java_Web 实战05
本次我们逐一的分析每一个功能,首先对于查看个人信息的功能由于我们将数据存储在session中可以直接使用session中的数据所以不用访问在servlet,中访问数据库进行查询操作,可以直接在页面中进行处理

<%-- 顾客--%>
<c:if test="${sessionScope.type.equals(\"0\")}">
<p> 顾客ID ${shopper.userId} </p>
<p> 姓名 ${shopper.userName}</p>
<p> 性别
<c:if test="${sessionScope.shopper.sex.equals(\"0\")}">
女
</c:if>
<c:if test="${sessionScope.shopper.sex.equals(\"1\")}">
男
</c:if>
</p>
<p> 身份证号 ${shopper.idNumber} </p>
<p> 手机 ${shopper.phone}</p>
<p> 家庭住址 ${shopper.user} </p>
</c:if>
<%-- 经纪人--%>
<c:if test="${sessionScope.type.equals(\"1\")}">
查看个人信息
<p> 工号 ${agent.agentId} </p>
<p> 房产经纪人姓名 ${agent.agentName}</p>
<p> 家庭住址 ${agent.agentAddress} </p>
<p> 手机 ${agent.phone} </p>
</c:if>
</body>
</html>
如此可以成功的实现对于个人页面信息的展示
对于第二个功能个人密码的修改.我们首先要录入原来的密码和更改后的密码.然后我这里使用message的方式来实现就是在后端判断之后发送message到前端,最后实现提示前端页面修改的状态.
