背景：selenium是python爬虫，同时也是自动化测试使用的一个模块，当然不止有python语言版，本文就是Java版，因为python相关的博客很多了，而我个人更加倾向使用Java到实际的工作项目中。在几年前，尤其是没有做过web相关开发之前，曾经使用过不少python进行过爬虫练习，但都是零零星星地跟着其它博客的例子进行学习，改造成为自己的需求。不过，在经历了webgis开发，部分Java开发甚至安卓移动端自动化（用的是Auto.js，后面的文章有时间会写相关的内容）后，便有了想往PC端浏览器学习扩展的想法，于是就有了这篇文章。
这个例子是以12306网站进行练习记录一些常见的PC浏览器的HTML domcument文档元素的查找方法和操作动作（模拟交互）如：查找element（根据id，根据class，根据标签名，根据css选择器，根据xpath等等）的相关信息或对象，模拟鼠标，键盘动作，浏览器对象操作方法。在这不对每一个方法单独拆分写，顺序稍微乱些。
