如何通过FTP使用camel路由将所有文件从目录（包括子目录）移动到目标中没有子目录的特定目录？

Question

因为我对Apache-Camel非常陌生，所以我坚持使用一个用例。我希望使用camel路由实现将所有文件移动到目标中没有子目录的特定目录，

比如--

String src="ftp://username:password@host/srcDir/";
String destDir="ftp://username:password@host/destDir/";
fromUri = src+"?recursive=true&delete=true";
        
from(fromUri)
.to(destDir);

private void moveOverFTP(String from, String to) {
        FTPClient ftpClient = new FTPClient();
        try {
            URL url = new URL(from);
            String[] info = url.getUserInfo().split(":");

            ftpClient.connect(url.getHost());
            ftpClient.login(info[0], info[1]);

            String srcFolderPath = url.getPath();
            String targetFolder = new URL(to).getPath();
            move(srcFolderPath, targetFolder, ftpClient);
            
            ftpClient.logout();
        } catch (IOException e) {
            logger.error(e.getMessage(), e);
        }

    }
    
    private void move(String srcFolderPath, String targetFolder, FTPClient ftpClient) throws IOException {
        FTPFile[] files = ftpClient.listFiles(srcFolderPath);
        for (FTPFile file : files) {
            String fileName = file.getName();
            if (file.isDirectory()) {
                String tempSrcPath = srcFolderPath + fileName + "/";
                move(tempSrcPath, targetFolder, ftpClient);
                // delete empty directory
                ftpClient.removeDirectory(tempSrcPath);
            } else {
                System.out.println("Moving "+srcFolderPath + fileName +" to = "+ targetFolder);
                ftpClient.rename(srcFolderPath + fileName, targetFolder + fileName);
            }
        }
    }

任何帮助实现这一点，路线本身将不胜感激！提前感谢！

听起来您正在寻找的是flatten选项，即：

from(fromUri)
  .to(destDir + "?flatten=true");
