springboot整合七牛云实例

整合步骤

1. 引入依赖

   
       com.qiniu
       qiniu-java-sdk
       7.3.0
   

    

2. 配置七牛云参数

   qiniu.accessKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
   qiniu.secretKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
   qiniu.bucket=XXXXXXX
   qiniu.zone=XXXXXXX
   qiniu.domain=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

   import com.qiniu.common.Zone;
   import com.qiniu.storage.BucketManager;
   import com.qiniu.storage.UploadManager;
   import com.qiniu.util.Auth;
   import org.springframework.beans.factory.annotation.Value;
   import org.springframework.context.annotation.Bean;
   import org.springframework.context.annotation.Configuration;
   
   @Configuration
   public class QiniuConfig {
       /**
        * 华东机房,配置自己空间所在的区域
        */
       @Bean
       public com.qiniu.storage.Configuration qiniuConfig() {
           return new com.qiniu.storage.Configuration(Zone.zone2());
       }
   
       /**
        * 构建一个七牛上传工具实例
        */
       @Bean
       public UploadManager uploadManager() {
           return new UploadManager(qiniuConfig());
       }
   
       @Value("${qiniu.accessKey}")
       private String accessKey;
       @Value("${qiniu.secretKey}")
       private String secretKey;
   
       /**
        * 认证信息实例
        * @return
        */
       @Bean
       public Auth auth() {
           return Auth.create(accessKey, secretKey);
       }
   
       /**
        * 构建七牛空间管理实例
        */
       @Bean
       public BucketManager bucketManager() {
           return new BucketManager(auth(), qiniuConfig());
       }
   }

    

3. 编写七牛云工具类

   import com.qiniu.common.QiniuException;
   import com.qiniu.http.Response;
   import com.qiniu.storage.BucketManager;
   import com.qiniu.storage.UploadManager;
   import com.qiniu.util.Auth;
   import com.qiniu.util.StringMap;
   
   import java.io.File;
   import java.io.IOException;
   import java.io.InputStream;
   import java.util.Properties;
   
   public class QiniuUtil {
   
       private static UploadManager uploadManager;
       private static BucketManager bucketManager;
       private static Auth auth;
       private static String bucket;
       private static String domain;
       private static StringMap putPolicy;
   
       static {
           uploadManager = SpringUtil.getBean(UploadManager.class);
           bucketManager = SpringUtil.getBean(BucketManager.class);
           auth = SpringUtil.getBean(Auth.class);
           try {
               InputStream stream=Thread.currentThread().getContextClassLoader().getResourceAsStream("application.properties");
               Properties p=new Properties();
               p.load(stream);
               bucket = p.get("qiniu.bucket").toString() ;
               domain = p.get("qiniu.domain").toString() ;
           } catch (IOException e) {
           }
       }
   
       /**
        * 上传文件
        * @param file
        * @param fileName
        * @return
        * @throws QiniuException
        */
       public static String uploadFile(File file, String fileName) throws QiniuException {
           Response response = uploadManager.put(file, fileName, getUploadToken());
           int retry = 0;
           while (response.needRetry() && retry < 3) {
               response = uploadManager.put(file, fileName, getUploadToken());
               retry++;
           }
           if (response.statusCode == 200) {
               return "http://" + domain + "/" + fileName;
           }
           return "上传失败!";
       }
   
       /**
        * 删除文件
        * @param key
        * @return
        * @throws QiniuException
        */
       public static String delete(String key) throws QiniuException {
           Response response = bucketManager.delete(bucket, key);
           int retry = 0;
           while (response.needRetry() && retry++ < 3) {
               response = bucketManager.delete(bucket, key);
           }
           return response.statusCode == 200 ? "删除成功!" : "删除失败!";
       }
   
       /**
        * 获取上传凭证
        */
       private static String getUploadToken() {
           return auth.uploadToken(bucket, null, 3600, putPolicy);
       }
   }

    

4. 调用工具类
