If you’re not familiar with Spring Boot yet, probably the year 2023 would be the best time to become familiar with it. With Spring Boot, all the pains associated with dependency management, configuration, bean declaration, etc., are taken care of. Spring makes Java development easier.

By offering features such as starter dependency, Auto-configuration, Spring Boot CLI, Spring Initializer, and Spring Boot Actuator, Spring Boot makes Java development fun and web development easy. But the best thing about Spring Boot is how it allows you to run Java applications. What do you think?

The classic primary method is now available for running Spring applications via Spring Boot, just as if you were running a core Java application. No Setting up a web server, creating a war file, and deploying it into a servlet container are all necessary. You can run Spring boot from the command prompt just as you would run any core Java application.  Various applications like Nimbuzz Messenger, ThinkFree Office (a desktop bases app), Signal (Encrypted Messaging Services), etc are built using Java. You can too create such applications if you learn Java from the best Java training institute in Kolkata.

What’s Spring Boot?

The Spring Boot framework is a Java-based framework that help to develop microservices. It provides a streamlined way to create Spring-based applications with minimal configuration and boilerplate code, allowing developers to focus on writing business logic rather than dealing with infrastructure setup.  A few features of Spring Boot are-

• The Tomcat server, Jetty server, or Undertow server can be directly embedded.
• Building configuration can be simplified by providing ‘starter’ dependencies.
• Health checks, externalized configuration, and other production-ready features are available.
• XML configuration is not required and no code generation is required.

What is the need of Spring Boot?

If you have certain questions like- What is the purpose of the project for your college academics? Do you plan to pursue this career long-term? How about starting your business by building your own website? How does Spring Boot interest you? then you must understand its benefits first. As listed below, Spring Boot offers many features and advantages that you must know-  

• XML configurations, Java Beans, and Database Transactions can be configured in a flexible way using this software.
• This application manages REST endpoints and provides batch-processing capabilities.
• Nothing needs to be configured manually with Spring Boot; everything is automatically configured.
• A spring application based on annotations is offered.
• Manages dependencies more efficiently.
• A Servlet Container is embedded in it.

Hope, you develop a clear idea that why you must learn Spring Boot. 

The Roadmap to Learning SpringBoot

Start by looking at Spring Boot’s Overview. Several blogs related to Spring Boot should be read and some Spring Boot-related research should also be done. To learn more about Spring Boot, read blogs such as Introduction to Spring Boot and Why Spring Boot? In the case that Spring is already here, etc., make complete mental preparation for your Spring Boot journey. Develop some awesome Spring Boot projects by motivating yourself to learn them. Start learning Spring Boot one concept at a time and do it regularly. Before you begin your journey with Spring Boot, it would be a good idea to attend some workshops or conferences. Decide what you want to achieve and proceed toward it.

Why Spring Boot but not Spring? Get your basics right if you want to get a better understanding of all the concepts. This step may be considered a prerequisite. Before learning Spring Boot, you should learn Java in depth.

1. Core Java

Known for its Java-based architecture, Spring Boot is a framework for building applications. Be sure you understand every Java concept starting from abstraction to threading. Understanding Java concepts makes handling projects much easier.

2. REST API

You should become familiar with RESTful web services when you are developing websites.

3. MVC architecture

Model View Controller architecture divides applications into three main logical layers.

As long as you achieve the above milestones, you have the potential of acquiring some skills with spring boot projects.

4. Design Patterns

Delegation (an object-oriented design pattern), mapping of objects, and adapter design patterns are all examples of software design patterns that play key roles in the flow and structure of a project.

5. Lombok

Java library Lombok reduces boilerplate code using reduces boilerplate code. Boilerplate code is automatically generated using annotations.

6. JUnit

There is always a preference for a test launch before a final launch, isn’t there? Our code should always be tested. This is something we should do as developers. Testing every possible scenario requires constant updating of test cases. It is possible that the same set of test cases won’t find bugs if they are repeated often enough.

7. JaCoCo

Code coverage can be checked with JaCoCo, a free coverage library. It is considered good development practice to have at least 90% coverage.

You can also practice Swagger, logger, configuration handling, data fencing, and configuration handling to keep you on target. If you followed any other practices to stay on the Spring Boot track, please feel free to add them.

Few highlights on Spring Framework

Spring MVC: The Spring Framework includes a robust Model-View-Controller (MVC) framework for building web applications. Spring MVC simplifies the development of web applications by providing a flexible architecture, powerful data binding capabilities, and support for various view technologies.

Spring Data: Spring Data provides a consistent and simplified way to access and work with different data stores, including relational databases, NoSQL databases, and more. It offers a unified programming model and reduces boilerplate code by generating repository implementations dynamically based on interfaces.

Spring Security: Spring Security is a highly customizable and feature-rich security framework for securing Java applications. It provides authentication, authorization, and protection against common security vulnerabilities. Spring Security integrates well with other Spring projects, making it easy to add security to Spring-based applications.

Transaction Management: The Spring Framework offers declarative transaction management, allowing developers to annotate methods or classes with transactional metadata. This simplifies the management of database transactions, ensuring data integrity and consistency.

Testing Support: Spring provides extensive support for testing, including integration testing and unit testing. It offers features like dependency injection for test cases, support for mocking and stubbing dependencies, and integration testing with embedded servers.

Conclusion

Remember that learning any technology or Java Spring Boot in Kolkata requires time and effort. It’s essential to consider your specific needs and the requirements of the projects you’re working on before deciding to learn Spring or any other technology. However, given its popularity, extensive features, and industry demand, learning the Spring Framework can be a valuable investment for Java developers.
