今天完成的事：

1、换了一种更新的方式将昨天的问题解决了（jsp上更新按钮，传递id到控制器，控制器通过id获取信息传到view上，用户在view上更改信息并提交，控制器接受Student对象并更新）

2、将项目war包部署到服务器上（注册页面填完信息后提交404异常）

明天计划的事：查找问题解决今天的问题继续部署

遇到问题：

1、显示Student信息列表中create-at和update-at时间，将毫秒数转换成yyyy-MM-dd格式

网上比较简单且大多数的做法是这样：（但是不能解决问题）

<fmt:formatDate value="${student.create_at}" pattern="yyyy-MM-dd"></fmt:formatDate>
<fmt:formatDate value="${student.update_at}" pattern="yyyy-MM-dd"></fmt:formatDate>

<td><s:dateParam value="${student.create_at}" type="yyyy-MM-dd"></s:dateParam></td>
<td><s:dateParam value="${student.update_at}" type="yyyy-MM-dd"></s:dateParam></td>

整了蛮久后改成以下代码就好了

<jsp:useBean id="createTime" class="java.util.Date" scope="page"></jsp:useBean>
<jsp:setProperty property="time" name="createTime" value="${student.create_at}"/>
<td><fmt:formatDate value="${createTime}" pattern="yyyy-MM-dd" /></td>
<jsp:useBean id="updateTime" class="java.util.Date" scope="page"></jsp:useBean>
<jsp:setProperty property="time" name="updateTime" value="${student.update_at}"/>
<td><fmt:formatDate value="${updateTime}" pattern="yyyy-MM-dd" /></td>

2、连接到服务器端的mysql创建表提示：

后在配置文件中加上：max_allowed_packet=*m 解决

3、填完信息后提交出现404（不知所以。因为此项目在本地是没有问题的）
