fastdfs文件服务器-客户端实现

需要的依赖：

		
			org.csource
			fastdfs
			1.0.0
		

dfs的配置文件：

connect_timeout = 2000
network_timeout = 30000
charset = ISO8859-1
http.tracker_http_port = 8080
http.anti_steal_token = false
http.secret_key = FastDFS1234567890


tracker_server.length = 1
tracker_server1 = 182.92.105.142:22122

客户端client java：

package com.citic.gatz.service.impl;

import java.io.InputStream;
import java.net.InetSocketAddress;
import java.util.Properties;

import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient1;
import org.csource.fastdfs.StorageServer;
import org.csource.fastdfs.TrackerClient;
import org.csource.fastdfs.TrackerGroup;
import org.csource.fastdfs.TrackerServer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;

初始化配置文件的方式有两种：

1.直接使用ClientGlobal.init(file);初始化配置文件的方式

2.ClientGloabl.setXX();使用set参数注入的方式
