Spring Boot Rest API

Start the app

Using maven command

Navigate to the project directory and run:
mvn spring-boot:run

Specify Profile:
mvn spring-boot:run -Dspring-boot.run.profiles=h2
mvn spring-boot:run -Dspring-boot.run.profiles=postgres

Using java command

• Make sure to run mvn clean package so that jar file is available.
  java -Dspring.profiles.active=h2 -jar ./target/*.jar

Using mvnw command (is basically the same as using the mvn command)

./mvnw clean package -DskipTests
./mvnw spring-boot:run -Dspring-boot.run.profiles=h2

Serving static resources (html, external css, and image inside html)

My example (external css + image): http://localhost:8080/html_with_external_css_and_image.html
Basic html: http://localhost:8080/test.html
Basic html: http://localhost:8080/testB.html
