Java操作fastDFS

一、加入Maven依赖

        <dependency>
            <groupId>org.csource</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27-SNAPSHOT</version>
        </dependency>

二、客户端代码

@RunWith(SpringRunner.class)
@SpringBootTest
public class GmallManageWebApplicationTests {
	@Test
	public void contextLoads() throws IOException, MyException {
		// 配置fdfs的全局链接地址
		String tracker = GmallManageWebApplicationTests.class.getResource("/tracker.conf").getPath();// 获得配置文件的路径
		ClientGlobal.init(tracker);
		TrackerClient trackerClient = new TrackerClient();
		// 获得一个trackerServer的实例
		TrackerServer trackerServer = trackerClient.getConnection();
		// 通过tracker获得一个Storage链接客户端
		StorageClient storageClient = new StorageClient(trackerServer,null);
		String[] uploadInfos = storageClient.upload_file("d:/a.jpg", "jpg", null);
		String url = "http://192.168.2.128";
		for (String uploadInfo : uploadInfos) {
			url += "/"+uploadInfo;
			//url = url + uploadInfo;
		}
		System.out.println(url);
	}
}

tracker.conf

tracker_server=192.168.2.128:22122
# 连接超时时间，针对socket套接字函数connect，默认为30秒
connect_timeout=30000
# 网络通讯超时时间，默认是60秒
network_timeout=60000

控制台打印：

http://192.168.2.128/group1/M00/00/00/wKgCgF2xkrOANCrrAAxpifD7458779.jpg

此路径在浏览器中访问即可访问我们上传的图片。

工具类

public class PmsUploadUtil {
    public static String uploadImage(MultipartFile multipartFile) {
        String imgUrl =  "http://192.168.2.128";
        // 上传图片到服务器
        // 配置fdfs的全局链接地址
        String tracker = PmsUploadUtil.class.getResource("/tracker.conf").getPath();// 获得配置文件的路径
        try {
            ClientGlobal.init(tracker);
        } catch (Exception e) {
            e.printStackTrace();
        }
        TrackerClient trackerClient = new TrackerClient();
        // 获得一个trackerServer的实例
        TrackerServer trackerServer = null;
        try {
            trackerServer = trackerClient.getConnection();
        } catch (IOException e) {
            e.printStackTrace();
        }
        // 通过tracker获得一个Storage链接客户端
        StorageClient storageClient = new StorageClient(trackerServer,null);
        try {
            byte[] bytes = multipartFile.getBytes();// 获得上传的二进制对象
            // 获得文件后缀名
            String originalFilename = multipartFile.getOriginalFilename();// a.jpg
            System.out.println(originalFilename);
            int i = originalFilename.lastIndexOf(".");
            String extName = originalFilename.substring(i+1);
            String[] uploadInfos = storageClient.upload_file(bytes, extName, null);
            for (String uploadInfo : uploadInfos) {
                imgUrl += "/"+uploadInfo;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return imgUrl;
    }
}

在springmvc文件上传控制器中我们只需要用MultipartFile multipartFile参数去接收就可以了。
