复选框请求返回null

Question

复选框请求返回null但我不明白为什么。我认为一切都是正确的...... name正在发挥作用。

JAVA：

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

  //Fetch the data from the GeneralSetup Page
  String name = request.getParameter("name");
  Boolean hasProfile7 = "on".equalsIgnoreCase(request.getParameter("hasProfile7"));
  Boolean hasWebCSR = "on".equalsIgnoreCase(request.getParameter("hasWebCSR"));
  Boolean hasWebAdmin = "on".equalsIgnoreCase(request.getParameter("hasWebAdmin"));
  Boolean hasWebClient = "on".equalsIgnoreCase(request.getParameter("hasWebClient"));

HTML：

＆＃13;

＆＃13;

<form role="form" method="post" action="GeneralSetup" data-toggle="validator">
  <div class="panel-body">
    <div class="row">
      <div class="col-lg-6">
        <div class="form-group">

          <input class="form-control" name="name" id="environmentName" placeholder="Enter the environment name" data-error="Please, insert a valid name"

编辑：

但是这个复选框（在同一页面中）有效：

<div class="form-group">
  <div class="checkbox">
    <label>
      <input type="checkbox" value="Admin" name="user" data-error="Please, choose at least one user" required> Admin</label>
  </div>
  <div class="help-block with-errors"></div>
</div>
