Jxls导出excel的若干方式总结（五）-- Simple Query

jdbc方式+ jx标签库（在excel中利用el表达式+sql语句）

注意：suplyArea后跟的是其对应查询结果集中字段名（或者别名）。

下面是excle模板中的内容：
<jx:forEach items="${rm.exec('select SUPPLYAREA_ID id,SUPPLYAREA_NAME name,X x,Y y,DATAGUID guid,STARTDATE sdate,ENDDATE edate,EDITUSER editor,LIFECYCLE life,REMARKS remarks from hsy_t_supplyarea order by SUPPLYAREA_ID DESC')}" var="suplyArea">
${suplyArea.id}|${suplyArea.name}|${suplyArea.editor}|${suplyArea.sdate}|
${suplyArea.edate}|${suplyArea.life}|${suplyArea.x}|${suplyArea.y}|
${suplyArea.guid}|${suplyArea.remarks}
</jx:forEach>

Sql语句如下：
select SUPPLYAREA_ID id,SUPPLYAREA_NAME name,X x,Y y,DATAGUID guid,STARTDATE sdate,ENDDATE edate,EDITUSER editor,LIFECYCLE life,REMARKS remarks from hsy_t_supplyarea order by SUPPLYAREA_ID DESC

java代码：
String templateDir = "D:/excel/template/SupplyAreaSQL.xls";
String targetDir="D:/excel/export/testSQL.xls";			
Map beans = new HashMap();
Class.forName("oracle.jdbc.driver.OracleDriver").getInterfaces();
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@168.9.202.49:1521:GIS", "JMJL","JMJL" );
ReportManager reportManager = new ReportManagerImpl(con,beans);
beans.put("rm", reportManager);
//关联模板	  
XLSTransformer transformer = new XLSTransformer();
transformer.transformXLS(templateDir, beans, targetDir);
