一、jar 包　

　　jar包下載：https://pan.baidu.com/s/1nwkAHU5 密碼：tlv6

　　或者

　　下載工程，安裝到 maven 本地倉庫

二、工具類代碼

package com.common.fastFDS;

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);
    }
    
    /**
     * 上傳文件方法
     * <p>Title: uploadFile</p>
     * <p>Description: </p>
     * @param fileName 文件全路徑
     * @param extName 文件擴展名，不包含（.）
     * @param metas 文件擴展信息
     * @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);
    }
    
    /**
     * 上傳文件方法
     * <p>Title: uploadFile</p>
     * <p>Description: </p>
     * @param fileContent 文件的內容，字節數組
     * @param extName 文件擴展名
     * @param metas 文件擴展信息
     * @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);
    }
}

三、測試代碼

@Test
public void testFastFDSClient() throws Exception
{
    //1.創建一個配置文件 client.conf (該文件名任意)
    //配置文件內容：tracker_server=192.168.**.**:22122 (你自己 FastDFS 服務器 ip+端口號)
    
    //2.創建 fastDFSClient 實例
    FastDFSClient fastDFSClient = new FastDFSClient("E:/workspaces/conf/client.conf");
    
    //3.執行圖片上傳,並返回圖片路徑
    String string = fastDFSClient.uploadFile("C:/waiguoren.jpg");
    System.out.println(string);
}
