In this article, we want to show an example Maven pom.xml file configuration to use together:

  • Spring Boot 2.4
  • Tomcat 9 (JSP files, Servlet 4.0)
  • log4j2
  • Lombok
  • Hibernate + JPA + JPA 2 Metamodel Generator
  • MySQL
  • JUnit 4

  • WAR package output

Note: the below configuration enables automatic pre-compilation for Lombok and Metamodel Generator.

Run mvn clean install package to build the executable war file.
Run java -jar target/my-project.war to start Spring Boot Application (with Tomcat 9 that supports JSP files).

example pom.xml file:
