Java中FTPClient上传中文目录、中文文件名乱码问题解决方法

问题描述:

  使用org.apache.commons.net.ftp.FTPClient创建中文目录、上传中文文件名时,目录名及文件名中的中文显示为“??”。

原因:

  FTP协议里面,规定文件名编码为iso-8859-1,所以目录名或文件名需要转码。

解决方案:

1.将中文的目录或文件名转为iso-8859-1编码的字符。参考代码:


   String name="目录名或文件名";

   name=new String(name.getBytes("GBK"),"iso-8859-1");// 转换后的目录名或文件名。


2.设置linux环境变量

export LC_ALL="zh_CN.GBK"

export LANG="zh_CN.GBK"


实例:

    public boolean upLoadFile(File file, String path, String fileName) throws IOException {

        boolean result = false;

        FTPClient ftpClient = new FTPClient();

        try {

            ftpClient.connect(confService.getConfValue(PortalConfContants.FTP_CLIENT_HOST));

            ftpClient.login(confService.getConfValue(PortalConfContants.FTP_CLIENT_USERNAME), confService

                    .getConfValue(PortalConfContants.FTP_CLIENT_PASSWORD));

            ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);

            // make directory             if (path != null && !"".equals(path.trim())) {                 String[] pathes = path.split("/");                 for (String onepath : pathes) {                     if (onepath == null || "".equals(onepath.trim())) {                         continue;                     }

                    onepath=new String(onepath.getBytes("GBK"),"iso-8859-1");                                        if (!ftpClient.changeWorkingDirectory(onepath)) {                         ftpClient.makeDirectory(onepath);                         ftpClient.changeWorkingDirectory(onepath);                     }                 }             }

            result = ftpClient.storeFile(new String(fileName.getBytes("GBK"),"iso-8859-1"), new FileInputStream(file));         } catch (Exception e) {             e.printStackTrace();         } finally {             ftpClient.logout();         }         return result;     }
