春季：春季框架是最流行的Java应用程序开发框架。 Spring框架的主要功能是依赖项注入或控制反转(IoC)。借助于Spring Framework，我们可以开发一个松散耦合的应用程序。如果纯粹定义应用程序类型或特征，则最好使用。
Spring Boot： Spring Boot是Spring Framework的模块。它允许我们构建具有最少配置或零配置的独立应用程序。如果我们要开发一个简单的基于Spring的应用程序或RESTful服务，最好使用。
下面讨论Spring和Spring Boot之间的主要比较：
| Spring | Spring Boot |
|---|---|
| Spring Framework is a widely used Java EE framework for building applications. | Spring Boot Framework is widely used to develop REST APIs. |
| It aims to simplify Java EE development that makes developers more productive. | It aims to shorten the code length and provide the easiest way to develop Web Applications. |
| The primary feature of the Spring Framework is dependency injection. | The primary feature of Spring Boot is Autoconfiguration. It automatically configures the classes based on the requirement. |
| It helps to make things simpler by allowing us to develop loosely coupled applications. | It helps to create a stand-alone application with less configuration. |
| The developer writes a lot of code (boilerplate code) to do the minimal task. | It reduces boilerplate code. |
| To test the Spring project, we need to set up the sever explicitly. | Spring Boot offers embedded server such as Jetty and Tomcat, etc. |
| It does not provide support for an in-memory database. | It offers several plugins for working with an embedded and in-memory database such as H2. |
| Developers manually define dependencies for the Spring project in pom.xml. | Spring Boot comes with the concept of starter in pom.xml file that internally takes care of downloading the dependencies JARs based on Spring Boot Requirement. |
Spring Boot： Spring Boot使快速引导和开始开发基于Spring的应用程序变得容易。它避免了很多样板代码。它在幕后隐藏了很多复杂性，因此开发人员可以快速上手并轻松开发基于Spring的应用程序。
Spring MVC： Spring MVC是用于构建Web应用程序的Web MVC框架。它包含许多用于各种功能的配置文件。这是一个面向HTTP的Web应用程序开发框架。
Spring Boot和Spring MVC的存在目的不同。下面讨论了Spring Boot和Spring MVC之间的主要比较：
| Spring Boot | Spring MVC |
|---|---|
| Spring Boot is a module of Spring for packaging the Spring-based application with sensible defaults. | Spring MVC is a model view controller-based web framework under the Spring framework. |
| It provides default configurations to build Spring-powered framework. | It provides ready to use features for building a web application. |
| There is no need to build configuration manually. | It requires build configuration manually. |
| There is no requirement for a deployment descriptor. | A Deployment descriptor is required. |
| It avoids boilerplate code and wraps dependencies together in a single unit. | It specifies each dependency separately. |
| It reduces development time and increases productivity. | It takes more time to achieve the same. |
