JSP<；形式动作="；邮政「&燃气轮机；不重定向到控制器，Spring MVC

我刚刚开始使用SpringMVC开发SpringBootWeb应用程序。在我的POC中，我试图显示上一页上选择的值

登录屏幕工作正常。单击具有有效凭据的登录按钮后，它将按预期重定向到success.jsp。现在，当我单击success.jsp中的提交按钮时，它将调用控制器方法[action1（）/action2（）]，并在控制台中打印消息

控制器类：

@RequestMapping(value = "login", method = RequestMethod.GET)
    public String init(Model model) {
        model.addAttribute("msg", "Please Enter Your Login Details");
        System.out.println("INIT ====");
        return "login.jsp";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String submit(Model model,
            @ModelAttribute("loginBean") LoginBean loginBean) {
        System.out.println("submit22 ====");
        if (loginBean != null && loginBean.getUserName() != null
                & loginBean.getPassword() != null) {
            if (loginBean.getUserName().equals("a")
                    && loginBean.getPassword().equals("a")) {
                model.addAttribute("msg", loginBean.getUserName());
                return "success.jsp";
            } else {
                model.addAttribute("error", "Invalid Details");
                return "login.jsp";
            }
        } else {
            model.addAttribute("error", "Please enter Details");
            return "login.jsp";
        }
    }

    @RequestMapping(value="/addDetails",params="submit",method=RequestMethod.GET)
    public void action1()
    {
        System.out.println("submit block called GET ");
    }

    @RequestMapping(value="/addDetails",params="submit",method=RequestMethod.POST)
    public void action2()
    {
        System.out.println("submit block called POST");
    }

login.jsp

<form:form name="submitForm" method="POST">

    <div align="center">
        <table>
            <tr>
                <td>User Name</td>
                <td><input type="text" name="userName" /></td>
            </tr>
            <tr>
                <td>Password</td>
                <td><input type="password" name="password" /></td>
            </tr>
            <tr>
                <td></td>
                <td><input type="submit" value="Submit" /></td>
            </tr>
        </table>
        <div style="color: red">${error}</div>

那么运行时出现了什么错误？请澄清控制台中没有错误。它只是没有重定向。您还可以告诉我应用程序名是否默认设置为上下文路径吗？或者必须在某个地方进行配置？如果没有配置，是否有问题？
