 DynamoDBMapperConfig config = DynamoDBMapperConfig.builder()
     .withTypeConverterFactory(DynamoDBTypeConverterFactory.standard().override()
         .with(String.class, MyObject.class, new StringToMyObjectConverter())
         .build())
     .build();
 

Then, on the property, specify the attribute binding,

 @DynamoDBTyped(DynamoDBAttributeType.S)
 public MyObject getMyObject()
