Spring Boot is an extension of the Spring Framework, and is designed to simplify the process of building and deploying Spring-based applications. Spring Boot builds upon the core functionality of the Spring Framework, while also providing a number of additional features and capabilities.
Here are some of the key ways in which Spring Boot relates to the Spring Framework:
Core Functionality: Spring Boot builds upon the core functionality of the Spring Framework. This means that it uses the same basic principles and concepts as the Spring Framework, such as dependency injection, aspect-oriented programming, and containerization. However, Spring Boot provides a simpler and more streamlined approach to these concepts, which makes it easier to get started with Spring.
Configuration: One of the main differences between Spring Boot and the Spring Framework is in how they handle configuration. While the Spring Framework requires developers to write a lot of configuration code, Spring Boot provides a more opinionated and automated approach. It uses sensible defaults and auto-configuration to minimize the amount of configuration code that developers need to write. This means that developers can get up and running with Spring Boot more quickly, without having to spend as much time on configuration.
External Libraries: Spring Boot includes a number of external libraries that are commonly used in Spring-based applications. For example, it includes libraries for connecting to databases, handling web requests, and processing JSON data. This makes it easier for developers to build Spring-based applications, since they don’t need to manually configure and integrate these libraries themselves.
Embedded Servers: Spring Boot includes embedded servers like Tomcat, Jetty, and Undertow, which means that developers don’t need to set up a separate server environment in order to run their application. This makes it easier to get started with Spring Boot, since developers can simply run their application as a standalone JAR file.
Microservices: Spring Boot is particularly well-suited for building microservices-based applications. It provides features like embedded servers, health checks, and monitoring that are useful for building lightweight, scalable, and modular applications.
Overall, Spring Boot is a powerful and flexible extension of the Spring Framework. While it builds upon the core functionality of the Spring Framework, it provides a more opinionated and automated approach that simplifies the process of building and deploying Spring-based applications.
