here we will discuss Step-by-step guide to installing Java Spring Boot on Linux. When it comes to deploying your application, Spring Boot’s diverse packaging choices provide you with a lot of possibilities. Java Spring Boot applications can be deployed to a variety of cloud platforms, virtual/physical machines, or made fully executable for Unix systems.
The situations covered in this section are some of the most prevalent deployment scenarios. Spring Boot can be used in the same way as any other Java library. Simply add the necessary spring-boot-*.jar files to your classpath. Spring Boot does not require any specific tool integration, so you may use any IDE or text editor, and a Spring Boot application is no different than any other Java program in terms of running and debugging.
Although you may simply copy the Spring Boot jars, we recommend that you use a build tool that allows you to handle dependencies (such as Maven or Gradle).
It is also feasible to create fully executable applications for Unix systems in addition to executing Spring Boot applications with java -jar. This makes installing and managing Spring Boot apps in typical production contexts a breeze.
Below is Step-by-step guide to installing Java Spring Boot on Linux
Java Spring Boot is a popular open-source framework used for building web applications in Java. Spring Boot simplifies the process of building and deploying web applications by providing a range of features out of the box. In this article, we will provide a step-by-step guide on how to install Java Spring Boot on a Linux operating system.
Prerequisites: Before starting with the installation, ensure that you have the following prerequisites:
- A Linux machine with a supported operating system
- Java Development Kit (JDK) installed
- A command-line interface (terminal)
Step 1: Check Java Installation First, ensure that Java Development Kit (JDK) is installed on your system by running the following command in the terminal:
If you have JDK installed, you should see output similar to the following:
openjdk version "11.0.10" 2021-01-19 OpenJDK Runtime Environment (build 11.0.10+9-Ubuntu-0ubuntu1.20.04) OpenJDK 64-Bit Server VM (build 11.0.10+9-Ubuntu-0ubuntu1.20.04, mixed mode, sharing)
If JDK is not installed, you can install it using the following command:
sudo apt-get install default-jdk
Step 2: Install Spring Boot Spring Boot can be installed using the following command:
sudo apt-get install springboot
Step 3: Verify Spring Boot Installation Once the installation is complete, you can verify the installation using the following command:
You should see output similar to the following:
Spring CLI v2.4.4
Step 4: Create a Sample Spring Boot Application Now that Spring Boot is installed, let’s create a sample Spring Boot application to verify that everything is working properly.
Create a new directory for your application:
Change into the new directory:
Create a new Spring Boot application using the following command:
spring init --dependencies=web myapp
This command will create a new Spring Boot application with a web dependency.
Step 5: Run the Spring Boot Application After creating the application, you can run it using the following command:
cd myapp ./mvnw spring-boot:run
This command will start the Spring Boot application on the default port 8080.
Step 6: Test the Application To test the application, open a web browser and navigate to http://localhost:8080. You should see a “Whitelabel Error Page” indicating that the application is up and running.
Conclusion: In this article, we provided a step-by-step guide on how to install Java Spring Boot on a Linux operating system. By following these steps, you should now have a fully functional Spring Boot development environment ready to use.
Conclusion: installing Java Spring Boot on Linux
Congratulations! You have successfully installed Java Spring Boot on your Linux machine. In this guide, we walked through the step-by-step process of installing JDK, downloading and installing Spring Boot, and testing your installation with a simple “Hello World” application. With this foundation, you can now explore the vast possibilities of Spring Boot to create powerful and dynamic web applications.
