How can I deploy the war file to the embedded Tomcat server of the Spring boot application, which is offline INSIDE?

Question

I have a server module that depends on web modules:

 <dependency> <groupId>org.ema.server</groupId> <artifactId>web</artifactId> <version>0.0.1-SNAPSHOT</version> <type>war</type> </dependency> 

which gets repackaged using spring-boot-maven-plugin to get standalone:

 <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <fork>true</fork> <mainClass>org.ema.server.Server</mainClass> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> 

Everything is still working. The web module is included in the final bank as BOOT-INF/lib/web-0.0.1-SNAPSHOT.war .

I know that Spring allows you to load additional war files for Tomcat at run time , but it looks like such a war file should be located somewhere in the file system, or I'm doing it wrong.

The question is, how can I maintain a standalone feel, but can I still add war files to my final standalone jar and deploy them to the built-in Tomcat?

Below is the code that shows how to do this, but I'm not sure that this can be done the way I require it:

 @Bean public EmbeddedServletContainerFactory servletContainerFactory() { LOGGER.info("Adding web app"); return new TomcatEmbeddedServletContainerFactory() { @Override protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) { // Ignore that since it not working anyway. String resourcePath = getClass().getResource("/../lib/web-0.0.1-SNAPSHOT.war").getPath().toString(); try { tomcat.addWebapp("/web", resourcePath); } catch (ServletException ex) { throw new IllegalStateException("Failed to add webapp", ex); } return super.getTomcatEmbeddedServletContainer(tomcat); } }; }
