Tutorial Web Socket

# I run this with Maven and JDK 17 on an Ubuntu Server Virtual Machine
# Essentially you only need Maven and the repo.
# If you are running this in a local machine and have Maven and Java 17 installed, skip until step 6

# 1. Update and upgrade
sudo apt update -y
sudo apt upgrade -y

# 2. Just In case (optional)
sudo apt build-essential -y

# 3. When I cloned it today, Spring Boot Server Project was using for this Java version
# Install java 17
sudo apt install openjdk-17-jdk openjdk-17-jre -y

# 4. By default the WebSocket server port is 8080
# You need to open this ports
sudo ufw enable
sudo ufw allow 8080
sudo ufw allow 22 # in case you are using ssh

# 5. I used maven in order to run the server
sudo apt install maven

# 6. Clone the repo with git and go to the complete directory
git clone https://github.com/spring-guides/gs-messaging-stomp-websocket.git
cd complete

# 7. Run the websocket server
mvn spring-boot:run

# 8. Open the explorer in with url http://<IP-ADDRESS>:8080
# Example:
#     http://localhost:8080  - For localhost setup
#     http://192.168.0.18:8080 - For Virtual Machine
