这里如果连接报错,或者登陆失败,我感觉都该把异常抛出去,老师觉得呢。
private boolean connectServer(String ip,int port,String user,String pwd){
boolean isSuccess = false;
ftpClient = new FTPClient();
try {
ftpClient.connect(ip);
isSuccess = ftpClient.login(user,pwd);
} catch (IOException e) {
logger.error("连接FTP服务器异常",e);
}
return isSuccess;
}
