FastDFS的使用

FastDFS安装(http://blog.csdn.net/LoveCarpenter/article/details/75913329)

FastDFS的使用 (基本使用)

tracker_server=192.168.36.20:22122

package FastDFS;

import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient;
import org.csource.fastdfs.StorageServer;
import org.csource.fastdfs.TrackerClient;
import org.csource.fastdfs.TrackerServer;
import org.junit.Test;

public class FastDFSTest {

	/**
	 * 测试图片服务器是否能使用
	 */
	@Test
	public void testFastDFS() throws Exception{
		//1 建立一个配置文件,文件名任意，内容就是tracker服务器的地址
		
		//2 使用全局对象加载配置文件(暂时使用全文件名)
		ClientGlobal.init("E:/Eclipse/Graduation-Project/Graduation-Project/Graduation-manager-web/src/main/resources/FastDFS/fastdfsServer.conf");
		
		//3 建立TrackerClient对象
		TrackerClient trackerClient=new TrackerClient();
		
		//4 经过TrakcerClient对象来得到一个trackerServier对像
		TrackerServer trackerServer=trackerClient.getConnection();
		
		//5 建立一个StorageServier的引用，能够是null
		StorageServer storageServer=null;
		
		//6 建立一个StorageClient,参数使用TrackerServer和StrorageServer
		StorageClient storageClient=new StorageClient(trackerServer, storageServer);
		
		//7 使用StorageClient上传文件.
		String [] str=storageClient.upload_file("C:/Users/Public/Pictures/Sample Pictures/Chrysanthemum.jpg", "jpg", null);
	
		for(String string_name:str){
			System.out.println(string_name);
		}
	}
}

对上述步骤进行封装

package com.shi.util;

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);
	}
	
	/**
	 * 上传文件方法
	 * <p>Title: uploadFile</p>
	 * <p>Description: </p>
	 * @param fileName 文件全路径
	 * @param extName 文件扩展名，不包含（.）
	 * @param metas 文件扩展信息
	 * @return
	 * @throws Exception
	 */
	public String uploadFile(String fileName, String extName, NameValuePair[] metas) throws Exception {
		String result = storageClient.upload_file1(fileName, extName, metas);
		return result;
	}
	
	public String uploadFile(String fileName) throws Exception {
		return uploadFile(fileName, null, null);
	}
	
	public String uploadFile(String fileName, String extName) throws Exception {
		return uploadFile(fileName, extName, null);
	}
	
	/**
	 * 上传文件方法
	 * <p>Title: uploadFile</p>
	 * <p>Description: </p>
	 * @param fileContent 文件的内容，字节数组
	 * @param extName 文件扩展名
	 * @param metas 文件扩展信息
	 * @return
	 * @throws Exception
	 */
	public String uploadFile(byte[] fileContent, String extName, NameValuePair[] metas) throws Exception {
		
		String result = storageClient.upload_file1(fileContent, extName, metas);
		return result;
	}
	
	public String uploadFile(byte[] fileContent) throws Exception {
		return uploadFile(fileContent, null, null);
	}
	
	public String uploadFile(byte[] fileContent, String extName) throws Exception {
		return uploadFile(fileContent, extName, null);
	}
}

封装测试

package test;

import org.junit.Test;

import com.shi.util.FastDFSClient;

public class FastDFSClientTest {

	@Test
	public void testFastDFSClien(){
		try {
			FastDFSClient fastDFSClient =new FastDFSClient("E:/Eclipse/Graduation-Project/Graduation-Project/Graduation-manager-web/src/main/resources/FastDFS/fastdfsServer.conf");
			String name=fastDFSClient.uploadFile("C:/Users/Public/Pictures/Sample Pictures/Chrysanthemum.jpg" ,"jpg");
			System.out.println(name);
			
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}
