Jackson ignores private fields

class POJO {
  private int i;
  
  @JsonIgnore  
  public int getI() {
    return i + 1;
  }
}

class POJO {
  private int i;
  
  @JsonIgnore  
  public int getI() {
    return i + 1;
  }
}

this way the field i is completely ignored, can i somehow include it? tried mapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY); but that did not work

Why do you want to make it visible after explicitly ignoring it? Do you just not want jackson to call the getter?

KoblížkáčOP•6mo ago

yea the getter returns the value, but modified i want the serialized value to not be modified

I think you can configure it to use field access without @JsonIgnore

How to specify jackson to only use fields - preferably globally

Default jackon behaviour seems to use both properties (getters and setters) and fields to serialize and deserialize to json. I would like to use the fields as the canonical source of serialization

dan1st•6mo ago

set the field visibility to any and the getter visibility to none also with @JsonAutoDetect

Also, smarter approach: use a DTO, without a getter that modifies the value

dan1st•6mo ago

also that
