Hi,

I have one customer entity A that has 3 value types (primary info, secondayr info and logistics info) and 4 java.util.Collection fields (one-to-many entities like shipping addresses, insurance details, creditcards etc). When Hibernate finds customer entity is dirty because any of 4 one-to-many entities is dirty, I would like to identifiy those dirty fields. How can I do that?

Thanks,
Tapshil

Enable Hibernate's logging to debug level and search for is dirty in the log. That will tell you exactly what property is detected to be dirty.

Thanks for the reply!

I forgot to mention that I need to know only dirty fields programmatically so that I can persist customer entity based on these dirty fields. For example, if my application finds that coverages field is modified, I don't want to persist customer entity in database. Below is my customer entity.

@Entity
@EntityListeners(value = { CustomListener.class })
@Table(name="MMGS_CUSTOMER")
@org.hibernate.annotations.Entity(
dynamicUpdate=true)
public class CustomerTO {

private Integer customerID;
private PrimaryTO primary;
private SecondaryTO secondary;
private Collection<InsuredCoverageTO> coverages = new ArrayList<InsuredCoverageTO>();
private Collection<PolicyOwnerTO> policyOwners = new ArrayList<PolicyOwnerTO>();
private Collection<ShipToInfoTO> shipping = new ArrayList<ShipToInfoTO>();
private Collection<PreferenceTO> preferences = new ArrayList<PreferenceTO>();
.....

Sorry, i made a mistake in explaining my requirement. Here is rephrased one:

I need to know only dirty fields so that I can do something based on these dirty fields. For example, if my application finds that coverages field is dirty, I would like to know that coverages field is one of the dirty fields. So, if coverages field is dirty, I need to marshall entire customer profile and send it to other application.
