SpringBoot整合七牛云上传图片
准备工作1.注册并实名认证七牛云账号2.创建空间3.获取几个重要信息代码1.yml配置2.Service接口3.Service实现4.Controller层Swagger测试准备工作
1.注册并实名认证七牛云账号
不进行实名认证将不能创建空间，审核最多需要三个工作日，但通常实名认证过后1~2个小时就能收到认证成功的信息。
2.创建空间
3.获取几个重要信息
AK 和 SK 空间名称也就是创建空间时自己去的名字
临时域名
代码
1.yml配置
oss:qiniu:domain: qtxxxxxxxx.hn- # 访问域名(默认使用七牛云测试域名)accessKey: Gn0uwxxxxxxxxxxxxxxxxxxxxy3GEVmZqR58ed # 公钥 刚才的AKsecretKey: hs-ScVOxxxxxxxxxxxo0yG33uHm8_NkmnKy # 私钥 刚才的SKbucketName: officxxxxxxxxxxicture #存储空间名称
配置类
package studio.banner.officialwebsite.config;import lombok.Data;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Value;import org.ponent;/*** @Author: Re* @Date: /5/15 20:48*/@Data@Componentpublic class QiNiuYunConfig {/*** 七牛域名domain*/@Value("${oss.qiniu.domain}")private String qiniuDomain;/*** 七牛ACCESS_KEY*/@Value("${oss.qiniu.accessKey}")private String qiniuAccessKey;/*** 七牛SECRET_KEY*/@Value("${oss.qiniu.secretKey}")private String qiniuSecretKey;/*** 七牛空间名*/@Value("${oss.qiniu.bucketName}")private String qiniuBucketName;}
2.Service接口
package studio.banner.officialwebsite.service;import java.io.FileInputStream;/*** @Author: Re* @Date: /5/15 22:42*/public interface IQiNiuYunService {/*** 上传照片* @return* @param file* @param path*/String updatePhoto(String path, FileInputStream file);}
3.Service实现
package studio.banner.officialwebsite.service.Impl;import com.google.gson.Gson;import mon.QiniuException;import com.qiniu.http.Response;import com.qiniu.storage.Configuration;import com.qiniu.storage.Region;import com.qiniu.storage.UploadManager;import com.qiniu.storage.model.DefaultPutRet;import com.qiniu.util.Auth;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import studio.banner.officialwebsite.config.QiNiuYunConfig;import studio.banner.officialwebsite.service.IQiNiuYunService;import java.io.FileInputStream;/*** @Author: Re* @Date: /5/15 22:43*/@Servicepublic class QiNiuYunServiceImpl implements IQiNiuYunService {protected static Logger logger = LoggerFactory.getLogger(QiNiuYunServiceImpl.class);@AutowiredQiNiuYunConfig qiNiuYunConfig;@Overridepublic String updatePhoto(String key, FileInputStream file) {/*** 构造一个带指定Region对象的配置类*/Configuration cfg = new Configuration(Region.region2());/*** 其他参数参考类注释*/UploadManager uploadManager = new UploadManager(cfg);/*** 生成上传凭证，然后准备上传*/logger.info("密钥信息"+qiNiuYunConfig.getQiniuBucketName()+qiNiuYunConfig.getQiniuAccessKey()+qiNiuYunConfig.getQiniuSecretKey());Auth auth = Auth.create(qiNiuYunConfig.getQiniuAccessKey(), qiNiuYunConfig.getQiniuSecretKey());String upToken = auth.uploadToken(qiNiuYunConfig.getQiniuBucketName());try {Response response = uploadManager.put(file, key, upToken,null,null);//解析上传成功的结果DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);logger.info(putRet.key);logger.info(putRet.hash);} catch (QiniuException ex) {Response r = ex.response;logger.error(r.toString());try {logger.error(r.bodyString());} catch (QiniuException e) {r = e.response;logger.error(r.toString());}}return "http://"+qiNiuYunConfig.getQiniuDomain()+"/"+key;}}
4.Controller层
package studio.banner.officialwebsite.controller.background;import io.swagger.annotations.Api;import io.swagger.annotations.ApiOperation;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RequestPart;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.multipart.MultipartFile;import studio.banner.officialwebsite.service.IQiNiuYunService;import java.io.FileInputStream;import java.io.IOException;import java.util.UUID;/*** @Author: Re* @Date: /5/16 7:55*/@RestController@Api(tags = "上传图片接口",value = "UploadPhotoController")public class UploadPhotoController {@Autowiredprotected IQiNiuYunService qiNiuYunService;@PostMapping("/upload")@ApiOperation(value = "上传图片",notes = "上传图片不能为空",httpMethod = "POST")public String upload(@RequestPart MultipartFile file) {// 获取文件名String fileName = file.getOriginalFilename();// 生成随机的图片名String imgName = UUID.randomUUID() + "-" +fileName;if (!file.isEmpty()) {FileInputStream inputStream = null;try {inputStream = (FileInputStream) file.getInputStream();String path = qiNiuYunService.updatePhoto(imgName,inputStream);System.out.print("七牛云返回的图片链接:" + path);return path;} catch (IOException e) {e.printStackTrace();}return "上传失败";}return "上传失败";}}
