From the root of project directory (you will find pom.xml file there) run the following command

	mvn clean install

	java -jar target/simplechat-0.0.1.jar

You also use the following command

	mvn spring-boot:run

Note: confirm your maven is pointing to correct java version, in our case it should be JDK 1.8, you can do so by running

mvn --version

Test

The application will initialize some data from sample data set in import.sql in resource directory.

• Note: register and login request won't be filter with jwt. Other request required a valid token from successful login
