Spring Boot - Spring Boot FreeMarker War packaging

The following example shows how to package FreeMarker based Spring Boot application as war so that it can be deployed to a Servlet container server. Also check out our FreeMarker Jar packaging Boot tutorial here.

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

Boot main config class

@SpringBootApplication
public class ExampleMain extends SpringBootServletInitializer {
  @Override
  protected SpringApplicationBuilder configure (SpringApplicationBuilder builder) {
      return builder.sources(ExampleMain.class);
  }

  public static void main(String[] args) throws InterruptedException {
      SpringApplication.run(ExampleMain.class, args);
  }
}

To run as war via tomcat maven plugin (included in pom.xml):

mvn tomcat7:run-war
