Jackson's Access.WRITE_ONLY during test null

Question

I\'m currently playing around with Jackson\'s de/serialization features and I encountered a problem, I don\'t know how to solve.

During my test the @JsonProper

Answer 1

I had the same problem, with a similar setup. The problem is in the test input data. Basically, writeValueAsBytes() will ignore the password while serializing exactly as instructed by the annotation.

Note that, Access.WRITE_ONLY basically means "SetterOnly" or "DeserializationOnly" not the other way around.

Answer 2

add the line for your ObjectMapper:

mapper.disable(MapperFeature.USE_ANNOTATIONS);

Answer 3

Ignoring all the annotations can be problematic. To handle a finer configuration you can implement your custom JacksonAnnotationIntrospector:

public class IgnoreJacksonWriteOnlyAccess extends JacksonAnnotationIntrospector {

    @Override
    public JsonProperty.Access findPropertyAccess(Annotated m) {
        JsonProperty.Access access = super.findPropertyAccess(m);
        if (access == JsonProperty.Access.WRITE_ONLY) {
            return JsonProperty.Access.AUTO;
        }
        return access;
    }
}

Then, after instantiating the mapper:

mapper.setAnnotationIntrospector(new IgnoreJacksonWriteOnlyAccess());
