internship：继之前的代码优化及其部分涉及内容的了解

swagger（ API 框架）的涉及：
在代码中使用自定义的注解来生成接口文档，这个在前后端分离的项目中很重要。这样做的好处是 在开发接口时可以通过swagger 将接口文档定义好，同时也方便以后的维护

由此我也真正接触到后端的真正工作，提供接口，也由此明白下发的word文档的意义——没有swagger之前，我们可以使用word，excel等功能来书写接口定义文档。实际项目中非常需要写文档，提高Java服务端和Web前端以及移动端的对接效率。

继上一次代码 进行的优化 比如添加方法上的注解 及其判定数据类型赋值为null 或者为0等等。
