操作步骤

1、创建SpringBoot项目

2、修改pom.xml

<dependency>
    <groupId>com.github.tobato</groupId>
    <artifactId>fastdfs-client</artifactId>
    <version>1.26.7</version>
</dependency>

3、创建配置类UploadProperties。

package com.coydone.config;

import org.springframework.boot.context.properties.ConfigurationProperties;

import java.util.List;

@ConfigurationProperties(prefix = "upload")
public class UploadProperties {

    private String baseUrl;

    private List<String> allowTypes;

    public String getBaseUrl() {
        return baseUrl;
    }

    public void setBaseUrl(String baseUrl) {
        this.baseUrl = baseUrl;
    }

    public List<String> getAllowTypes() {
        return allowTypes;
    }

    public void setAllowTypes(List<String> allowTypes) {
        this.allowTypes = allowTypes;
    }
}

4、配置yaml

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服务配置地址列表
    - 116.62.44.5:22122
upload:
  base-url: http://116.62.44.5/
  allow-types:
    - image/jpeg
    - image/png
    - image/bmp
    - image/gif

5、创建UploadService。

@Component
@EnableConfigurationProperties(UploadProperties.class)
public class UploadService {
    private Log log= LogFactory.getLog(UploadService.class);

    @Autowired
    private FastFileStorageClient storageClient;

    @Autowired
    private UploadProperties prop;

    public String uploadImage(MultipartFile file) {
        // 1、校验文件类型
        String contentType = file.getContentType();
        if (!prop.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 prop.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());
        }
    }
}

6、创建UploadController。

@RestController
@RequestMapping("upload")
public class UploadController {
    @Autowired
    private UploadService uploadService;

    //上传
    @RequestMapping("doUpload")
    public Map<String,Object> doUpload(MultipartFile mf){
        System.out.println(mf.getOriginalFilename());
        Map<String, Object> map = uploadService.upload(mf);
        return map;
    }
}

7、创建static/index.html。

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
        <h1>文件上传</h1>
        <hr>
        <form action="/upload/doUpload" method="post" enctype="multipart/form-data">
            <input type="file" name="mf">
            <input type="submit" value="上传">
        </form>
    </body>
</html>

测试
