How to ignore "Is' methods with Jackson 2.2.3

Question

A simple class has "is" methods and "get" methods. I would like Jackson to ignore calling all "is" methods.

I tried by setting ObjectMapper's visibility by setting as

mapper.setVisibility(PropertyAccessor.IS_GETTER, Visibility.NONE);

But it is still considering the is-getter methods, why?

Jackson serializes getter methods and public variables. Is it possible to indicate Jackson to call only public getter methods but not serialize variables?

As to your second question: yes, it is possible to prevent use of `public` variables; using `@JsonAutoDetect` or `mapper.setVisibility()`, similar to how getters/is-getters discovery may be prevented. — StaxMan, Mar 21 '14 at 05:14

You should consider @JsonAutoDetect annotation. For example, (using POJO class from this question: Conflicting getter definitions for property in Jackson 2.2.3 solution could look like this:

@JsonAutoDetect(isGetterVisibility = Visibility.NONE)
class GetterMethodsObject {

    private int id = 10;

    public int getId() {
        return id;
    }

    public boolean isId() {
        return true;
    }
}

Example usage:

ObjectMapper mapper = new ObjectMapper();
ObjectWriter objectWriter = mapper.writerWithDefaultPrettyPrinter();
System.out.println(objectWriter.writeValueAsString(new GetterMethodsObject()));

Above program prints:

{
  "id" : 10
}
