FastDFS的使用 (基本使用)

		//2 使用全局對象加載配置文件(暫時使用全文件名)
		ClientGlobal.init("E:/Eclipse/Graduation-Project/Graduation-Project/Graduation-manager-web/src/main/resources/FastDFS/fastdfsServer.conf");
		
		//3 建立TrackerClient對象
		TrackerClient trackerClient=new TrackerClient();
		
		//4 經過TrakcerClient對象來得到一個trackerServier對像
		TrackerServer trackerServer=trackerClient.getConnection();
		
		//5 建立一個StorageServier的引用，能夠是null
		StorageServer storageServer=null;
		
		//6 建立一個StorageClient,參數使用TrackerServer和StrorageServer
		StorageClient storageClient=new StorageClient(trackerServer, storageServer);
		
		//7 使用StorageClient上傳文件.
		String [] str=storageClient.upload_file("C:/Users/Public/Pictures/Sample Pictures/Chrysanthemum.jpg", "jpg", null);

封裝測試

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");

			System.out.println(name);
			
		} catch (Exception e) {
			// TODO Auto-generated catch block
