Springboot集成阿里云OSS对象存储功能

首先登录阿里云账号

到控制台里选择对象存储OSS,开通oss,注意此服务会根据流量收取费用

点击Access Key按要求创建进行,

记下AccessKey  和Accesssecret

在项目里添加阿里云的依赖


   com.aliyun.oss
   aliyun-sdk-oss
   2.4.0


   commons-fileupload
   commons-fileupload
   1.3.1

application.yml详细的配置文件

oos:
   endpoint: oss-cn-shanghai.aliyuncs.com
   keyid:    xxxxxxxx # 填写刚刚生成的AccessKey
   keysecret: xxxxxxx  # 填写刚刚生成的Accesssecret
   bucketname: 2019131 # bucket名称
   filehost: 11111    #bucket下文件夹的路径

endpoint是根据你新建申请bucket地域选择的,点击+号

新建完bucket点击你的bucket、

外网访问里找到endpoint

 

下面是详细代码

获取application.yml配置的ConstantProperties类

import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Data
@Component
@ConfigurationProperties(prefix = "oos")
public class ConstantProperties {
    private  String endpoint;
    private  String keyid;
    private  String keysecret;
    private  String bucketname;
    private  String filehost;
}

上传,获取文件列表,删除的util类
