Java通过apache的common包操作ftp
场景：1.获取ftp列表
2.获取文件
实现：
private static void list() {
FTPClient ftpClient = new FTPClient();
try {
ftpClient.connect("ftp.someabcd.com", 21);
ftpClient.setControlEncoding("UTF-8");
ftpClient.login("anonymous", "anonymous@ftp.someabcd.com");
ftpClient.enterLocalPassiveMode();
ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);
FTPFile[] ftpFiles = ftpClient.listFiles("/");
for (FTPFile ftpFile : ftpFiles) {
System.out.println(ftpFile.getName());
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
ftpClient.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
}
}
get文件
private static void get() {
FTPClient ftpClient = new FTPClient();
OutputStream is =null;
try {
ftpClient.connect("ftp.someabcd.com", 21);
ftpClient.setControlEncoding("UTF-8");
ftpClient.login("anonymous", "anonymous@ftp.someabcd.com");
ftpClient.enterLocalPassiveMode();
ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);
File localFile = new File("G:\\a.txt");
is = new FileOutputStream(localFile);
ftpClient.retrieveFile("/temp/128.139.txt", is);
} catch (Exception e) {
e.printStackTrace();
} finally {
IOUtils.closeQuietly(is);
try {
ftpClient.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
}
}
其他常用操作：
ftpClient.dele(pathname);
ftpClient.deleteFile(pathname);
ftpClient.storeFile(remote, local);
