执行到ftp.connect(ftpIP)进报的错,ftpIP是有值是IP+ ": "+端口
//FTP连接
public boolean connectFTP(){
try {
ftp = new FTPClient();
if(ftpPort.equals( " ")){
ftp.connect(ftpIP);
}
boolean blogin = ftp.login(ftpUser,ftpPassword);
if (!blogin) {
System.out.println( "FTP连接失败： "+ftpIP);
ftp.disconnect();
ftp = null;
return false;
}
return true;
} catch (Exception e) {
e.printStackTrace();
System.out.println( "FTP连接失败： "+ftpIP);
}
return false;
}
