Integrating Spring boot war inside ear along with other war's

Question

I have created zuul proxy application using spring boot and I am able to deploy it as a spring boot and war in Wildfly server by making some changes in pom and SpringApplication class file.

Structure of my ear :

  MyEE.ear
  |
  |__gatewayzull.war
        |_WEB-INF/lib/all jar for spring boot application
  |
  |__EJB.jar
  |
  |__XX.war
  |
  |lib/all jar (which also includes spring jars)

I have done some changes in pom.xml to deploy spring application war in WildFly server and It is working as expected.

When I tried to add gatewayzull.war in MyEE.ear and deploy it in Wildfly server, I am getting this exception

WildFly was trying to start Gatewayapplication but failed to start it.

jar inside gatewayzull.war.WEB-INF.lib not loaded. deployment.MyEE.ear.lib also has spring related jar. I have added exclusion tag in jboss-deplyment-structure.xml inorder to exclude while loading but this also did not helps.

Snipper of jboss.xml :

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
        ..
        ..
        <sub-deployment name="gateway.war">
        <exclusions>
            <module name="deployment.MyEE.ear.XX.war" />
            <module name="deployment.MyEE.ear.EJB.jar" />
            <module name="deployment.MyEE.ear.lib" />
            <module name="javax.ws.rs.api" />
        </exclusions>
        <exclude-subsystems>
            <subsystem name="jaxrs" />
        </exclude-subsystems>
    </sub-deployment>
</jboss-deployment-structure>

I am assuming that core issue would be due to application server not able to load jar inside war/web-inf/lib and in turn server not intializing SpringBootServeletIntializer.

Any idea to resolve this ?
