上一章节【工具】OSS阿里云存储服务--超级简单--个人还是觉得Fastdfs好玩
https://www.cnblogs.com/Yangbuyi/p/13488323.html
接上一个文章讲解还有一个东西忘记说
AccessKey 这玩意用来搞认证的 差不多
开通就好了..等会要用到
步入正题创建oss模块也就是一个项目

创建Config.properties配置文件到resources下
#阿里云OSS配置
endpoint = oss-img.yangbuyi.top # 访问节点 这里表示 uri访问的图片域名相当于一个域名
bucketName = yangbuyi-img # 你创建的Bucket
picLocation = 文件夹路径 随便填 如: yangbuyi/
accessKeyId = 第一张图片要你开通的 ID
accessKeySecret = 第一张图片要你开通的 密码
创建SystemConfig.java 处理配置文件

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
/**

// 编码转换，从ISO-8859-1转向指定编码

}
创建config文件夹下的OSSConfig.java

在测试当中创建测试类

public class two {

看到这 是不是觉得 超级简单 就CV大法。。
