Launch Spring web application using Spring Boot - maven

Question

I am trying to launch an existing web application using Spring Boot, without changing my existing application at all and keeping the spring-boot specific stuff in a separate module. I have the following maven structure:
parent
web-app
boot-app
I want to launch the web-app from the boot-app.
My boot module
pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

Application.java:
#EnableAutoConfiguration
#ImportResource("classpath:WEB-INF/myApp-servlet.xml")
public class Application extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
My web module

<context:component-scan base-package="some.corp.name.space"/>
<mvc:annotation-driven />
</beans>
My Problem
When I run Application.java I get the following error:
Caused by: java.io.FileNotFoundException: class path resource [WEB-INF/myApp-servlet.xml] cannot be opened because it does not exist
at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:172)
at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:329)
... 24 more
From what I can see, this is because the maven-war-plugin only includes classes in the jar it creates and does not include the webapp directory.
My Question
Is there any way for me to achieve this, with or without the maven-war-plugin?
The most important thing for me is to have the boot-app as a separate module.
