Java客户端使用FastDFS上传文件

    环境的搭建可以参考,搭建的文章.

       在Java中使用fdfs上传文件

                1、添加相关的maven依赖

                            maven仓库中没有相关的jar包只能从github中去下载。

                            https://github.com/happyfish100/fastdfs-client-java

                            在eclipse中导入相关的maven工程,然后run -》maven-install
        在pom.xml文件中加入:


			org.csource
			fastdfs-client-java
			1.27-SNAPSHOT
		

                   2、Java代码

                    创建fdfs_client.properties配置文件,内容如下:
        tracker_server = 192.168.1.116:22122(其他的内容自行添加)

        代码:

public class FastDFS_Test {
	
	@Test
	public void uploadFile() throws Exception{
//		1、向工程中添加相关的依赖
//		2、创建一个配置文件,指向tracker的服务器的地址
//		3、加载配置文件
		ClientGlobal.init("/home/lxj/eclipse-workspace/taotao-mannger-web/src/main/resources/resource/fastdfs-client.properties");
//		4、创建一个tracker_client对象
		TrackerClient  trackerClient = new TrackerClient();
//		5、使用tracker_client对象获取tracker_server对象
		TrackerServer trackerServer = trackerClient.getConnection();
//		6、storageServer的引用,null就行
		StorageServer storageServer = null;
//		7、床架你一个storageClient对象,trackerserver和storageserver就行
		StorageClient client = new StorageClient(trackerServer, storageServer);
//		8、使用storageClient对象上传文件)(本地文件名,扩展名、元数据)
		String[] strs = client.upload_file("/home/lxj/桌面/mao.jpeg", "jpeg", null);
		for(String str:strs) {
			System.out.println(str);
		}
	}
}
	

                3、封装好的工具类:

package com.taotao.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;

public class FastDFSClient {

	private TrackerClient trackerClient = null;
	private TrackerServer trackerServer = null;
	private StorageServer storageServer = null;
	private StorageClient1 storageClient = null;
	
	public FastDFSClient(String conf) throws Exception {
		if (conf.contains("classpath:")) {
			conf = conf.replace("classpath:", this.getClass().getResource("/").getPath());
		}
		ClientGlobal.init(conf);
		trackerClient = new TrackerClient();
		trackerServer = trackerClient.getConnection();
		storageServer = null;
		storageClient = new StorageClient1(trackerServer, storageServer);
	}
