求助：FTPClient.connect的时候异常[比较急， 要分我可以+]

Question

     String result = "上传处不成功";
     if(list != null){
            FTPClient ftpClient = new FTPClient(); 
            FileInputStream fis = null; 
            int reply = 0;
            try {          
                ftpClient.connect(loginInfo.getIP()); 
                ftpClient.login(loginInfo.getAccount(), loginInfo.getPassword()); 
                reply = ftpClient.getReplyCode();
                if (!FTPReply.isPositiveCompletion(reply)) {
ftpClient.disconnect();
System.out.println("FTP服务器 拒绝连接");
log.info("FTP服务器 拒绝连接");
return "FTP服务器 拒绝连接";
}                 
                String srcFilePath = CircuitExcel(loginInfo.getDestPath(), list, FileName, loginInfo.getExcelPath());
                String fileName = FileName.replace('/', '_')+".xls";
                File srcFile = new File(srcFilePath + fileName); 
                fis = new FileInputStream(srcFile); 
                //设置上传目录 
                ftpClient.changeWorkingDirectory(loginInfo.getDestPath()); 
                ftpClient.setBufferSize(1024); 
                ftpClient.setControlEncoding("GBK"); 
                //设置文件类型（二进制） 
                ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE); 
                ftpClient.enterLocalPassiveMode();
                ftpClient.storeFile(FileName+".xls", fis);  //--生成EXCEL文件
                result = "上传处成功";
            } catch (IOException e) {
             result = "FTP客户端出错！";
                e.printStackTrace(); 
                throw new RuntimeException("FTP客户端出错！", e); 
            } finally { 
                IOUtils.closeQuietly(fis); 
                try { 
                    ftpClient.disconnect(); 
                } catch (IOException e) { 
                 result = "关闭FTP连接发生异常！";
                    e.printStackTrace(); 
                    throw new RuntimeException("关闭FTP连接发生异常！", e); 
                } 
            }     
     }
     return result;ftpClient.connect(loginInfo.getIP()); 这里报错。已经肯定ip格式正确127.0.0.1本机测试的是XP系统， 有安装IIS, 读写等权限都有， 有设置开机密码， 本机电脑没杀毒软件防火墙等【裸奔】。 情景是这样的， 做一个WEBSERVICE接口，通过单号， 查询数据库【这里没错】， 然后生成EXCEL【这里也没错】， 上传到指定的FTP服务器上【这里错了】。异常如下：

Answer 1

不知道你用客户端工具或者不通过程序能连接上FTP服务器吗？

Answer 2

FTPClient client = new FTPClient();
client.connect(InetAddress.getLocalHost());
client.login("Test", "1234");
System.out.println(client.getReplyCode());我这样连我本机的没有问题。你把连接的那个变量换成我那种形式，然后测试下通不通。

Answer 3

我现在用的  没有问题的代码public boolean login(String host, int port, String user, String pwd)
throws Exception {
boolean flag = false;
try {
client.setControlEncoding("GBK");// 设置登陆编码格式
client.setConnectTimeout(60000);// 超时60秒
client.connect(host.trim(), port);// 连接FTP
int reply = client.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
this.close();
throw new Exception("FTP  refuse connect");
}
} catch (SocketException e) {
log.error(e);
throw new SocketException("FTP connect timeout");
} catch (IOException e) {
log.error(e);
throw new IOException("hostname/IP error");
}
...... }

Answer 4

FTPClient ftpClient = new FTPClient("127.0.0.1",port); 

Answer 5

client.setConnectTimeout(60000);// 超时60秒我只是没有设置超时， 所以本机没错， 别的FTP就异常了。^_^

Answer 6

不对吧，不设置超时是一直尝试连接不会超时的，你最好在连接的时候指定port。否则使用默认port可能会不成功。
