This Maven project is a Spring boot implementation of a community Broadleaf Commerce application. It has many sensible defaults set up along with examples of how a fully functioning eCommerce site based on Broadleaf might work.
In general, it's recommended to run via the Spring Boot Maven Plugin mvn spring-boot:run or from an IDE.
