Ralph Goers commented on LOG4J2-359:
------------------------------------
Nick, Log4jServletContainerInitializer is adding Log4jServletContextListener as
a listener but then appears to act as if its contextInitialized method is not
going to be called. From my reading and in looking at
http://svn.apache.org/repos/asf/tomcat/trunk/test/org/apache/catalina/startup/TestListener.java
that doesn't appear to be the case. Shouldn't the onStartup method look like:
{code}
@Override
public void onStartup(final Set<Class<?>> classes, final ServletContext
servletContext) throws ServletException {
servletContext.log("Log4jServletContainerInitializer starting up Log4j
in Servlet 3.0+ environment.");
servletContext.addListener(new Log4jServletContextListener());
final FilterRegistration.Dynamic filter =
servletContext.addFilter("log4jServletFilter", new Log4jServletFilter());
filter.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class),
false, "/*");
}
{code}
Of course, if the user also configures the ServletContextListener in web.xml
also then it will still try to initialize and destroy twice, but that can be
handled pretty easily.
