Spring Boot is a Java framework that makes it easier to create and run Java applications. It simplifies the configuration and setup process, allowing developers to focus more on writing code for their applications.

This Spring Boot Tutorial is a comprehensive guide that covers both basic and advanced concepts of the Spring Framework. It is designed for beginners as well as professionals.

Spring Boot Tutorial


Spring Boot, a module of the Spring framework, facilitates Rapid Application Development (RAD) capabilities.

This Spring tutorial includes basic to advanced topics of Spring Boot, like Basics of Spring Boot, Spring Boot core, Spring Boot REST API, Spring Boot with Microservices, Spring Boot with Kafka, Spring Boot with Database and Data JPA, etc.

What is Spring Boot?

Spring Boot is an open-source Java framework used to create a Micro Service. Spring boot is developed by Pivotal Team, and it provides a faster way to set up and an easier, configure, and run both simple and web-based applications. It is a combination of Spring Framework and Embedded Servers. The main goal of Spring Boot is to reduce development, unit test, and integration test time and in Spring Boot, there is no requirement for XML configuration.

Prerequisite of Spring Boot

  • Understanding of Java syntax and core concepts such as classes, objects, inheritance, interfaces, and exception handling
  • Basic understanding of the Spring framework
  • Knowledge of Web Technologies
  • Familiarity with build tools such as Maven or Gradle

What You Can Do with Spring Boot

Spring Boot allows for the rapid development of apps. It examines your classpath and the beans you’ve configured, makes educated guesses about what you’re missing, and adds those objects. With Spring Boot, you can concentrate on business aspects rather than infrastructure.

Spring Boot Features

  • Web Development
  • Spring Application
  • Application events and listeners
  • Admin features
  • Externalized Configuration
  • Properties Files
  • YAML Support
  • Type-safe Configuration
  • Logging
  • Security

Spring Boot Advantages

  • It generates standalone Spring applications that are launched with the Java -jar command.
  • It easily tests web applications using several Embedded HTTP servers like as Tomcat, Jetty, and others. We don’t need to distribute WAR files.
  • It provides ‘starter’ POMs with strong opinions to help us simplify our Maven settings.
  • It includes features that are ready for production, such as metrics, health checks, and externalised settings.
  • There is no need for XML configuration.
  • It includes a command-line utility for designing and testing Spring Boot applications.
  • It provides a number of plug-ins.
  • It also minimizes writing multiple boilerplate codes, XML configuration, and annotations.
  • It boosts productivity while decreasing development time.

Limitations of Spring Boot

While Spring Boot is powerful, it has some drawbacks to consider:

  • It can be tricky to learn at first, especially for beginners.
  • It may use more memory and take longer to start compared to simpler frameworks.
  • Its conventions can restrict customization options for specific needs.
  • Managing multiple microservices can get complicated.
  • Upgrading or integrating with certain tools may be tricky.
  • Applications built with Spring Boot can be larger to deploy.


You’ve made it through our Spring Boot tutorial, and now you have a solid grasp of essential concepts like dependency injection, Spring Boot starters, and application configuration. With these new skills, you’re ready to build and deploy efficient, scalable Java applications. Spring Boot simplifies the development process, whether you’re creating microservices, RESTful web services, or enterprise applications. Keep exploring the vast Spring Boot ecosystem, stay active in the developer community, and apply what you’ve learned to real-world projects.
