Compare Spring Boot and Spring MVC and understand their differences

With the continuous development of Java development, the Spring framework has become the first choice for many developers and enterprises. In the Spring ecosystem, Spring Boot and Spring MVC are two very important components. Although they are both based on the Spring framework, there are some differences in functions and usage. This article will focus on comparing the differences between Spring Boot and Spring MVC to help readers better understand them.

First, let us understand Spring Boot. Spring Boot is a framework for simplifying Spring application development. Compared to traditional Spring applications, Spring Boot provides a simpler and faster way to build stand-alone, executable, production-level applications. Its main goal is to reduce the tedious work of developers when deploying and configuring applications, allowing them to focus more on the development of business logic. The Spring Boot configuration file is concise and clear, supports automatic configuration, and can automatically configure various components and functions according to the needs of the application. Additionally, Spring Boot provides an additional set of tools and plugins for developing and testing Spring applications.

Spring MVC is a Web framework in the Spring framework, used to develop Web applications based on the MVC pattern. It is based on Servlet technology and provides a flexible and customizable way to build web applications. Spring MVC maps the request to the controller, handles the request by the controller, and then returns the appropriate view response to the client. It provides features such as request mapping, data binding, validation, error handling, etc., making it easier for developers to develop and manage web applications.

So what are the main differences between Spring Boot and Spring MVC? First of all, Spring Boot is a framework used to simplify Spring application development, and Spring MVC is a web framework within the Spring framework. In short, Spring Boot provides a higher level of abstraction and automatic configuration, allowing developers to build and deploy Spring applications more quickly and conveniently, while Spring MVC is more focused on the development and management of web applications.

Secondly, Spring Boot's goal is to reduce the developer's workload when configuring and deploying applications. It provides automatic configuration and default values ​​as well as a series of out-of-the-box features to enable applications to Get up and running quickly. Spring MVC focuses more on providing a flexible and customizable way to build web applications. Developers can choose appropriate configurations and components to customize their applications according to their own needs.

In addition, Spring Boot has a built-in embedded Servlet container (such as Tomcat or Jetty), which can package the application into an executable JAR file, simplifying the deployment and running of the application. Spring MVC needs to rely on an external Servlet container to deploy applications, and the application needs to be packaged as a WAR file for deployment. This is one of the reasons why Spring Boot is more suitable for developing microservices and cloud-native applications than Spring MVC.

In addition, Spring Boot supports the integration of multiple data access technologies (such as JPA, Hibernate, MyBatis, etc.) and persistence layer frameworks, allowing developers to interact with the database more conveniently. As a Web framework, Spring MVC does not provide direct integration support. Developers need to choose and configure the appropriate data access technology and persistence layer framework.

In summary, although Spring Boot and Spring MVC are both components based on the Spring framework, they are different in functionality and usage. Spring Boot focuses more on simplifying and quickly developing Spring applications, providing automatic configuration and a series of out-of-the-box features. Spring MVC focuses more on the development and management of Web applications, providing a flexible and customizable way to build Web applications. Developers can choose the appropriate framework to develop and manage their applications based on their needs. No matter which framework you choose, it is important for developers to understand their differences and features.
