SpringBoot整合阿里云OSS对象存储服务的实现
今天来整合一下SpringBoot和阿里云OSS对象存储服务。
一、配置OSS服务
先在阿里云开通对象存储服务,拿到AccessKeyId、AccessKeySecret。
创建你的bucket(存储空间),相当于一个一个的文件夹目录。按业务需求分类存储你的文件,图片,音频,app包等等。创建bucket是要选择该bucket的权限,私有,公共读,公共读写,按需求选择。创建bucket时对应的endpoint要记住,上传文件需要用到。
可以配置bucket的生命周期,比如说某些文件有过期时间的,可以配置一下。
二、代码实现
引入依赖包
配置文件application.yml
aliyun-oss:
#bucket名称
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
对应上面配置文件的properties类
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 {
/**
* 服务器地点
*/
private String region;
/**
* 服务器地址
*/
private String endpoint;
/**
* OSS身份id
*/
private String accessKeyId;
/**
* 身份密钥
*/
private String accessKeySecret;
/**
* App文件bucketName
*/
private String bucketApp;
/**
* App包文件地址前缀
*/
private String domaWOjsvSOKIinApp;
}
上传文件工具类

public List
//创建OSSClient实例
OSSClient ossClient = new OSSClient(aliyunOSSProperties.getEndpoint(), aliyunOSSProperties.getAccessKeyId(), aliyunOSSProperties.getAccessKeySecret());
List
try {
for (MultipartFile file : files) {
//创建一个唯一的文件名,类似于id,就是保存在OSS服务器上文件的文件名(自定义文件名)
String fileName = http://FileIdUtils.creater(fileTypeEnum.getCode());

logger.info("Aliyun OSS AliyunOSSUtil.uploadFileToAliyunOSS,result:{}", result);
fileIds.add(prefix + fileName);
}
} catch (IOException e) {

ossClient.deleteObject(bucketName, fileName);
shutdown(ossClient);
}
/**
* 根据图片全路径删除就图片
*
* @param imgUrl 图片全路径
* @param bucketName 存储路径
*/
public void delImg(String imgUrl, String bucketName) {

try {

} catch (OSSException oe) {

shutdown(ossClient);
}
}
/**
* 关闭oos
*
* @param ossClient ossClient

private void shutdown(OSSClient ossClient) {
ossClient.shutdown();
}
}
文件类型枚举
package com.example.file.config;
public enum FileTypeEnum {
IMG(1, "图片"),
AUDIO(2, "音频"),
VIDEO(3, "视频"),
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;
}
}
调用工具类上传文件
@Override
public List
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);
}
}
