将input改为select
改之前为input：
<div class="control-group">
<label class="control-label">班级：</label>
<div class="controls">
<form:input path="classid" htmlEscape="false" maxlength="64" class="input-xlarge "/>
</div>
</div>
改之后为：
<div class="control-group">
<label class="control-label">班级：</label>
<div class="controls">
<%--<form:input path="classid" htmlEscape="false" maxlength="64" class="input-xlarge "/>--%>
<form:select path="classid" class="input-medium"><%--path中的值为demoStudent的属性classid--%>
<form:option value="" label=""/>
<form:options items="${classes}" itemLabel="className" itemValue="classId" htmlEscape="false"/>
<%---items="${classes}"中classes为后台传过来的域中的值-%>
<%--itemLabel="className"的值对应表单中的显示值 option中的name--%>
<%--itemValue="classId"的值对应表单中的后台传入值 option中的value--%>
</form:select>
</div>
</div>
