Headers on admin

[kefayati]

I needed to set headers on the admin site, which is typically spun up on a different port and different servlets. Checking the code, it seems using environment.servlets() is hardcoded and there is no option to choose environment.admin() and add the header filter there. Is there a reason for that? It is a relatively simple fix and I am happy to do a PR to add that option but I was wondering if there is something I am missing.

@kefayati Sorry for the late reply.

This feature has been implemented in the latest releases of dropwizard-web:

bootstrap.addBundle(new WebBundle<>() {
    @Override
    public WebConfiguration getWebConfiguration(final ExampleConfiguration configuration) {
        return configuration.getWebConfiguration();
    }

    // Optional: Override Servlet environment to apply the configuration to the admin servlets
    @Override
    protected ServletEnvironment getServletEnvironment(Environment environment) {
        return environment.admin();
    }
});
