前端用form表单上传文件，但是加了enctype="multipart/form-data"之后报404，请求不对，去掉这个之后又可以将数据传到后台



<div id="addStudent" class="modal hide fade" tabindex="-1" role="dialog"

		aria-labelledby="myModalLabel" aria-hidden="true">

		<form class="bs-docs-example form-horizontal" method="post" action="${pageContext.request.contextPath}/student/addStudent"

		enctype="multipart/form-data">

			<div class="modal-header">

				<h3 align="center">添加学生信息</h3>

			</div>

			<div class="modal-body">

				<div class="control-group">

					<div class="controls">

						姓	名：<input type="text" placeholder="姓名" name="name" required="required"><br/>

						学	号：<input type="text" placeholder="学号" name="number" required="required" ><br/>

						身份证:<input type="text" placeholder="身份证" name="idCard" required="required" ><br/>

						请上传照片：<input type="file" placeholder="照片" name="photo" required="required" >

					</div>

				</div>

		<div class="modal-footer">

			<input id="save" type="submit" class="btn btn-primary" value="添加"/>

			<button class="btn" data-dismiss="modal" aria-hidden="true">取消</button>

		</div>
