Spring boot Architecture
Spring Boot is built on top of the Spring Framework and follows a layered architecture that promotes modularity, loose coupling, and easy extensibility. The architecture of a Spring Boot application typically consists of the following key components:
The presentation layer handles the user interface and interaction with the application. It is responsible for handling incoming requests, processing them, and generating responses. In a Spring Boot application, the presentation layer is usually implemented using Spring MVC, which provides powerful support for building RESTful APIs and web applications.
The application layer contains the business logic of the application. It processes the data received from the presentation layer, performs required operations, and interacts with the data layer for data access. This layer is responsible for implementing the core functionality of the application.
The data layer deals with data storage and retrieval. It is responsible for interacting with databases, external services, or any data source. In Spring Boot applications, the data layer is often implemented using Spring Data, which simplifies data access by providing a consistent and easy-to-use API for various data sources.
Spring Boot emphasizes convention over configuration, making it easy to set up and configure the application. Configuration in a Spring Boot application is typically done using properties files (e.g.,
application.yml) or through environment variables. The configuration allows you to enable or disable various features, specify properties, and customize behavior.
Spring Boots auto-configuration is a powerful feature that automatically configures beans based on the classpath and dependencies present in the project. It eliminates much of the boilerplate configuration, making it easier to set up the application. Auto-configuration works by detecting the presence of certain classes or jars on the classpath and configuring beans accordingly.
Spring Boot introduces the concept of "starters," which are sets of pre-configured dependencies for specific use cases. Starters simplify dependency management and reduce the need for explicit version declarations. You can include starters in your project to add specific functionality without manually managing individual dependencies.
Spring Boot comes with embedded servers like Tomcat, Jetty, or Undertow. This allows you to package your application as a stand-alone JAR with an embedded server, making deployment and execution straightforward.
Spring Boot Actuator is a module that provides production-ready features for monitoring and managing the application. It automatically exposes endpoints for health checks, metrics, tracing, and more, allowing you to monitor the applications status and performance in production.
Overall, Spring Boots architecture promotes rapid development, modular design, and efficient application setup. It simplifies many aspects of building Java applications and allows developers to focus on writing business logic rather than spending time on boilerplate code and configuration.
