D'oh! Sorry. You don't have a ProcessContext for Controller Services.
Controller Services' lifecycles are a bit different than
Processors and Reporting Tasks. For a Controller Service, you would
want to use the @OnEnabled annotation and then use the provided
ConfigurationContext:
private volatile SSLContextService sslContextService;
@OnEnabled
public void obtainControllerService(ConfigurationContext context) {
sslContextService =
context.getProperty(SSL_CONTEXT_SERVICE).asControllerService(SSLContextService.class);
}
Then you should be able to reference the sslContextService member variable from
whatever method that you need.
Does this make sense.
Thanks
