1. 把FastDFS提供的jar包新增到工程中
2. 初始化全域性配置。載入一個配置檔案。
3. 建立一個TrackerClient物件。
4. 建立一個TrackerServer物件。
5. 宣告一個StorageServer物件，null。
6. 獲得StorageClient物件。
7. 直接呼叫StorageClient物件方法上傳檔案即可。

測試一、text測試

@Test
	publicvoidtestUpload() throws Exception {
		// 1、把FastDFS提供的jar包新增到工程中
		// 2、初始化全域性配置。載入一個配置檔案。
		ClientGlobal.init("D:\\workspaces\\xiafei-manager\\xiafei-manager-web\\src\\main\\resources\\properties\\client.conf");
		// 3、建立一個TrackerClient物件。
		TrackerClient trackerClient = new TrackerClient();
		// 4、建立一個TrackerServer物件。
		TrackerServer trackerServer = trackerClient.getConnection();
		// 5、宣告一個StorageServer物件，null。
		StorageServer storageServer = null;
		// 6、獲得StorageClient物件。
		StorageClient storageClient = new StorageClient(trackerServer, storageServer);
		// 7、直接呼叫StorageClient物件方法上傳檔案即可。
		String[] strings = storageClient.upload_file("D:\\Documents\\Pictures\\images\\2f2eb938943d.jpg", "jpg", null);
		for (String string : strings) {
			System.out.println(string);
		}
	}
 

Client.conf

tracker_server=192.168.198.129:22122

測試二：建立工具類實現上傳

1、書寫工具類

package com.yunhe.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;

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:")) {
	    	System.out.println("before conf======"+conf);
	        conf = conf.replace("classpath:", this.getClass().getResource("/").getPath());
	        System.out.println("after conf======"+conf);
	    }
	    ClientGlobal.init(conf);
	    trackerClient = new TrackerClient();
	    trackerServer = trackerClient.getConnection();
	    storageServer = null;
	    storageClient = new StorageClient1(trackerServer,   storageServer);
	}

	/**
	* 上傳檔案方法
	* <p>Title: uploadFile</p>
	* <p>Description: </p>
	* @param fileName 檔案全路徑
	* @param extName 副檔名，不包含（.）
	* @param metas 檔案擴充套件資訊
	* @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);
	}

	/**
	* 上傳檔案方法
	* <p>Title: uploadFile</p>
	* <p>Description: </p>
	* @param fileContent 檔案的內容，位元組陣列
	* @param extName 副檔名
	* @param metas 檔案擴充套件資訊
	* @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);
	 }
	}
 

2、呼叫工具類

@Test
	publicvoid testFastDfsClient() throws Exception {
		FastDFSClientclient = newFastDFSClient("D:\\workspaces\\xiafei-manager\\xiafei-manager-web\\src\\main\\resources\\properties\\client.conf");
		String uploadFile = client.uploadFile("D:\\Documents\\Pictures\\images\\200811281555127886.jpg", "jpg");
		System.out.println(uploadFile);
	}
