Can't make Jackson and Lombok work together

Question

I am experimenting in combining Jackson and Lombok. Those are my classes:

package testelombok;

import com.fasterxml

If you want immutable but a json serializable POJO using lombok and jackson. Use jacksons new annotation on your lomboks builder @JsonPOJOBuilder(withPrefix = "") I tried this solution and it works very well. Sample usage

import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.databind.annotation.JsonPOJOBuilder;
import lombok.Builder;
import lombok.Value;

@JsonDeserialize(builder = Detail.DetailBuilder.class)
@Value
@Builder
public class Detail {

    private String url;
    private String userName;
    private String password;
    private String scope;

    @JsonPOJOBuilder(withPrefix = "")
    public static class DetailBuilder {

    }
}

If you have too many classes with @Builder and you want don't want the boilerplate code empty annotation you can override the annotation interceptor to have empty withPrefix

mapper.setAnnotationIntrospector(new JacksonAnnotationIntrospector() {
        @Override
        public JsonPOJOBuilder.Value findPOJOBuilderConfig(AnnotatedClass ac) {
            if (ac.hasAnnotation(JsonPOJOBuilder.class)) {//If no annotation present use default as empty prefix
                return super.findPOJOBuilderConfig(ac);
            }
            return new JsonPOJOBuilder.Value("build", "");
        }
    });

And you can remove the empty builder class with @JsonPOJOBuilder annotation.
