Jxls导出excel的若干方式总结（四）-- jdbc方式(RowSetDynaClass)+ jx标签库

在excel中利用el表达式。注意：suplyArea后跟的是其对应数据库表的列名称。

List supply realist = saBiz.getSupplyAreaById(supplyAreaId);
SupplyArea sa = (SupplyArea) supplyAreaList.get(0);
Long id = sa.getSupplyAreaId();
String templateDir = "D:/excel/template/SupplyAreaIf.xls";
String targetDir="D:/excel/export/testIf.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" );
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
String query = "select SUPPLYAREA_ID,EDITUSER,SUPPLYAREA_NAME,X,Y," +	        		"REMARKS,STARTDATE,ENDDATE,LIFECYCLE,DATAGUID " +
	        		"from HSY_T_SUPPLYAREA ";	        
ResultSet rs = stmt.executeQuery(query);
RowSetDynaClass rsc = new RowSetDynaClass(rs,false);
beans.put("suplyArea",rsc.getRows());
XLSTransformer transformer = new XLSTransformer();
transformer.transformXLS(templateDir, beans, targetDir);
