简单来说，它可以表述为:

Spring boot = Spring MVC +自动配置(不需要编写Spring .xml文件进行配置)+服务器(您可以有嵌入式Tomcat, Netty, Jetty服务器)。

Spring Boot是一个opiniated框架，因此它的构建考虑到了开发速度快，配置时间短，并且有很好的社区支持。

Spring MVC is a complete HTTP oriented MVC framework managed by the Spring Framework and based in Servlets. It would be equivalent to JSF in the JavaEE stack. The most popular elements in it are classes annotated with @Controller, where you implement methods you can access using different HTTP requests. It has an equivalent @RestController to implement REST-based APIs. Spring boot is a utility for setting up applications quickly, offering an out of the box configuration in order to build Spring-powered applications. As you may know, Spring integrates a wide range of different modules under its umbrella, as spring-core, spring-data, spring-web (which includes Spring MVC, by the way) and so on. With this tool you can tell Spring how many of them to use and you'll get a fast setup for them (you are allowed to change it by yourself later on).

因此，Spring MVC是一个用于web应用程序的框架，Spring Boot是一个基于Spring的生产就绪项目初始化器。您可能会发现访问Spring MVC标记wiki以及SO中的Spring Boot标记wiki很有用。

SpringBoot实际上是预配置的，减少了锅炉配置，并提供了最简单或快速的方式来启动应用程序。

SpringBoot将令人头痛的配置问题从开发人员转移到它自己，而不是Spring。

隐式SpringBoot基于Spring框架概念，如bean、控制器、服务、jpa等。

可以说SpringBoot是Spring的包装器。

在SpringBoot中，服务器的默认端口是8080，但如果你想改变，那就去你的应用程序。属性和写入

server.port = 8084

这样想:

Spring MVC是一个基于web实现MVC架构的框架。

Spring Boot是一个面向程序员的工具。程序员必须专注于编程，工具必须专注于配置。所以我们不需要浪费时间配置一堆xml来创建一个简单的“Hello world”。

Without repeating the same thing in previous answers, I'm writing this answer for the people who are looking to starting a new project and don't know which is the best framework to startup your project. If you are a beginner to this framework the best thing I prefer is Use spring boot(with STS /Spring Tool Suite). Because it helps a lot. Its do all configurations on its own. Additionally, use Hibernate with spring-boot as a database framework. With this combination, your application will be the best. I can guarantee that with my experiences.

即使这是JEE(目前)最好的框架之一，但在不久的将来它也会消亡。有一些轻量级的替代品即将问世。所以要不断更新你的经验，不要拘泥于一个特定的框架。最好的事情是精通概念，而不是框架。
