Spring Boot
对构建可用于生产的Spring应用程序持坚定态度。
Spring Boot 倾向于使用约定而非配置，它旨在使您尽快启动并运行。
是什么
Spring Boot简化了基于Spring的应用开发，通过少量的代码就能创建一个独立的、产品级别的Spring应用。
Spring Boot为Spring平台及第三方库提供开箱即用的设置，这样你就可以有条不紊地开始。
多数Spring Boot应用只需要很少的Spring配置。
Spring Boot是由Pivotal团队提供的全新框架，其设计目的是用来简化新Spring应用的初始搭建以及开发过程。
该框架使用了特定的方式来进行配置，从而使开发人员不再需要定义样板化的配置。用我的话来理解，就是Spring Boot其实不是什么新的框架，它默认配置了很多框架的使用方式，就像maven整合了所有的jar包，Spring Boot整合了所有的框架（不知道这样比喻是否合适）。
Spring Boot的核心思想就是约定大于配置，一切自动完成。
采用 Spring Boot 可以大大的简化你的开发模式，所有你想集成的常用框架，它都有对应的组件支持。
ps: 感觉这点和 maven 是比较类似的。
