本文展示了如何在Java应用中使用FastDFS进行文件下载（M00/00/57/JIWsB2SJgJWAQdavAAM-xxxxx.png）和图片上传，包括创建StorePath对象并处理异常。

	FastDFS整合部分省略......

在这里插入代码片

@Autowired
private FastFileStorageClient fastFileStorageClient;

@Override
public void testFastDFS() {
    FileOutputStream out = null;
    ByteArrayInputStream inputStream = null;
    try {

        StorePath storePath = new StorePath("group1", "M00/00/57/JIWsB2SJgJWAQdavAAM-xxxxx.png");
        byte[] bytes = fastFileStorageClient.downloadFile(storePath.getGroup(), storePath.getPath(), new DownloadByteArray());
        inputStream = new ByteArrayInputStream(bytes);
        StorePath storePathUpload = fastFileStorageClient.uploadImageAndCrtThumbImage( inputStream,
                inputStream.available(), "png", null);

    } catch (Exception e) {
        throw new RuntimeException(e);
    }finally {
        if(out != null ){
            try {
                out.close();
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }
        if(inputStream != null){
            try {
                inputStream.close();
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }
    }
}
