Spring代替了springboot的哪些功能？

Answer 1

Spring是Spring Boot的基础，利用了spring的诸多特性，例如注解/Java config/条件配置等等。不过由于有嵌入的web容器，预计未来很多会只提供RPC，HTTP服务的——以前用SpringMVC的项目，会用Spring Boot应用来替代。

Answer 2

Spring Boot is the starting point for building all Spring-based applications. Spring Boot is designed to get you up and running as quickly as possible, with minimal upfront configuration of Spring.

官方有解释的，spring并没有替换springboot。spring是基础。
