Log4j2 plugin not loaded in Spring 4 - spring

Question

While Spring 4 Rest application loading , i am getting the logger information ( log file name / path / archival days) from database and passing this value to Logj plugin , so that i can retrieve the value from log4j.xml.
My application log file not created and plugin not called ! not getting any error in console as well.
What should i do , for Logj plugin load and log file creation ?
Spring:4.3.15.RELEASE
log4j:2.4.1
java:1.8
SpringWebInitializer.java
public class SpringWebInitializer implements WebApplicationInitializer{
#Override
public void onStartup(ServletContext ctx) throws ServletException {
AnnotationConfigWebApplicationContext webCtx = new AnnotationConfigWebApplicationContext();
webCtx.register(WebConfiguration.class);
webCtx.setServletContext(ctx);
ServletRegistration.Dynamic servlet = ctx.addServlet("dispatcher", new DispatcherServlet(webCtx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
//Add Listener.
ctx.addListener(new MyAppContextListner());
}
}
WebConfiguration.java
#EnableWebMvc
#Configuration
#ComponentScan(basePackages ="org.vasa.ws.myapp")
public class WebConfiguration {
}
MyAppContextListner.java
public class MyAppContextListner implements ServletContextListener{
private static final Logger LOGGER = LogManager.getLogger(BenefitsCompositeContextListner.class);
private WebApplicationContext webApplicationContext = null;
#Override
public void contextInitialized(ServletContextEvent event) {
// Database connectivity and get the logger information from db.
}
#Override
public void contextDestroyed(ServletContextEvent event) {
// TODO Auto-generated method stub
}
}
Given below Log4j Plugin i am using
MyLog4JConfigDatabaseLookup.java
#Plugin(name = "MyAppdbLookup", category = StrLookup.CATEGORY)
public class MyLog4JConfigDatabaseLookup extends AbstractLookup {
public String lookup(final LogEvent event, final String key) {
System.out.println("Lookup......");
}

I have changed my plugin name as lower case and now it's working fine as expected:
#Plugin(name="myappdblookup")
