Spring Boot Tutorial for Beginners: Learn Spring Boot in 10 Steps

Spring Boot is widely used in the Java development community for building a wide range of applications, from traditional monolithic systems to modern microservices architectures. Its ability to simplify and accelerate the development process, along with its robust features, makes it a popular choice for Java developers. The Spring Framework’s basic and advanced ideas are covered in depth in the spring boot tutorial for beginners. However, the below guide is designed for both experts and beginners. 

Spring Boot Characteristics and Features

The below key features make spring boot for beginners easy to learn and use:

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

Spring Boot Framework

It is an open-source Java framework useful for creating Microservices. Spring Boot, developed by Pivotal Team, provides a quicker and easier way to install web-based applications. It also helps to configure and run both basic and web-based applications.

Those who learn Spring Boot from scratch are already aware of these advantages. Moreover, with Spring Boot, there is no need for XML configuration. Additionally, it also cut down on development, unit, and integration test times.

Below are the key components of the Spring boot:

• Spring Boot starters
• Elegant configuration management
• Spring Boot Actuator
• Spring Boot autoconfiguration
• Easy-to-use embedded servlet container support

Spring Boot Tutorial for Beginners Step-By-Step

You can then explore each step in more detail by referring below writeup. Cover all these topics to learn spring boot from scratch:

1. Basics

• The basic cover main topics:
• Introduction to Spring Boot
• Benefits of choosing Spring Boot For Microservices Development
• A Complete Roadmap to Master Spring Boot is also crucial
• Difference between Spring and Spring Boot
• Difference between Spring MVC and Spring Boot
• Steps to Create a Simple Spring Boot Project
• Method to Run Spring Boot Application

2. Learn Java Programming

This next step in a spring tutorial for beginners is to learn Java programming language in depth. Therefore, go through the essential Java concepts.

3. Spring Framework

In this section of the Spring boot tutorial for beginners, you learn some of the essential Spring Framework concepts. Hence, below are what you need to learn about the spring framework. 

• Core: Bean Life Cycle, Dependency Injection, Inversion of Control, and Bean-Factory and Application context.
• Web: Annotations, MVC Structure, Configuration, Integrating different libraries/frameworks (Like Hibernate) and profiles
• AOP (Aspect Oriented Programming): How AOP works, creating PointCut, JoinPoint, aspect, etc.

4. Spring Security

It is the crucial step in the spring boot tutorial for beginners step by step. Moreover, the basic benefit of Spring Security, like with all other Spring projects, lies in how quickly and readily it can be customized. Therefore, it easily fits particular needs. The following ideas are crucial for Spring Security.

• Authorization
• Authentication
• OAuth2
• Form Authentications
• JWT(JSON Web Token)

5. Spring Boot

When you are ready to transition to spring boot, you should have a solid grasp of spring fireworks. Moreover, you must also know how to use spring security. Hence, everything you have done and all of the configuration you are doing for the spring application is also automated by Spring Boot. 

6. Spring Boot Actuator

• For many applications, being able to access the details of an application that is in use in production is also essential. Thus, the Spring Boot actuator offers a wide range of production-ready functionality. Moreover, it doesn’t need developers to create a lot of code. A few features of the Spring actuator include:
• It can also examine application bean configuration information
• Capable of viewing the application’s URL mappings and environment information. Additionally, it can also view configuration parameter values.
• It is also possible to view the registered health check metrics

7. REST API

The best way to learn Spring Boot is to develop the REST APIs. Furthermore, they are used in the microservices or consumed by other applications. The REST API teaches you the following things:

1. HTTP Methods: POST, GET, PUT, DELETE, OPTIONS and TRACE
2. HTTP Status Codes: 1.X.X, 2.X.X, 3.X.X, 4.X.X and 5.X.X. 

8. Databases 

Because your backend is crucial to building your application, the database portion of Spring Boot is now introduced. Thus, you must have become familiar with several database types. 

1. SQL: MySQL, PostgreSQL and Oracle
2. NoSQL: MongoDB, Cassandra, and Spring Data

9. Microservices 

They are small, loosely connected distributed services. Moreover, the scalability and innovation issues of monolith structures led to the development of microservice architectures. Thus, it enables the splitting of a huge application into smaller, more manageable components. Additionally, they have looser responsibility definitions.

10. Create Your Spring Boot Project

Spring Boot also offers a web utility called Spring Initializer for rapid application bootstrapping. So, simply generate a new Spring Boot project by going to https://start.spring.io/. Furthermore, you can go through a spring boot example as well.

The Benefits of Learning Spring Boot

• When launched using the Java -jar command, it generates independent Spring applications.
• With the help of various Embedded HTTP servers, like Tomcat, Jetty, and others, web applications can be tested with ease. However, WAR files are not necessary.
• It reduces the need to write several boilerplate programs, XML configurations, and annotations. Thus, one can easily start learning it with the help of a spring boot tutorial for beginners.
• As development time is cut back, productivity is increased.
• It offers starter POMs that have strong opinions. They assist you in streamlining our Maven settings.
• There are also features like metrics, health checks, and externalized settings. Such features are ready for production.
• XML setup is not required. 
• It also comes with a command-line tool. Therefore, it is easy to create and test Spring Boot applications.
• Additionally, multiple plug-ins are available.

Conclusion 

Spring Boot is one of the most well-known and widely used Java frameworks. It is a microservices-based framework that can be used quickly to create applications that are ready for production. 

The ideal Spring Boot Developer can use logical thinking and have strong problem-solving skills. Additionally, they are well-versed in Core Spring, Java, and the Spring Boot framework. So, if you are looking for a spring boot tutorial for beginners, the above blog is for you.
