You can do custom annotation processing by implementing springfox plugins .

If you implement the OperationBuilderPlugin interface springfox is providing you with all information you need.

@Component
@Order(SwaggerPluginSupport.SWAGGER_PLUGIN_ORDER)
public class OperationBuilderPluginImpl implements OperationBuilderPlugin {

    @Override
    public void apply(OperationContext context) {
        Optional<ApiOperation> methodAnnotation = context.findAnnotation(ApiSpecificationInfo.class);
        if (methodAnnotation.isPresent()) {
            ApiSpecificationInfo apiSpecificationInfo = methodAnnotation.get();
            // do your processing here
            context.operationBuilder().notes(apiSpecificationInfo.name());
        }
    }

    @Override
    public boolean supports(DocumentationType delimiter) {
        return SwaggerPluginSupport.pluginDoesApply(delimiter);
    }
}

See github for reference.
