Explanation

Before deployment, package the Spring Boot application into an executable JAR file using Maven. This JAR contains the application and embedded Tomcat server.

Code:

mvn clean package

Explanation

Launch an AWS EC2 instance, connect to it using SSH, and install Java. The EC2 instance will host the Spring Boot REST API.

Code:

sudo apt update
sudo apt install openjdk-21-jdk

Explanation

Upload the generated JAR file to the EC2 instance using SCP or any file transfer tool.

Code:

scp target/student-api.jar ubuntu@EC2_PUBLIC_IP:/home/ubuntu/

Explanation

Run the Spring Boot application on the EC2 instance using the java -jar command. The embedded Tomcat server starts automatically.

Code:

java -jar student-api.jar

Explanation

Open the application port (for example, 8080) in the AWS Security Group. Clients can then access the REST API using the EC2 public IP address.

Code:

http://EC2_PUBLIC_IP:8080/students
