ObjectMapper with "jackson-module-afterburner": java.lang.IllegalStateException: Multiple definitions of method getBody found (original) (raw)

result :

Jackson version: 3.0.1 fail

interface A:

public interface A<T> {

     T getBody();
}

implements

public class MD implements A<String> {

    private String body;
    /**
     * @return
     */

    @Override
    public String getBody() {
        return body;

convert toJSON:

    public static void main(String[] args) {


        MD md = new MD();

        ObjectMapper objectMapper =
                JsonMapper.builder()

                     .build();
        String json = objectMapper.writeValueAsString(md);
        System.out.println(json);
    }
