1、首先新建一个SpringBoot Maven 项目
2、配置相关规则
3、yml 文件
4、UploadService
5、UploadController
6、index.html 测试
7、查看测试结果

1、首先新建一个SpringBoot Maven 项目

pom 依赖如下

<!-- https://mvnrepository.com/artifact/com.github.tobato/fastdfs-client -->
<dependency>
    <groupId>com.github.tobato</groupId>
    <artifactId>fastdfs-client</artifactId>
    <version>1.26.7</version>
</dependency>

2、配置相关规则

/**
 * @ConfigurationProperties:用于读取yml文件或properties文件的值
 *  其他类可以通过@EnableConfigurationProperties直接加载
 *
 * @author wcong
 * @version 1.0
 * @date 2020-05-06 13:53
 */
@Data
@ConfigurationProperties(prefix = "upload")
@Component
public class UploadProperties {

    private String baseUrl;

    private List<String> allowTypes;

}

3、yml 文件

fdfs:
  so-timeout: 2500       # 读取时间
  connect-timeout: 600   # 连接超时时间
  thumb-image:           # 缩略图
    width: 100
    height: 100
  tracker-list:          # tracker 服务地址，可配置多个
    - 391.106.941.239:22122

upload:
  base-url: http://391.106.941.239:900/
  allow-types:          # miniTypes参考：https://www.w3school.com.cn/media/media_mimeref.asp
    - image/jpeg
    - image/png
    - image/bmp
    - image/gif

4、UploadService

/**
 * @author wcong
 * @version 1.0
 * @date 2020-05-06 14:15
 */
@Service
@Slf4j
@EnableConfigurationProperties(UploadProperties.class)
public class UploadService {


    @Autowired
    private FastFileStorageClient storageClient;

    @Autowired
    private UploadProperties uploadProperties;

    public String uploadImage(MultipartFile file) {
        // 1、校验文件类型
        String contentType = file.getContentType();
        if (!uploadProperties.getAllowTypes().contains(contentType)) {
            throw new RuntimeException("文件类型不支持");
        }
        // 2、校验文件内容
        try {
            BufferedImage image = ImageIO.read(file.getInputStream());
            if (image == null || image.getWidth() == 0 || image.getHeight() == 0) {
                throw new RuntimeException("上传文件有问题");
            }
        } catch (IOException e) {
            log.error("校验文件内容失败....{}", e);
            throw new RuntimeException("校验文件内容失败"+e.getMessage());
        }

        try {
            // 3、上传到FastDFS
            // 3.1、获取扩展名
            String extension = StringUtils.substringAfterLast(file.getOriginalFilename(), ".");
            // 3.2、上传
            StorePath storePath = storageClient.uploadFile(file.getInputStream(), file.getSize(), extension, null);
            // 返回路径
            return uploadProperties.getBaseUrl() + storePath.getFullPath();
        } catch (IOException e) {
            log.error("【文件上传】上传文件失败！....{}", e);
            throw  new RuntimeException("【文件上传】上传文件失败！"+e.getMessage());
        }
    }
}

5、UploadController

/**
 * @author wcong
 * @version 1.0
 * @date 2020-05-06 14:27
 */
@RestController
@RequestMapping("upload")
public class UpoadController {

    @Autowired
    private UploadService uploadService;

    @PostMapping("/doUpload")
    public Map<String,Object> doUpload(MultipartFile file){
        Map<String,Object> map = new HashMap<>();
        String filePath = uploadService.uploadImage(file);
        map.put("path",filePath);
        return map;
    }

}

6、index.html 测试

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>文件图片到fastDFS服务器</title>
</head>
<body>
    <h1>上传图片</h1>

    <form action="/upload/doUpload" method="post" enctype="multipart/form-data">
        <input type="file" name="file">
        <input type="submit" value="上传">
    </form>

</body>
</html>
