首先抱歉我忘记了最初版本是摘自哪位大牛的了,实在不好意思,感谢他/她;

粗糙测试:postman同时(相差2秒内)send请求访问阿里云OSS的普通上传和分片上传212MB的eclipse-jee-indigo-SR2-64.zip;

得到21:7:13========21:9:7(分片)--->耗时2分钟

得到21:7:11================21:15:23(普通上传)--->耗时8分钟


至于拿配置文件里面的值的方法.恕我不能展示出来,那些是公司的代码, 其实也很简单,但是使用的是公司内部封装的,其实底层也就是jdk的api, 并且这种方式是比较老的,不是框架直接注解@就导入. 大家用自己习惯的方式注入值就好了.(建议不要把值直接写在类里)

整个类import比较简单 只有aliyunOss必须的一个sdk:《aliyun-sdk-oss-2.3.0.jar》


注意:

①由于是测试, 所以这个工具类我给它加了@Controller注解和对应的接口url,实际运用时, emmmm,你们自己看着办吧。当工具类调用也可以,直接当上传视频的接口也可以。 

②由于是测试, 我返回return的是时间差, 你们要用来上传到阿里云OSS储存桶的时候把 被注释掉的那行return解封,把下面的时间代码删除即可。
