在本機裝了一個msftpsrvr64模擬sftp，使用FlashFXP連接上傳都很正常用自己寫的測試就不行了
@Test
public void demo03(){
String dst = "\0000.zip";
String src = "D:\\0000.zip";
SftpUtil.uploadZip(dst, src, 6000);
}

調試過 是在session.connect()那里出的異常 debug進去看了一下 是連上了的 但是中間出了異常 沒看太懂...

TA貢獻1784條經驗 獲得超7個贊
是msftpsrvr64這個軟件的問題 換了一個freeSSHD模擬sftp服務器就好了
連接成功之后上傳文件的時候又報了如下異常：
3: Permission denied
問題原因：服務器的根目錄默認C盤
解決：修改服務器目錄到D：XXX 即可解決問題
