java 操作代码：
private TrackerServer trackerServer;
    private StorageClient1 client;

    @Override
    public void afterPropertiesSet() throws Exception {
        String classPath = FdfsStorageServiceImpl.class.getClassLoader().getResource(".").getPath();
        ClientGlobal.init(classPath + File.separator + dfsConfig);

        TrackerClient tracker = new TrackerClient();  
        trackerServer = tracker.getConnection();  
        StorageServer storageServer = null;  
        client = new StorageClient1(trackerServer, storageServer);  
    }

    @Override
    public void destroy() throws Exception {
        trackerServer.close();  
    }

    @Override
    public String uploadFile(String content, String uploadFileName) {
        byte[] buffer = content.getBytes();
        ByteArrayInputStream inStream = new ByteArrayInputStream(buffer);
        return this.uploadFile(inStream, uploadFileName, buffer.length);
    }

FastDFS的TrackerClient和StorageClient对象是有状态的，需要调用方��
�证线程安全。
比如一个线程一个对象实例。

多线程任务，不可固定为线程创建TrackerClient和StorageClient，如
果是有状态的，需要提供一个连接池，类似数据库连接池缓��
�TrackerClient和StorageClient。避免每次重复创建。
