jackson 2 object to json ignore lazy loading

问题

I am using jackson 2 to parse an object to json format I am having problem when I parse lazy loading fields. I want to get a null reference if the object cannot be loaded.

How can I do that?

I want to discuss with you a solution and I want to know if there is a problem when I use it?

I have found that during parsing jackson uses getters method to get attributes So my solution is to modify the getters methods of lazy loading fields suppose that post is a lazy loaded field this is the getter of that fields

public Collection<Post> getPosts() {
        try{
            posts.size();
            return posts;
        }
        catch (Exception e){

        }
        return null;
    }

This solution is working fine but I don't know if it will cause future problems or not. We should also use @JsonInclude(JsonInclude.Include.NON_NULL) to ignore null fields.
