连接FTP时报错,急救!!
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;
}
