本文介绍了如何在Flex客户端应用中利用JXL库，在Java服务端生成Excel文件并设置日期、数字单元格格式的具体步骤和代码示例。
Flex端调用代码：
private function export():void
{
if (this.passVehicleList.length <= 0)
{
MessageDlg.confirm("数据为空，不能导出！", null);
return;
}
parentname=parentname.replace(" ","");//去除名称中空格
var startDate:Date = timeStart.appendTimevalue(dateStart.selectedDate);
var stopDate:Date = timeStop.appendTimevalue(dateStop.selectedDate)
var startTimes:String = MyStringUtil.datetimetoString(startDate);
var stopTimes:String = MyStringUtil.datetimetoString(stopDate);
var serarchstr:String = searchStr.text;
inputParams.getParam("parentid").value = parentid;
if(isOver){
inputParams.getParam("isover").value = "over";
}
var contentTitle:String = startTimes+"至"+stopTimes+parentname;
var reportName:String = parentname;
var variables:URLVariables=new URLVariables();
variables.parentid = parentid;
variables.startTime = startTimes;
variables.stopTime = stopTimes;
variables.serarchstr = serarchstr;
var coloumTitle:Array;
if(!isOver){
contentTitle=contentTitle+"日常报表";
reportName=reportName+"日常报表";
variables.isover = "";
coloumTitle = new Array("名称","牌号","时间","类型","自重","载重","货重","备注");
}else{
contentTitle=contentTitle+"超载报表";
reportName=reportName+"超载报表";
variables.isover = "over";
coloumTitle = new Array("名称","牌号","时间","车型","限重","载重","超载","车主","移动电话","备注");
}
variables.fileName=reportName+".xls";
variables.contentTitle=contentTitle;
variables.coloumTitle=coloumTitle;
var u:URLRequest=new URLRequest(MyStringUtil.getUrlPath(Application.application.loaderInfo.url) + '/rest/ProjectAction.action');
u.data=variables; //Pass the variables
u.method=URLRequestMethod.POST; //Don't forget that we need to send as POST
navigateToURL(u, "_self");
