<div class="control-group">    <label class="control-label visible-ie8 visible-ie9">Username</label>        <div class="controls">            <div class="input-icon left">                <i class="icon-user"></i>                <input class="m-wrap placeholder-no-fix" type="text" placeholder="Username" name="userName"/>            </div>        </div></div>

这里的input标签的name为userName，需要与Model层中的类属性对应上。之后我们在controller中使用getParameter方法取得userName即可。代码如下：

@RequestMapping(value="/login", method={RequestMethod.POST})public String login(AdminUser adminUser, HttpServletRequest request, HttpServletResponse response) {//      request.getParameter("userName");        System.out.println(request.getParameter("userName"));        MyResponse mr = new MyResponse();        System.out.println(adminUser.toString());        return "login_success";}
