1. Package a WAR file
mvn package2. Rename the package name from JAR to WAR. The JAR still has WAR structure. The file has a JAR extension because of the maven-assembly-plugin. So, it's basically a JAR file with a WAR structure inside.
3. Run it.
java -jar exec-war.war4. Or deploy it in a web container, such as Tomcat.
