JAVA上传FTP文件服务器

IFileService的实现类：

public class FileServiceImpl implements IFileService {
    private static Logger logger = LoggerFactory.getLogger(FileServiceImpl.class);

    @Override
    public String upload(MultipartFile file, String path) {
        // 原始名称
        String filename = file.getOriginalFilename();
        //扩展名
        String fileExtensionName = filename.substring(filename.lastIndexOf(".") + 1);
        //文件名
        String uploadFileName = UUID.randomUUID().toString() + "." + fileExtensionName;
        logger.info("开始上传文件，上传文件的文件名:{},上传的路径:{},新文件名:{}", filename, path, uploadFileName);

        File fileDir = new File(path);
        if (!fileDir.exists()) {
            fileDir.setWritable(true);
            fileDir.mkdirs();
        }
        // 新文件
        File targetFile = new File(path, uploadFileName);
        try {
            file.transferTo(targetFile);
            //上传文件到FTP服务器上
            FTPUtil.uploadFile(Lists.newArrayList(targetFile));
            //上传完成后，删除缓存中的文件。
            targetFile.delete();
        } catch (Exception e) {
            logger.error("图片上传失败",e);
            return null;
        }
        return targetFile.getName();
    }
}
