今天來整合一下SpringBoot和阿里雲OSS對象存儲服務。
一、配置OSS服務
先在阿里雲開通對象存儲服務,拿到AccessKeyId、AccessKeySecret。
創建你的bucket(存儲空間),相當於一個一個的文件夾目錄。按業務需求分類存儲你的文件,圖片,音頻,app包等等。創建bucket是要選擇該bucket的權限,私有,公共讀,公共讀寫,按需求選擇。創建bucket時對應的endpoint要記住,上傳文件需要用到。
可以配置bucket的生命週期,比如說某些文件有過期時間的,可以配置一下。
二、代碼實現
引入依賴包
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>
<version>2.8.3</version>
</dependency>
配置文件application.yml
aliyun-oss:
#bucket名稱
bucketApp: xxx-app
domainApp: https://xxx-app.oss-cn-shenzhen.aliyuncs.com/
region: oss-cn-shenzhen
endpoint : https://oss-cn-shenzhen.aliyuncs.com
accessKeyId: 你的accessKeyId
accessKeySecret: 你的accessKeySecret
對應上面配置文件的properties類
package com.example.file.config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
@ConfigurationProperties(prefix = "aliyun-oss")
@Data
public class AliyunOSSProperties {
/**
* 服務器地點
*/
private String region;
/**
* 服務器地址
*/
private String endpoint;
/**
* OSS身份id
*/
private String accessKeyId;
/**
* 身份密鑰
*/
private String accessKeySecret;
/**
* App文件bucketName
*/
private String bucketApp;
/**
* App包文件地址前綴
*/
private String domainApp;
}
上傳文件工具類
package com.example.file.utils;

List<String> fileIds = new ArrayList<>();

} finally {

return fileIds;

/**

public void deleteFile(String fileName, String bucketName) {

}

文件類型枚舉
package com.example.file.config;
public enum FileTypeEnum {
IMG(1, "圖片"),
AUDIO(2, "音頻"),
VIDEO(3, "視頻"),
APP(4, "App包"),
OTHER(5, "其他");
private Integer code;
private String message;
FileTypeEnum(Integer code, String message) {
this.code = code;
this.message = message;
}
public Integer getCode() {
return code;
}
public String getMessage() {
return message;
}
}
調用工具類上傳文件
@Override
public List<String> uploadImg(MultipartFile[] files) {
if (files == null) {
throw new BusinessException(BusinessErrorCode.OPT_UPLOAD_FILE);
}
try {
return aliyunOSSUtil.uploadFile(files, FileTypeEnum.IMG, aliyunOSSProperties.getBucketProduct(), null, aliyunOSSProperties.getDomainProduct());
} catch (Exception e) {
logger.error("uploadImg error e:{}", e);
throw new BusinessException(BusinessErrorCode.UPLOAD_FAIL);
}
}
返回的List是文件上傳之後文件的文件名集合。
到此就整合完成了。可以登錄OSS控制檯查看對應的文件。
