Spring Boot Web App

This is a simple Spring Boot web application. The application displays a "Welcome to Web App!" message and a button that, when clicked, shows a "Hello, World!" message.

Prerequisites

• Java 17
• Maven
• Docker (optional)
• Azure CLI (for deployment)
• Existing Azure Web App (for deployment)

Build and Run

1. Navigate to the project root directory (the same directory as the pom.xml file).
2. Run the following command to build the application:

mvn clean package

3. Run the following command to start the application:

mvn spring-boot:run

4. Open a web browser and navigate to http://localhost:8080 to access the web application.

Running with Docker (optional)

1. Build a Docker image of the application by executing the following command in the project root directory:

docker build --tag webapp .

2. Run a Docker container with the built image:

docker run --name webapp --rm --port 8080:8080 webapp

3. Access the web application at http://localhost:8080 in a web browser.

To stop the running container, find the container ID using docker ps, and then execute the command docker stop <container_id>.

Deploying to Azure App Services

1. Log in to your Azure account using the following command:

az login

2. Deploy the JAR file to the Web App:

az webapp deploy \
    --name <webapp-name> \
    --resource-group <resource-group-name> \
    --src-path target/webapp-0.0.1-SNAPSHOT.jar

Replace <WebAppName> with the name of your existing Azure Web App and <ResourceGroupName> with the name of the resource group associated with the web app.

3. Open a web browser and navigate to https://<WebAppName>.azurewebsites.net to access the web application, where <WebAppName> is the name of the existing web app.
