我刚刚开始使用Spring MVC开发SpringBoot Web应用程序。在我的POC中，我试图显示在上一页中选择的值。

登录屏幕运行正常。一旦单击了具有有效凭据的登录按钮，它就会按预期的那样重定向到success.jsp。现在我期望，当我在success.jsp中单击提交按钮时，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",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>

    </div>
</form:form>

success.jsp

<form:form action="/addDetails" method="post">
     <table>
      <tr>
      <td><form:label path = "name">Name : </form:label></td>

             <input type="text" name="name">
        </td>
      </tr>
      <tr>

           <td>
              <input type="radio" name="gender" value="male" > Male 
              <input type="radio" name="gender" value="female"> Female
              <input type="radio" name="gender" value="other"> Other
           </td>
        </tr>         
      <tr>
      <td>
              <input type = "submit" value = "Submit" name ="submit"/>
       </td>
       </tr>
