SpringBoot集成七牛云对象存储服务-摩杜云开发者社区

1.注册、登录七牛云

需要完成实名认证还能使用，实名认证后获取

accessKey（公钥）、secretKey（私钥）、bucket（新建的空间名称）、domain（外网访问的域名）

2.pom.xml中加入依赖

<!--集成七牛云对象存储服务-->
        <dependency>
            <groupId>com.qiniu</groupId>
            <artifactId>qiniu-java-sdk</artifactId>
            <version>7.7.0</version>
        </dependency>

        <dependency>

            <artifactId>gson</artifactId>
            <version>2.8.5</version>
        </dependency>

3.工具类

import com.qiniu.storage.UploadManager;
import com.qiniu.util.Auth;
import org.springframework.beans.factory.annotation.Value;

            SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");

            //3、获取文件名

            // String filename = datePath+"/"+ UUID.randomUUID().toString().replace("-", "")+ suffix;

            //4.构造一个带指定 Region 对象的配置类
            //Region.南(根据自己的对象空间的地址选
            Configuration cfg = new Configuration(Region.huanan());
            UploadManager uploadManager = new UploadManager(cfg);

            //5.获取七牛云提供的 token
            Auth auth = Auth.create(accessKey, secretKey);
            String upToken = auth.uploadToken(bucket);
            uploadManager.put(fileBytes, originalFilename, upToken);

            return domain + "/" +originalFilename;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }


}

4.接口调用

package com.wzz.controller;

import com.wzz.utils.QiniuKodoUtil;
import lombok.AllArgsConstructor;
import lombok.RequiredArgsConstructor;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

/**
 * @author xiaoss
 * @since 1.0, 2023年03月22日 14:17:14
 */
@RestController
@RequiredArgsConstructor
@RequestMapping("/upload")
public class UploadImage {

    private final QiniuKodoUtil qiniuKodoUtil;

    @GetMapping("/getImagePath")
    public String getImagePath(MultipartFile file){
        return qiniuKodoUtil.uploadImageQiniu(file);
    }
}
