 （2）Ushenqing.jsp（修改的部分）

1<formaction="ApplyMeeting" class="templatemo-login-form"method="post" >

指提交数据后调用ApplyMeeting类中的doPost方法。

其中：method="post"表示按照post方法提交，action="ApplyMeeting "表示提交的数据交给ApplyMeeting.java。

2 <input name="no"type="text" class="form-control"id="inputFirstName" placeholder="会议编号">

<inputname="username" type="text" class="form-control"id="inputFirstName" placeholder="用户名">

<inputname="book" type="text" class="form-control"id="inputFirstName" placeholder="预定宾馆">

<inputname="content" type="text" class="form-control"id="inputFirstName" placeholder="发票内容">

<inputname="head" type="text" class="form-control"id="inputUsername" placeholder="发票抬头">

<inputname="remarks" type="text" class="form-control"id="inputUsername" placeholder="备注">

给输入文本框分别加name，用于ApplyMeeting.java中request.getParameter()方法获取文本框中的值。

3<button type="submit"class="templatemo-white-button" style=" font-size:18px">申请</button>

将按钮的类型设置为“submit”，表示提交数据。
