fastdfs 文件系统增加自定义路径（M00,M01,N02...）

实现：自定义上传 M00/M01/M02 等路径

1.准备好 fdfs 服务，没有的话先搭建。点击这里

2.进入 storage 容器，修改配置文件/etc/fdfs/storage.conf（不同安装可能路径不一样）

# path(disk or mount point) count, default value is 1（挂载点数量，默认值为1）
store_path_count=2

# store_path#, based 0, if store_path0 not exists, it's value is base_path（如果store_path0不存在，将使用base_path路径）
# the paths must be exist （文件夹必须存在）
store_path0=/var/fdfs
store_path1=/var/fdfs/data2

这里修改 count 为 2 ， 下边增加 store_path1=/var/fdfs/data2

3.然后呢？然后就结束了

4.使用 java-sdk 怎么上传指定路径

    @Value("${fastdfs.tracker_servers}")
    public void setTrackerServers(String tracker_servers){
        try {
        	ClientGlobal.initByTrackers(tracker_servers);
        	trackerClient = new TrackerClient();
            trackerServer = trackerClient.getConnection();
        	log.info("FastDFS.ClientGlobal.initByTrackers");
        } catch (Exception e) {
            log.error("FastDFS Client Init Fail!",e);
        }
    }
   

    protected static TrackerClient trackerClient;
    protected static TrackerServer trackerServer;
    protected static StorageServer storageServer;
    protected static StorageClient storageClient;


    //文件上传
    public static String uploadFile(byte[] file_buff, String fileExtName) throws IOException, MyException {
    	
    	storageServer = trackerClient.getStoreStorage(trackerServer);
    	String storageIp = storageServer.getSocket().getInetAddress().getHostAddress();  
    	Integer port = storageServer.getSocket().getPort();  
        //这里的第三个参数就是指定路径下标的，0->M00->store_path0 , 1->M01->store_path1 ...
    	storageServer = new StorageServer(storageIp, port, 1);
 
        StorageClient1 client = new StorageClient1(trackerServer, storageServer);
        // 直接调用StorageClient对象方法上传文件即可。
        String fileName = client.upload_file1(file_buff, fileExtName, null);
        log.info("文件上传成功，路径为：{}" , fileName);
        return fileName;
    }

结果(到 M01 了)

INFO 48996 --- [           main] c.Y.common.util.dfs.FastDFSClientUtil    : 文件上传成功，路径为：group1/M01/03/82/T489ul8IJ9OAHG8BAABmIZYby_8670.jpg

5.下次更新上传给指定 group 的文章..
