Question

java导出excel路径选择提示框或相对路径

public void execute() throws Exception {
String txtPath = "e://test//";
File file = new File(txtPath);
if (!file.exists()){
file.mkdirs();
}
String[] listHead = new String[] {"商户名称","分公司","地址","商户编号","终端号","是否在用"};
String[] listField = new String[] {"merchantName","company","address","merchantNumber","posNumber","isInUse"};
String sheetName = "商户资料";
Date now = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmmss");// 可以方便地修改日期格式
String dt = dateFormat.format(now);
String errorPath = txtPath + dt + ".xls";
merchantList = merchantDao.findbyInput(sc);
exportService.doListToExcel(merchantList, listHead, listField, sheetName,
errorPath);
exportService.downloadFile(errorPath);
}
}
我这是写死的，求改成动态

Answer 1

把保存路径和写入内容传进去，public void execute(String expPaht,String[][] cons) throws Exception

追问

我这个代码可以生成excel但路径写死了，不明白你这俩个参数的意思
