Question

I have the following project structure:

root
|---- web_1 (war)
|
|---- web_2 (war)
|
|---- common-security (jar)
|
|---- ear_1 (war_1 + common-security)
|
|---- ear_2 (war_2 + common-security)

In this common-security, I have added dependency of org.springframework:spring-web:5.0.9.RELEASE.

This is a sample implementation of WebApplicationInitializer which present in common-security:

import javax.servlet.ServletContext;
import javax.servlet.ServletException;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.web.WebApplicationInitializer;

public class MySecureWebApplicationInitializer implements WebApplicationInitializer {

    private final Logger logger = LogManager.getLogger(getClass());

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        logger.info("m");
    }
}

Each ear contain a war file and the common-security jar. The common-security jar is added in the Class-Path in the META-INF/MANIFEST.MF of the war module. Each of the war file contains web.xml and my servlet version is 3.1.

When I hit the landing page I see:

No Spring WebApplicationInitializer types detected on classpath

But if I duplicate the implementation of WebApplicationInitializer in any war module and remove the dependency of common-security, from that module I see it detects one WebApplicationInitializer and logs the designated message.

I need to have one common module of spring and security which will be used by two different wars.

Any pointer would be great.

Implementation of WebApplicationInitializer not loaded from library jar
