真的很奇怪，时不时的能行，不管服务器防火墙是开着还是关着都时不时能行，为什么呢 public static boolean uploadFile(String hostname, int port, String username,
String password, String pathname, String fileName, BufferedInputStream inputStream){
boolean flag = false;
FTPClient ftpClient = new FTPClient();
ftpClient.setControlEncoding("utf-8");
try{
ftpClient.connect(hostname, port); //连接ftp服务器
ftpClient.login(username, password); //登录ftp服务器
int replyCode = ftpClient.getReplyCode(); //是否成功登录服务器
System.out.println(replyCode);
if(!FTPReply.isPositiveCompletion(replyCode)){
System.out.println("disconnect");
}
ftpClient.setConnectTimeout(200*1000);
ftpClient.setBufferSize( 1024 );
ftpClient.makeDirectory(new String(pathname.getBytes("UTF-8"),"iso-8859-1"));
boolean flg = ftpClient.changeWorkingDirectory(pathname);
System.out.println("changedir"+flg);
ftpClient.setFileType(ftpClient.BINARY_FILE_TYPE);
ftpClient.enterLocalPassiveMode();//Switch to passive mode
boolean result = ftpClient.storeFile(fileName, inputStream);
System.out.println(result);
inputStream.close();
ftpClient.logout();
ftpClient.disconnect();
flag = true;
}catch (Exception e) {
e.printStackTrace();
}finally{
if(ftpClient.isConnected()){
try{
ftpClient.disconnect();
}catch(IOException e){
e.printStackTrace();
}
}
}
return true;
}
int replyCode = ftpClient.getReplyCode(); 每次尝试返回的都是230，连接ftp服务是成功的。
ftpClient.makeDirectory(new String(pathname.getBytes("UTF-8"),"iso-8859-1"));创建目录也是成功的，每次都行。
boolean result = ftpClient.storeFile(fileName, inputStream);上传文件这一步就时不时能行，不管服务器防火墙时不时开着的。
