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

以下是区分Spring、Spring MVC和Spring Boot的一些要点:

春天:

Main Difference is "Test-ability". Spring come with the DI and IOC. Through which all hard-work done by system we don't need to do any kind of work(like, normally we define object of class manually but through Di we just annotate with @Service or @Component - matching class manage those). Through @Autowired annotation we easily mock() it at unit testing time. Duplication and Plumbing code. In JDBC we writing same code multiple time to perform any kind of database operation Spring solve that issue through Hibernate and ORM. Good Integration with other frameworks. Like Hibernate, ORM, Junit & Mockito.

Spring MVC

Spring MVC框架是Spring的一个模块，它为面向HTTP的web应用开发提供了便利。 Spring MVC在输入逻辑(控制器)、业务逻辑(模型)和UI逻辑(视图)上有明确的代码分离。 Spring MVC模式有助于开发灵活和松散耦合的web应用程序。 根据您的需要，提供各种硬编码方式来定制您的应用程序。

Spring Boot:

Create of Quick Application so that, instead of manage single big web application we divide them individually into different Microservices which have their own scope & capability. Auto Configuration using Web Jar : In normal Spring there is lot of configuration like DispatcherServlet, Component Scan, View Resolver, Web Jar, XMLs. (For example if I would like to configure datasource, Entity Manager Transaction Manager Factory). Configure automatically when it's not available using class-path. Comes with Default Spring Starters, which come with some default Spring configuration dependency (like Spring Core, Web-MVC, Jackson, Tomcat, Validation, Data Binding, Logging). Don't worry about versioning issue as well.

(演化类似:Spring -> Spring MVC -> Spring Boot，所以新版本兼容旧版功能。) 注:它不包含所有点。

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。

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”。

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

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。
