我在java应用程序中工作，我正在使用ftp发送文件。 但是当我发送20-30文件时，它的show异常即连接未打开 并且文件不发送可以任何人帮助我。我用来上传文件的cade在
之下public void uploadtxtFile(collectinfo myobj,String localFileFullName, String fileName, String hostDir)
throws Exception {
FTPClient ftpclient= DBConnection.connect();
File file = new File(localFileFullName);
if (!(file.isDirectory())) {
if (file.exists()) {
FileInputStream input = null;
BufferedInputStream bis=null;
try {
input = new FileInputStream(new File(localFileFullName));
if (input != null) {
hostDir = hostDir.replaceAll("//", "/");
logger.info("uploading host dir : " + hostDir);
boolean bool =false ;
logger.error("Replay of the ftp store file is 1111"+ ftpclient.getReplyCode());
try{
ftpclient.setBufferSize(1048576);
ftpclient.enterLocalPassiveMode();
logger.error("Replay of the ftp store file is 2222"+ ftpclient.getReplyCode());
if( ftpclient.isConnected()){
// here server timeout error is get
logger.error("here server timeout error is get");//new
bis = new BufferedInputStream(input);
logger.error("Replay of the ftp store file is 3333"+ ftpclient.getReplyCode());
bool = ftpclient.storeFile(hostDir, bis);
} else{
logger.error("here server timeout error is get");//new
bis = new BufferedInputStream(input);
logger.error("Replay of the ftp store file is 6666"+ ftpclient.getReplyCode());
ftpclient.enterLocalPassiveMode();
bool = ftpclient.storeFile(hostDir, bis);
}}finally{
bis.close();
input.close();
}
logger.error("Replay of the ftp store file is 4444 "+ ftpclient.getReplyCode());
if (bool) {
logger.info("Success uploading file on host dir :"+hostDir);
} else {
logger.error("file not uploaded.");
BackgroundService.pendingQueue.add(myobj);
}
} else {
logger.error("uploading file input null.");
}
} catch(Exception ex)
{
logger.error("Error in connection ="+ex);
BackgroundService.pendingQueue.add(myobj);
}finally {
ftpclient.logout();
ftpclient.disconnect();
}
} else {
logger.info("uploading file is not exists.");
}
}
}
进入该DBConnection是一个返回FTPclient obj
的类
