how to "ignore" @JsonIgnore while serializing?

I have a String attribute "version" in java class. I am using Jackson object mapper to serialize Java Class Object to JSON.

I am serializing same class for two use cases, 1) to store JSON value to key-value db store, and 2) to send response back to API call.

For first use case I need "version" attribute in serialized JSON and for second use case I don't need it to send back to user.

Using @JsonIgnore to version will not get me that attribute in both use cases.

I searched enough to see that is there any configuration I can set on Jackson mapper to ignore @JsonIgnore in some cases? No luck so far! Thanks for suggestions or workarounds in advance.

If you need to have multiple representations you can use @JsonView. 

public class Views {
    public static class Public {
    }

    public static class Private {
    }
}

public class User {
    public int id;

    @JsonView(Views.Public.class)
    public String name;
}

Do it in simple way, while in the second case set version to null and add this property on class level or property level

@JsonInclude(Include.NON_NULL)
