SpringBoot整合腾讯云COS

一、参考项

腾讯云 COS(官网): 对象存储数据处理_COS数据处理_数据处理方案-腾讯云

COS SDK for Java(官网): 对象存储快速入门 - SDK 文档 - 文档中心 - 腾讯云

二、引入Pom文件

<!-- https://mvnrepository.com/artifact/com.qcloud/cos_api -->
<dependency><groupId>com.qcloud</groupId><artifactId>cos_api</artifactId><version>5.5.5</version><exclusions><exclusion><artifactId>slf4j-log4j12</artifactId><groupId>org.slf4j</groupId></exclusion></exclusions>
</dependency>

三、定义抽象类

public abstract class BaseObjectStorage {/*** 上传文件** @param pathAndName* @param file*/public abstract void upload(String pathAndName, File file);/*** 授权** @param pathAndName* @param time* @return*/public abstract String authorize(String pathAndName, long time);/*** 授权(路径全)** @param pathAndName* @param time* @return*/public abstract String authorizeAllName(String pathAndName, long time);/*** 临时上传文件授权** @param dir* @return*/public abstract Map<String, Object> tokens(String dir);/*** 删除文件** @param pathAndName*/public abstract void deleteFile(String pathAndName);}

四、COS实现类

package cn.xhh.xhh.core.objectstorage;import java.io.File;
import java.net.URL;
import java.util.Date;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import com.google.common.collect.Maps;
import com.qcloud.cos.COSClient;
import com.qcloud.cos.ClientConfig;
import com.qcloud.cos.auth.BasicCOSCredentials;
import com.qcloud.cos.auth.COSCredentials;
import com.qcloud.cos.auth.COSSigner;
import com.qcloud.cos.http.HttpMethodName;
import com.qcloud.cos.region.Region;
import lombok.Data;@Component
public class CosObjectStorage extends BaseObjectStorage {@Data@Component@ConfigurationProperties(prefix = "oss")public static class CosInfo {private String endpoint;private String accessKeyId;private String accessKeySecret;private String bucketName;private String region;private String rootDirectory;}@Autowiredprivate CosInfo cosInfo;private COSClient init() {COSCredentials cred = new BasicCOSCredentials(cosInfo.accessKeyId, cosInfo.accessKeySecret);Region region = new Region(cosInfo.getRegion());ClientConfig clientConfig = new ClientConfig(region);COSClient cosClient = new COSClient(cred, clientConfig);return cosClient;}@Overridepublic void upload(String pathAndName, File file) {COSClient cosClient = init();try {cosClient.putObject(cosInfo.bucketName, cosInfo.rootDirectory + pathAndName, file);} finally {cosClient.shutdown();}}@Overridepublic String authorize(String pathAndName, long time) {COSClient cosClient = init();try {Date expiration = new Date(new Date().getTime() + time);URL url = cosClient.generatePresignedUrl(cosInfo.bucketName,cosInfo.rootDirectory + pathAndName, expiration);return url.toString();} finally {cosClient.shutdown();}}@Overridepublic String authorizeAllName(String pathAndName, long time) {COSClient cosClient = init();try {Date expiration = new Date(new Date().getTime() + time);URL url = cosClient.generatePresignedUrl(cosInfo.bucketName, pathAndName, expiration);return url.toString();} finally {cosClient.shutdown();}}@Overridepublic Map<String, Object> tokens(String dir) {Map<String, Object> result = Maps.newHashMap();COSClient cosClient = init();try {long expireTime = 60;long expireEndTime = System.currentTimeMillis() + expireTime * 1000;Date expiration = new Date(expireEndTime);COSCredentials cred = new BasicCOSCredentials(cosInfo.accessKeyId, cosInfo.accessKeySecret);COSSigner signer = new COSSigner();dir = "frontend/xhh/" + dir;String sign = signer.buildAuthorizationStr(HttpMethodName.PUT, dir, cred, expiration);result.put("storeType", "cos");result.put("storageType", "cos");result.put("accessId", cosInfo.accessKeyId);result.put("signature", sign);result.put("expire", String.valueOf(expireEndTime / 1000));result.put("dir", dir);result.put("host", cosInfo.endpoint.split("://")[0] + "://" + cosInfo.bucketName + "."+ cosInfo.endpoint.split("://")[1]);} catch (Exception e) {e.printStackTrace();} finally {cosClient.shutdown();}return result;}@Overridepublic void deleteFile(String pathAndName) {COSClient cosClient = init();try {cosClient.deleteObject(cosInfo.bucketName, cosInfo.rootDirectory + pathAndName);} finally {cosClient.shutdown();}}}

五、application配置文件

objectstorage.type: cos
cos:endpoint: https://oss-cn-xhh.aliyuncs.comregion: 1access-key-id: LTAI4GKpXXXXXYuEzsyY63xaccess-key-secret: vsVyXXX8XYWOWYjFMPXXXXjkwbucket-name: dataroot-directory: xhh/export/
