Spring Boot - Run a WAR which is injected as a dependency as a standalone JAR - spring

Question

I am trying to move a Spring WebMVC project to containerless architecture. I thought to start by having a simple Spring Boot project which only needs to start the embedded WAR file, and inject all the beans as normal. In my Application.java class, I have the following:
package demo.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
#SpringBootApplication
#ImportResource("classpath:beans/beans.xml")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
In my pom.xml, I have included the Spring WebMVC project as a dependency:
<dependency>
<groupId>com.other.app</groupId>
<artifactId>CoolWARApplication</artifactId>
<version>${app.version}</version>
</dependency>
My full pom:

<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
In my project structure in Eclipse, I can see this project and all of its dependencies being pulled in. However, when I start the Spring Boot app, I get the following error:
org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.
I'm not sure what I'm missing here. I thought that importing the WebMVC project as a dependency and injecting its beans into the Spring Boot application would run the project as normal, only inside a standalone JAR file. Is it advisable, or even possible, to do the above as described?
Thanks in advance.
