  • FastDFS简单入门小demo

    图片上传

    需要引入 FastDFS 相关的jar包,但是这个jar没有在中央仓库,所以还得需要找到这个jar手动安装到自己的本地仓库才能使用。

    需要一个配置文件   fdfs_client.conf

    需要一个 FastDFS 服务器

    看代码:

    fdfs_client.conf

    # connect timeout in seconds
    # default value is 30s
    connect_timeout=30
    
    # network timeout in seconds
    # default value is 30s
    network_timeout=60
    
    # the base path to store log files
    base_path=/home/fastdfs
    
    # tracker_server can ocur more than once, and tracker_server format is
    #  "host:port", host can be hostname or ip address
    tracker_server=192.168.25.133:22122    #服务器地址
    
    #standard log level as syslog, case insensitive, value list:
    ### emerg for emergency
    ### alert
    ### crit for critical
    ### error
    ### warn for warning
    ### notice
    ### info
    ### debug
    log_level=info
    
    # if use connection pool
    # default value is false
    # since V4.05
    use_connection_pool = false
    
    # connections whose the idle time exceeds this time will be closed
    # unit: second
    # default value is 3600
    # since V4.05
    connection_pool_max_idle_time = 3600
    
    # if load FastDFS parameters from tracker server
    # since V4.05
    # default value is false
    load_fdfs_parameters_from_tracker=false
    
    # if use storage ID instead of IP address
    # same as tracker.conf
    # valid only when load_fdfs_parameters_from_tracker is false
    # default value is false
    # since V4.05
    use_storage_id = false
    
    # specify storage ids filename, can use relative or absolute path
    # same as tracker.conf
    # valid only when load_fdfs_parameters_from_tracker is false
    # since V4.05
    storage_ids_filename = storage_ids.conf
    
    
    #HTTP settings
    http.tracker_server_port=80
    
    #use "#include" directive to include HTTP other settiongs
    ##include http.conf

        public static void main(String[] args) throws FileNotFoundException, IOException, Exception {
            // 1.加载配置文件
            ClientGlobal.init("D:\pinyougou_bigdata1\fastDFSdemo\src\main\resources\fdfs_client.conf");
            // 2.构建一个管理者客户端
            TrackerClient client=new TrackerClient();
            // 3.连接管理者服务端
            TrackerServer trackerServer = client.getConnection();
            //4. 声明存储服务端
            StorageServer storageServer=null;
            //5. 获取存储服务器的客户端对象
            StorageClient storageClient=new StorageClient(trackerServer, storageServer);
            //6.上传文件
            String[] strings = storageClient.upload_file("e:\image\b.jpg", "jpg", null);
            //7.显示上传结果 file_id
            for(String str:strings){
                System.out.println(str);
            }        
            
        }
