Disable Jackson mapper for a particular annotation

Question

With Jackson, it\'s easy to disable all annotations for a given ObjectMapper. Is there a way to only disable one given annotation?

I think it's a better idea to override findPropertiesToIgnore method like this:

    JacksonAnnotationIntrospector ignoreJsonTypeInfoIntrospector = new JacksonAnnotationIntrospector() {
        @Override
        public String[] findPropertiesToIgnore(AnnotatedClass ac) {
            ArrayList ret = new ArrayList();
            for (Method m : ac.getRawType().getMethods()) {
                if(ReflectionUtils.isGetter(m)){
                    if(m.getAnnotation(Transient.class) != null)
                        ret.add(ReflectionUtils.getPropertyName(m));

                }
            };
            return ret.toArray(new String[]{});
        }
    };
    objectMapper = new ObjectMapper();
    objectMapper.setAnnotationIntrospector(ignoreJsonTypeInfoIntrospector);
