I'm not sure how you hook this in with Spring, but below is a description of the JAXB mechanism that you can leverage.

If you have the following:

@javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter(value=RoundingAdapter.class,type=java.math.BigDecimal.class)

Then using the standalone JAXB APIs you could do the following. The code below means whenever the RoundingAdapter is encountered, the specified instance should be used.

marshaller.setAdapter(new RoundingAdapter(4));
unmarshaller.setAdapter(new RoundingAdapter(4));
