SpringBoot集成FastDFS上传文件功能

上一篇文章，在服务器上安装了FastDFS

这一篇记录下在SpringBoot项目中添加使用FastDFS上传功能

1. pom文件添加依赖

<!-- https://mvnrepository.com/artifact/com.github.tobato/fastdfs-client -->
<dependency>
    <groupId>com.github.tobato</groupId>
    <artifactId>fastdfs-client</artifactId>
    <version>1.27.2</version>
</dependency>

2. application添加FastDFS配置信息

fdfs:
  # 连接超时时间
  connect-timeout: 30
  # 读取时间
  so-timeout: 30
  # tracker服务配置地址列表
  tracker-list: 192.168.10.235:22122

注意：tracker-list 填写的是 tracker 服务器的ip地址，不是 storage 服务器的ip

3. controller

@Autowired
public UploadService uploadService;

public String uploadFace(MultipartFile file) throws Exception {
	// 获取上传文件的名称
	String originalFilename = file.getOriginalFilename();
	if (StringUtils.isBlank(originalFilename)) {
	    return "文件不能为空，请选择一个文件再上传！";
	}
	String[] fileNameArr = originalFilename.split("\\.");
	// 文件后缀
	String suffix = fileNameArr[fileNameArr.length - 1];
	// 判断后缀是否符合
	if (!suffix.equalsIgnoreCase("png")
	        && !suffix.equalsIgnoreCase("jpg")
	        && !suffix.equalsIgnoreCase("jpeg")) {
	    return "文件图片格式不支持！";
	}
	String filePath = uploadService.uploadFastDfs(file, suffix);
	if (StringUtils.isBlank(filePath)) {
	    return "文件上传失败！";
	}
	return filePath;
}

4. service

public interface UploadService {

    /**
     * 使用FastDFS上传文件
     *
     * @param file        要上传的文件
     * @param fileExtName 文件扩展名
     * @return 文件路径
     * @throws IOException 文件上传异常
     */
    public String uploadFastDfs(MultipartFile file, String fileExtName) throws IOException;

}

@Service
public class UploadServiceImpl implements UploadService {

    @Autowired
    public FastFileStorageClient fastFileStorageClient;

    @Override
    public String uploadFastDfs(MultipartFile file, String fileExtName) throws IOException {
        StorePath storePath = fastFileStorageClient.uploadFile(file.getInputStream(),
                file.getSize(), fileExtName, null);
        return storePath.getFullPath();
    }
}
