Answer 1

例如，我创建了一个这样的login.html<div&nbsp;class="container"> &nbsp;&nbsp;&nbsp;&nbsp;<form&nbsp;method&nbsp;=&nbsp;"post"&nbsp;class="form-signin"&nbsp;role="form"&nbsp;action="LoginServlet"> &nbsp;&nbsp;&nbsp;&nbsp;<h2&nbsp;class="form-signin-heading">Please&nbsp;sign&nbsp;in</h2> &nbsp;&nbsp;&nbsp;&nbsp;<input&nbsp;type="text"&nbsp;class="form-control"&nbsp;name&nbsp;=&nbsp;"username"&nbsp;placeholder="User&nbsp;Name"&nbsp;required&nbsp;autofocus> &nbsp;&nbsp;&nbsp;&nbsp;<input&nbsp;type="password"&nbsp;class="form-control"&nbsp;name&nbsp;=&nbsp;"password"&nbsp;placeholder="Password"&nbsp;required> &nbsp;&nbsp;&nbsp;&nbsp;<div&nbsp;class="checkbox"> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<label> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input&nbsp;type="checkbox"&nbsp;value="remember-me">&nbsp;Remember&nbsp;me&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</label> &nbsp;&nbsp;&nbsp;&nbsp;</div> &nbsp;&nbsp;&nbsp;&nbsp;<input&nbsp;type="submit"&nbsp;class="btn&nbsp;btn-lg&nbsp;btn-primary&nbsp;btn-block"&nbsp;value="Sign&nbsp;in"> &nbsp;&nbsp;</form></div>在标签之间我通过将方法定义为“post”来调用LoginServlet。
