Revealing the architecture of Spring Boot: in-depth analysis of the secrets behind the framework

php editor Baicao will take you to reveal the architecture of Spring Boot and deeply analyze the secrets behind the framework. As a popular Java development framework, Spring Boot’s design concept and internal mechanism contain many contents worth discussing. Through an in-depth analysis of Spring Boot's architecture, we can better understand its operating principles and advantages, providing developers with a more efficient and convenient development experience. Follow the editor to explore the mysteries of Spring Boot and unlock more development skills and practical knowledge!

• Spring core module: spring Boot’s core module provides the basic functions of the Spring framework, including dependency injection, aop, TransactionManagement, etc. These modules are the foundation of Spring applications and provide a solid foundation for Spring Boot's development.
• Spring Boot Starter: Spring Boot Starter is a pre-configured dependency collection that helps developers quickly build Spring applications. Spring Boot Starter provides a variety of dependencies, covering a variety of commonly used functions, such as web development, data access, security, etc. By using Spring Boot Starter, developers can easily integrate the required functionality into Spring applications.
• Spring Boot Actuator: Spring Boot Actuator is a module that provides application runtime information. It provides a number of endpoints that allow developers to monitor the status, metrics and logs of their applications. By using Spring Boot Actuator, developers can easily understand the running status of the application and find and fix problems in time.
• Spring Boot Autoconfiguration: Spring Boot Autoconfiguration is an automatic configuration module that can automatically detect components in the application and configure them accordingly. Spring Boot Autoconfiguration can greatly simplify the configuration of Spring applications. It can automatically detect and configure Spring Beans, data sources, Message Queue and other components.
• Spring Boot CLI: Spring Boot CLI is a command line tool that helps developers quickly create, run and test Spring Boot applications. Spring Boot CLI provides many commands to help developers complete various common tasks, such as creating new projects, starting applications, testing applications, etc.

Spring Boot’s architecture is a highly modular and extensible architecture that allows developers to customize Spring applications as needed. Spring Boot provides many out-of-the-box features to help developers quickly build and deploy Spring applications.

The following is a code example demonstrating the Spring Boot architecture:

@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}

In this example, the @SpringBootApplication annotation is a combined annotation, which includes @Configuration, @EnableAutoConfiguration and @ComponentScanThree comments. The @Configuration annotation indicates that this is a Spring configuration class, the @EnableAutoConfiguration annotation enables the automatic configuration function of Spring Boot, and the @ComponentScan annotation scans components under the specified package.

By running this example, we can create a simple Spring Boot application. This application will automatically configure a WEBserver and provide a simple homepage.

Spring Boot is a powerful framework that simplifies the development of Spring applications. By understanding Spring Boot's architecture, developers can better use Spring Boot and build high-quality Spring applications.
