你好，波总:

试着用JFinal 做个模型，在Controll中进行文件下载，为什么方法执行2遍?

public void test(){

String cityName="全省";

String cityInst=getPara("cityInst");

System.out.println("haaaaaaaaaaaaaaaaaaaaaaaaaa!");

String path = RptCstmIncomeController.class.getClassLoader().getResource("").getFile()

+ "cstmserv/";

String xlsFilePath=path.substring(0,path.indexOf("WEB-INF"))+"cstm_report/excelFile/";

String report_temp = path + "RptCstmIncome.xls";

///renderText("hahaha!");

renderFile(new File(report_temp));

}

打印:

haaaaaaaaaaaaaaaaaaaaaaaaaa!
