初始化日期控件

$(document).ready(function() {
	......
	$('#shouquanstart').datetimepicker({
		format: "YYYY-MM-DD HH:mm:ss",
		defaultDate:new Date()
	 });
	......
});

页面添加日期控件

<div class="form-group">
	<label class="col-sm-1 control-label">有效开始时间：</label>
	<div class="col-sm-5">
		<p class="input-group">
			<div class='input-group form_datetime' id='shouquanstart'>
				<input id="onsiteptw.ptwnum" name="onsiteptw.onsiteptw4gzxksqList[0].shouquanstart" type="text" maxlength="20" class="form-control"
				value="<fmt:formatDate value="${onsiteptwProcess.onsiteptw.onsiteptw4gzxksqList[0].shouquanstart}" pattern="yyyy-MM-dd HH:mm:ss"/>"/>
				<span class="input-group-addon">
					<span class="glyphicon glyphicon-calendar"></span>
				</span>
			</div>
		</p>
	</div>
</div>

后台对象

private Date shouquanstart;		// 开始时间
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
	@ExcelField(title="开始时间", align=2, sort=12)
	public Date getShouquanstart() {
	return shouquanstart;
}
public void setShouquanstart(Date shouquanstart) {
	this.shouquanstart = shouquanstart;
}

备注

JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")必须和页面的 pattern="yyyy-MM-dd HH:mm:ss"/>"/>一致
