lombok使用

lombok了解

官方解释：
Project Lombok is a java library that automatically plugs into your editor and build tools, spicing up your java.
Never write another getter or equals method again, with one annotation your class has a fully featured builder, Automate your logging variables, and much more.
理解：
是一个构建工具，java库，自动化插件，可以通过添加注解实现再也不需要写getter和equals方法了
