In this chapter, you go through the process of setting up your development environment for Spring Boot.

Required Tools

To get started with Spring Boot, you need to have the following tools installed on your system:

1. Java Development Kit (JDK) — Install the Latest Java JDK
2. Integrated Development Environment (IDE) — Use IntelliJ IDEA or Spring Tool Suite
3. Build Tool (Maven or Gradle) — Use Maven for a quick start

1. Java Development Kit (JDK)

Download JDK:

• Go to the official Oracle JDK download page or AdoptOpenJDK.
• Choose the latest version of JDK (Java 21 or later is recommended).

Install JDK:

• Follow the installation instructions specific to your operating system (Windows, macOS, or Linux).
• Set the JAVA_HOME environment variable to point to the JDK installation directory.

Verify Installation:

• Open a terminal or command prompt.
• Run the command: java -version
• Ensure the output shows the correct version of the JDK installed.

2. Integrated Development Environment (IDE)

Popular IDEs:

IntelliJ IDEA:

• Download and install IntelliJ IDEA from the official JetBrains website.
• Choose the Community Edition for free access or the Ultimate Edition for advanced features.

Download and install Spring Tool Suite IDE:

3. Build Tools (Maven or Gradle)

Maven Installation:

Download Maven:

• Go to the official Apache Maven website.
• Download the latest version of Maven.

Install Maven:

• Extract the downloaded archive to a directory of your choice.
• Set the M2_HOME environment variable to point to the Maven installation directory.
• Add the bin directory of Maven to the PATH environment variable.

Verify Installation:

• Open a terminal or command prompt.
• Run the command: mvn -version
• Ensure the output shows the correct version of Maven installed.

Gradle Installation:

Download Gradle:

• Go to the official Gradle website.
• Download the latest version of Gradle.

Install Gradle:

• Extract the downloaded archive to a directory of your choice.
• Set the GRADLE_HOME environment variable to point to the Gradle installation directory.
• Add the bin directory of Gradle to the PATH environment variable.

Verify Installation:

• Open a terminal or command prompt.
• Run the command: gradle -version
• Ensure the output shows the correct version of Gradle installed.

Once you install JDK, Maven and IntelliJ IDEA ( or STS), you can start building Spring Boot projects.

Conclusion

In this chapter, you learned how to set up the development environment for Spring Boot, including installing the JDK, IDE, and build tools.
