Handling of JAXB lists without setters

Hi guys,

Sorry if I am missing something.

JAXB doesn't generate setters for lists, as stated in the specification. We have to use getObjectList().add(object) to add a new object.

I am struggling finding a way to map lists, or the content of the lists inside PropertyMaps, as they are always looking for setters (as well as I know).

I was trying to create a converter before, but I have to use the PropertyMap because the source and the destination paths are completely different.

I will appreciate of you give me a direction...

Thanks in advance,

Ernesto Diaz

(I am using the latest stable version)

Hi Ernesto,

PropertyMap provides a methodology that you can use destination's getter to represent its property.

Like map(source.getSome(), destination.getOther());

But without setter, you need to enable field matching and set field access level.

Please try like following code snippet.

@Test
public class NoSetterTest1 extends AbstractTest {

  static class Source {
    private String str;

    public Source(String str) {
      this.str = str;
    }

    public String getStr() {
      return str;
    }

    public void setStr(String str) {
      this.str = str;
    }
  }

  static class Dest {
    private List<String> list;

    public List<String> getList() {
      return list;
    }
  }

  static class SplitConverter implements Converter<String, List<String>> {
    public List<String> convert(MappingContext<String, List<String>> context) {
      return Arrays.asList(context.getSource().split(","));
    }
  }

  public void shouldMap() {
    modelMapper.getConfiguration()
        .setFieldMatchingEnabled(true)
        .setFieldAccessLevel(Configuration.AccessLevel.PRIVATE);

    modelMapper.addMappings(new PropertyMap<Source, Dest>() {
      @Override
      protected void configure() {
        using(new SplitConverter()).map(source.getStr(), destination.getList());
      }
    });

    modelMapper.validate();

    assertEquals(modelMapper.map(new Source("a,b,c"), Dest.class).list,
        Arrays.asList("a", "b", "c"));
  }
}

Regards,

Chun Han

I don't know how many JAXB users there are, but if it's possible to solve this problem in a reusable way, it could make for a good integration.

Hi Chun,

First of all, thank you very much for your quick answer.

I performed the Unit test below and it worked fine for me. Then I replaces your classed with the ones that were generated and it worked well as well, so so far so good until now :)

I am happy I can continue with the introduction of your framework in the project :-)
