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

        //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
