FastDFS图片服务器

首先要转一个FastDFS,这个很难装。一般由运维人员安装。

git项目fastdfs-client-java由happy fish开发的,down下来后import到项目中maven install到本地仓库即可

package com.common.utils;

import org.csource.common.NameValuePair;
import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient1;
import org.csource.fastdfs.StorageServer;
import org.csource.fastdfs.TrackerClient;
import org.csource.fastdfs.TrackerServer;
