杰克逊不能告诉哪个吸气者是＆＃34;对＆＃34;一。您可以告诉它忽略以下两种方法之一：

public interface DynamoAttributeValueHack {
  @JsonIgnore
  public boolean isNull();

  @JsonIgnore
  public boolean isBOOl(); // You may need this as well depending on your AWS library version.
}

myMapper.addMixInAnnotations(AttributeValue.class, DynamoAttributeValueHack.class)
