public class MatrixDetail {

    String header;
    int time;
    String detail;

//All getters and setters

 @RequestMapping(value = "/matrix/save", method = RequestMethod.POST)  
    public View saveMatrix(@ModelAttribute Metrix matrix, ModelMap model) {  
        System.out.println("Reachecd in matrix save" );
        return new RedirectView("/TrackerApplication/header.html");  
    }  

<form name="matrix" action="matrix/save.html" method="post">
    <table class="datatable" align:"center">

    <tr>
    <th>Login Id:</th>  <th> <input type="text" name="loginId" value= ${matrixList.loginId} required /> </th>

  <#list matrixList.headers as header>
    <spring:bind path = "MatrixDetail">
    <tr>
           <td> <input name = "header" value =  ${header.header} /> </td>
           <td> <input name = "time" value = ${header.time} /> </td>
           <td> <input name = "detail" value =  ${header.detail} /></td></tr>

我强烈建议不要这样做。

在某些情况下，表单可以在电子邮件中显示，但它们可能并不总是在电子邮件客户端中工作，更不用说那些只阅读纯文本形式电子邮件的人将无法使用它们。

如果您需要用户输入表单，请链接到站点上的一个页面，并将表单放在那里。
