一、環境準備

• 騰訊云云儲存
• 建立一個儲存桶

二、匯入maven工程依賴

<!-- 騰訊雲儲存 -->
<dependency>
    <groupId>com.qcloud</groupId>
    <artifactId>cos_api</artifactId>
    <version>5.2.4</version>
</dependency>
<dependency>
    <groupId>com.qcloud</groupId>
    <artifactId>qcloud-java-sdk</artifactId>
    <version>2.0.1</version>
</dependency>
<!--multipartfile轉換file-->
<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.5</version>
</dependency>
 

三、配置檔案

qcloud:
  appID: 125725xxx
  secretId: AKID*********1y5PovTq
  secretKey: L6m*******4FG8pM
  bucketName: shw-****-1257256
  region: ap-beijing

四、書寫工具類

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.model.PutObjectRequest;
import com.qcloud.cos.region.Region;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import java.io.File;

@Component
public class QCloudUtil {

    @Value("${qcloud.appID}")
    private Long appID;
    
    @Value("${qcloud.secretId}")
    private String secretId;
    
    @Value("${qcloud.secretKey}")
    private String secretKey;
    
    @Value("${qcloud.bucketName}")
    private String bucketName;
    
    @Value("${qcloud.region}")
    private String region;

    /**
     * 上傳檔案到騰訊雲
     * @return
     */
    public String uploadFile(File file,String key){
        COSCredentials cred = new BasicCOSCredentials(secretId,secretKey);
        // 設定bucket的區域, COS地域的簡稱請參照
        ClientConfig clientConfig = new ClientConfig(new Region(region));
        //生成cos客戶端
        COSClient cosClient = new COSClient(cred, clientConfig);
        // 簡單檔案上傳, 最大支援 5 GB, 適用於小檔案上傳, 建議 20 M 以下的檔案使用該介面
        // 大檔案上傳請參照 API 文件高階 API 上傳
        // 指定要上傳到 COS 上的路徑
        
        PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, key, file);
        cosClient.putObject(putObjectRequest);
        cosClient.shutdown();
        String url="https://"+bucketName+".cos."+region+".myqcloud.com/"+key;
        return url;
    }
}
