How many Layers are in Spring Boot?

 Spring Boot framework offers a collection of preset features and standards that enable programmers to create apps fast and with little setup. Spring Boot builds on the well-known Spring Framework and adds a variety of capabilities. These include auto-configuration, embedded servers, and a command-line interface, to streamline the process of developing applications.

One of Spring Boot's main advantages is that it makes it easier to set up and configure Spring-based applications, freeing developers to concentrate more on designing business logic and less on configuration. Spring Boot is a popular choice for developing web apps, RESTful APIs, and microservices since it offers a broad variety of plugins and extensions for interacting with other well-known technologies.

Significant Features of Spring Boot

Building contemporary, scalable, and robust applications is made easier with the help of Spring Boot, which offers a number of features and advantages. It is a well-liked option for creating contemporary, scalable, and robust applications since it offers a broad collection of capabilities that make application development and deployment easier.

·         Auto-configuration- In order to automatically set up the application based on the classpath and environment, Spring Boot employs a convention-over-configuration strategy.

·         Embedded servers- It is not necessary for developers to deploy the application to an external server because Spring Boot contains support for embedded servers like Tomcat, Jetty, and Undertow.

·         Actuator- Metrics, health checks, and tracing are just a few of the endpoints that Spring Boot Actuator offers for controlling and monitoring the application.

·         Spring Data- Support for Spring Data is included in Spring Boot, which makes interacting with various data sources simple by offering a common API.

·         Spring Security- Support for Spring Data is included in Spring Boot. This makes interacting with various data sources simple by offering a common API.

·         Externalized configuration- This tool helps developers externalize configuration properties. It makes it easy to configure the application for different environments and deployments.

·         Developer tools- A variety of developer features in Spring Boot, such LiveReload and hot-swapping, may increase developer productivity and cut down on development time.

How many layers are in Spring Boot?

Although layered architecture is not strictly enforced by Spring Boot, it is frequently used in conjunction with an architecture that divides the program into many logical levels. The precise number and composition of layers may change based on the complexity and requirements of the application, and these layers can be implemented in a variety of methods. Nevertheless, structuring Spring Boot applications using a layered architecture is popular and efficient. Many institutes provide Spring Boot Online Training and one can enroll in them to start a career in it. The following layers could be present in a typical layered architecture for a Spring Boot application:

·         The presentation layer (web layer) manages the user input and output activities in relation to the user interface. It generally consists of Spring MVC controllers, which take requests and provide answers in JSON, HTML, or XML.

·         The service layer orchestrates interactions between the display layer and the data access layer and offers business logic. It often contains services controlled by Spring that carry out activities particular to an application.

·         Access to data sources like databases or RESTful APIs is made possible via the data access layer (persistence layer). It often comprises Spring Data repositories that give a uniform interface for data access while abstracting away the actual data source.

·         The domain layer (also known as the model layer) is where the objects or entities that reflect the concepts and laws of business are found. It frequently consists of entities controlled by Spring that correspond to database tables or other data sources.

Conclusion

Popular open-source Java framework Spring Boot offers a number of features and advantages for creating contemporary, scalable, and resilient applications. By offering auto-configuration, embedded servers, externalized configuration, developer tools, and interaction with other well-known technologies like Spring Data and Spring Security, it streamlines the development process. Although a layered architecture is not necessarily required by Spring Boot, it is frequently used in combination with one that divides the application into many logical levels, such as the presentation, service, data access, and domain layers. This strategy can increase the application's scalability, testability, and maintainability.
