我試圖表明這些CSV文件的URL,但我失敗了
我如何能得到URL在我的文件系統中的文件創建網址是什麼?
public DownloadFileResponse downloadFile(DownloadFileRequest req) {
//TODO: create and set ImportMarketResponse object and return the following as response data
// "EventSet Id: " + req.eventSetId;
String txt ="EventSet Id: " + req.eventSetId;
DownloadFileResponse res = new DownloadFileResponse();
res.setReturnDate(txt);
return res;
}
