检查validation ,出错输入框会变红色，
1.由<td><input type="password" name="password" class="form-control"/></td>
input 框改写为：
<td style="background-color: #f9f9f9;">原密码</td>
<td><form:input type="password" path="password" cssClass="form-control" cssErrorClass="form-control error" /></td>
<td style="background-color: #f9f9f9;">新密码</td>
<td><form:input type="password" path="passwordNew" cssClass="form-control" cssErrorClass="form-control error"/></td>
<td style="background-color: #f9f9f9;">密码确认</td>
<td><form:input type="password" path="passwordConfirm" cssClass="form-control" cssErrorClass="form-control error"/></td>
<td style="background-color: #f9f9f9;">终端价</td>
<td><form:input path="retailPrice" cssClass="form-control" cssErrorClass="form-control error" value="${distributorPriceForm.retailPrice}" /></td>
2.新建css文件夹-commom.css文件
.error {
background-color: red; }
3.添加颜色链接
<link href="css/common.css" rel="stylesheet">
4加红色的星：
<td style="background-color: #f9f9f9;">原密码<span style="color:red;">*</span></td>
5“取消”按钮的链接
<a href="initMenu" class="btn btn-danger">取消</a>
