FastDFS快速使用

                //加入配置文件 src/xnx3Config.xml  ，配置其FastDFS节点的参数。

                FastDFSUtil client=new FastDFSUtil();
                client.open();
                //上传
                UploadBean upload = client.upload("/jar_file/mysql-connector-java-3.0.17-ga-bin.jar");
                //下载
                boolean result=client.download("M00/07/65/CgAA-lVRp9-AYn-mAAPCLZlIvsE337.txt", "/Users/apple/Desktop/t/1.jar");
                client.close();
