是没有跳转。而且还有一个奇怪的问题出现了。下面开始详细介绍：
先把基本代码交代一下：先是login.jsp, 然后是ajax验证表单，然后提交到 action 然后 跳转到指定页面(这一步总是失败)

@ResponseBody
@RequestMapping(value="check")
public String check(@RequestParam("name")String uname, @RequestParam("pass")String pwd, HttpSession session) {
if ("".equals(uname) || "".equals(pwd)) {
if ("".equals(uname)) return "登录名不得为空！";
else if ("".equals(pwd)) return "密码不得为空！";
}
User u = userService.getByUname(uname);
String flag = "";
if (u == null) {
flag = "该用户不存在！";
} else if (!pwd.equals(u.getPwd())) {
flag = "登录名或密码错误！";
}
return flag;
}
页面跳转
**【1】首先，是直接返回jsp页面 ---------------> return "****";
@RequestMapping(value="login", method=RequestMethod.POST)
public String login(@RequestParam("name")String uname, @RequestParam("pass")String pwd, HttpSession session) {
User user = userService.getByUname(uname);
String rid = user.getRid();
session.setAttribute("rid", rid);
return "layout";
} 然后在firefox中查看结果，就如下图：
最后那个本地json请求和 home_page 请求有时候能成功，但是有时又如上图一直在请求中。
【2】 返回字符串"redirect:/test/layout.do"
@RequestMapping(value="login", method=RequestMethod.POST)
public String login(@RequestParam("name")String uname, @RequestParam("pass")String pwd, HttpSession session) {
User user = userService.getByUname(uname);
String rid = user.getRid();
session.setAttribute("rid", rid);
return "redirect:/test/layout.do";
} /test/layout.do
@RequestMapping(value = "layout")
public String layout() {
System.out.println("come into!");
return "layout";
} 然后，后台显示进入了这个action：
但是结果是：
然后，最后一个奇怪的问题出现了： 使用return new ModelAndView("redirect:/test/layout.do");时出错了
直接就进不去这个action了。。。。
真是一波未平一波又起 啊。
最后，谁能帮我解决跳转问题啊！谢谢了啊！~
