Springboot集成FastDFS

pom配置：

<dependency>
   <groupId>com.github.tobato</groupId>
   <artifactId>fastdfs-client</artifactId>
   <version>1.26.2</version>
</dependency>

yml配置：

fdfs:
  soTimeout: 1500 #socket连接超时时长
  connectTimeout: 600 #连接tracker服务器超时时长
  resHost: 192.168.5.129
  storagePort: 8889
  thumbImage: #缩略图生成参数，可选
    width: 150
    height: 150
  trackerList: #TrackerList参数,支持多个，我这里只有一个，如果有多个在下方加- x.x.x.x:port
    - 192.168.5.129:22122

注意：我这里存储服务端口用的8889，一般为8888

配置文件:

@Component
public class AppConfig {
    @Value("${fdfs.resHost}")
    private String resHost;

    @Value("${fdfs.storagePort}")
    private String storagePort;

    public String getResHost() {
        return resHost;
    }

    public void setResHost(String resHost) {
        this.resHost = resHost;
    }

    public String getStoragePort() {
        return storagePort;
    }

    public void setStoragePort(String storagePort) {
        this.storagePort = storagePort;
    }
}

@Configuration
@Import(FdfsClientConfig.class)
// 解决jmx重复注册bean的问题
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
public class FastClientImporter {
}

文件操作工具类:

@Slf4j
@Component
public class FastDFSClientWrapper {

    @Autowired
    private FastFileStorageClient storageClient;

    @Autowired
    private AppConfig appConfig;   // 项目参数配置

    /**
     * 上传文件
     * @param file 文件对象
     * @return 文件访问地址
     * @throws IOException
     */
    public String uploadFile(MultipartFile file) throws IOException {
        StorePath storePath = storageClient.uploadFile(file.getInputStream(),file.getSize(), FilenameUtils.getExtension(file.getOriginalFilename()),null);
        return getResAccessUrl(storePath);
    }

    /**
     * 将一段字符串生成一个文件上传
     * @param content 文件内容
     * @param fileExtension
     * @return
     */
    public String uploadFile(String content, String fileExtension) {
        byte[] buff = content.getBytes(Charset.forName("UTF-8"));
        ByteArrayInputStream stream = new ByteArrayInputStream(buff);
        StorePath storePath = storageClient.uploadFile(stream,buff.length, fileExtension,null);
        return getResAccessUrl(storePath);
    }

    // 封装图片完整URL地址
    private String getResAccessUrl(StorePath storePath) {
        String fileUrl = "http://" + appConfig.getResHost()
                + ":" + appConfig.getStoragePort() + "/" + storePath.getFullPath();
        return fileUrl;
    }

    /**
     * 删除文件
     * @param fileUrl 文件访问地址
     * @return
     */
    public void deleteFile(String fileUrl) {
        if (StringUtils.isEmpty(fileUrl)) {
            return;
        }
        try {
            StorePath storePath = StorePath.praseFromUrl(fileUrl);
            storageClient.deleteFile(storePath.getGroup(), storePath.getPath());
        } catch (FdfsUnsupportStorePathException e) {
            log.warn(e.getMessage());
        }
    }
}

测试Controller：

@RestController
public class FastDFSController {
    @Autowired
    private FastDFSClientWrapper dfsClient;

    @PostMapping("/files-anon/fdfsupload")
    public String upload(@RequestParam("file") MultipartFile file) throws Exception {
        String imgUrl = dfsClient.uploadFile(file);
        return imgUrl;
    }
}

经过Postman访问该API,得到正确的返回结果

在浏览器中访问该图片

基本操作已经成功完成了，该图片也被存储到了多台文件服务器中。
