檢查validation ,出錯輸入框會變紅色，

1.由<td><input type="password" name="password" class="form-control"/></td>

input 框改寫爲：

<td style="background-color: #f9f9f9;">原密碼</td>
<td><form:input type="password" path="password" cssClass="form-control" cssErrorClass="form-control error" /></td>
<td style="background-color: #f9f9f9;">新密碼</td>
<td><form:input type="password" path="passwordNew"  cssClass="form-control" cssErrorClass="form-control  error"/></td>
<td style="background-color: #f9f9f9;">密碼確認</td>
<td><form:input type="password" path="passwordConfirm"  cssClass="form-control"  cssErrorClass="form-control error"/></td>
<td style="background-color: #f9f9f9;">終端價</td>						
<td><form:input path="retailPrice" cssClass="form-control" cssErrorClass="form-control error" value="${distributorPriceForm.retailPrice}" /></td>

2.新建css文件夾-commom.css文件

.error {

background-color: red;  }

3.添加顏色連接

 <link href="css/common.css" rel="stylesheet">

4加紅色的星：

<td style="background-color: #f9f9f9;">原密碼<span style="color:red;">*</span></td>

5「取消」按鈕的連接

 <a href="initMenu" class="btn btn-danger">取消</a>
