Solution to the problem of garbled Chinese directory and file names uploaded by FTPClient in Java

Problem description:

When using org.apache.commons.net.ftp.FTPClient to create a Chinese directory and upload a Chinese file name, the Chinese in the directory name and file name is displayed as "??".

Reason:

In the FTP protocol, the file name encoding is iso-8859-1, so the directory name or file name needs to be transcoded.

Solution:

1. Convert the Chinese directory or file name to iso-8859-1 encoded characters. Reference code:

Copy code The code is as follows:

String name="Directory name or file name";

name=new String(name.getBytes("GBK"),"iso-8859-1");//The converted directory name or file name.

2. Set the linux environment variable

Copy code The code is as follows:

export LC_ALL= "zh_CN.GBK"
export LANG="zh_CN.GBK"

Example:

Copy code The code is as follows:

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)); tants.FTP_CLIENT_PASSWORD));
        ftpClient.setFileType(FTPClient .BINARY_FILE_TYPE);

                                                                                                                                                       "/");

                                                                                                                                                                             }

onepath=new String(onepath.getBytes("GBK"),"iso-8859-1");                   ftpClient.makeDirectory(onepath ;
ftpClient.storeFile(
new String(fileName.getBytes("GBK") . logout();
      }
                                                                                                            logout();
