Spring Boot Tutorial – Trends24US

Spring Boot is a popular Java-based framework used for building web applications and microservices. It is built on top of the Spring Framework and provides a simple way to set up and configure a new project. Spring Boot automatically configures and sets up all the necessary components, making it easy for developers to get started quickly.

Here is a simple tutorial on how to create a Spring Boot project:

1. Install the latest version of the Java Development Kit (JDK) and the Spring Boot CLI.
2. Create a new project by using the Spring Boot CLI’s “spring init” command. For example, to create a new project called “my-project”, you would enter the following command:

3. Navigate to the project’s root directory and open the pom.xml file. This file contains the project’s dependencies, build information, and other configurations. You can add or remove dependencies as needed.
4. Create a new package in the src/main/java directory, and create a new class within that package. This class will be the main class of your application, and it should be annotated with the @SpringBootApplication annotation.
5. In the main class, add a “main” method and call the SpringApplication.run() method, passing in the class as an argument. This will start the application.
6. To run the application, use the “./mvnw spring-boot:run” command in the project’s root directory.
7. To test the application, you can use a web browser and navigate to “http://localhost:8080“.

This is a basic tutorial on how to create a Spring Boot project. There are many other features and configurations that can be added to a Spring Boot project, such as security, data access, and more. The Spring Boot documentation is a great resource for learning more about the framework and how to use it.
