【阿里OSS】java后台集成OSS的SDK之版本升级及工具封装
环境：
maven 3.0
jdk 1.8
原oss版本2.8.3
升级后为：3.5.0
pom依赖：
com.aliyun.oss aliyun-sdk-oss 3.5.0
配置文件添加：
# ======= 阿里OSS配置 ========= aliyun.OSS.endpoint=http://oss-cn-beijing.aliyuncs.com aliyun.OSS.accessKeyId= 自个的KEY aliyun.OSS.accessKeySecret= 同上 aliyun.OSS.bucketName=afinal2mc #自己定义的存储空间 aliyun.OSS.filedir=sys/ #自己在存储空间创建的文件夹 aliyun.OSS.fileMaxSize=10 #文件上传最大M数

注意：2.0+使用的是OSSClient对象，而3.0+使用的是OSS对象。
创建方式也不一样，一个是newOSSClient一个是通过Builder对象获取
