springboot 整合 ftps

• 導入jar 

<!-- FTPS -->
<dependency>
    <groupId>commons-net</groupId>
    <artifactId>commons-net</artifactId>
    <version>3.3</version>
</dependency>

 

• 編寫工具類

public class FtpsUtils {

    private FTPSClient ftpsClient;

    public FtpsUtils(String host, int port, String userName, String passWord) {
        ftpsClient = this.ftpConnection(host, port, userName, passWord);
    }

    private FTPSClient ftpConnection(String host, int port, String userName, String passWord) {
        FTPSClient ftpClient = null;
        try {
            ftpClient = new FTPSClient("TLS", false);
            ftpClient.connect(host, port);
            ftpClient.login(userName, passWord);
            //設置上傳目錄
            ftpClient.changeWorkingDirectory(ftpDir);
            //設置文件爲 2進制
            ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
            ftpClient.setDataTimeout(18000);
            ftpClient.execPROT("P");
            // 設置被動模式
            ftpClient.enterLocalPassiveMode();
        } catch (Exception e) {
        }
        return ftpClient;
    }

    //測試
    public static void main(String[] args) throws Exception{
        FtpsUtils ftpsUtils = new FtpsUtils("ftps.geotmt.com",21,"dp_yingxiao","6AjsMUih");
        FTPSClient ftpsClient = ftpsUtils.ftpsClient;
        FTPFile[] ftpFiles = ftpsClient.listFiles();
        System.out.println(ftpFiles);
    }

}

// 不設置藍色部分，ftp 列表展示不出來
