Hi all and thanks for your time. I've run into a little trouble with auto-generating java.util.UUIDs.

Consider the following entity:

@javax.persistence.Entity
@javax.persistence.Table(name="clients")
public class Client {
    @javax.persistence.GeneratedValue
    @javax.persistence.Id
    private UUID id;

    public UUID getId() {
        return id;
    }
}

When attempting to persist a new instance, I get the following stacktrace:

javax.persistence.PersistenceException: org.hibernate.id.IdentifierGenerationException: unrecognized id type : uuid-binary -> java.util.UUID

I've seen many solutions that involve the use of @GenericGenerator. If the model is supplied by a vendor and cannot be modified, how then may I rectify the situation. I have come across snippets which suggest I might be able to register a default generator through the SessionFactory, but I've yet to determine how.

Any help is much appreciated.

Edit:

I did some digging through the sources indicated by the trace, and I came to this section in org.hibernate.id.IdentifierGeneratorHelper:

Class clazz = type.getReturnedClass();
if (rs.getMetaData().getColumnCount() == 1) {
    if ( clazz == Long.class ) {
        return rs.getLong( 1 );
    }
    else if ( clazz == Integer.class ) {
        return rs.getInt( 1 );
    }
    else if ( clazz == Short.class ) {
        return rs.getShort( 1 );
    }
    else if ( clazz == String.class ) {
        return rs.getString( 1 );
    }
    else if ( clazz == BigInteger.class ) {
        return rs.getBigDecimal( 1 ).setScale( 0, BigDecimal.ROUND_UNNECESSARY ).toBigInteger();
    }
    else if ( clazz == BigDecimal.class ) {
        return rs.getBigDecimal( 1 ).setScale( 0, BigDecimal.ROUND_UNNECESSARY );
    }
    else {
        throw new IdentifierGenerationException(
            "unrecognized id type : " + type.getName() + " -> " + clazz.getName()
        );
    }
}

At a glance, unless I'm missing something higher up in the chain, there seems to be no way of returning anything other than a primitive as a generated id.

Further Edit:

The column type in the database was incorrect. Fixing it did not rectify the problem. I did however notice that if I generate the UUID myself using java.util.UUID.randomUUID that Hibernate persists the ID correctly. At this point I'm marching forward with application-generated UUIDs, but I'd like to find out why I've been having this problem. Alternatively, I'm willing to entertain reasons why I shouldn't bother with letting Hibernate generate the uuids.

You might also declare a generator in a package-info.java file and then use it via the @GeneratedValue annotation on the id field.

package-info.java:

@org.hibernate.annotations.GenericGenerator(
        name = "UUID",
        strategy = "org.hibernate.id.UUIDGenerator"
)
package org.leanhis.patientmanagement;

PatientEntity.java:

public class PatientEntity implements Patient {

    @Id
    @GeneratedValue(generator = "UUID")
    @Column
    private UUID id;

So the clue lies a few lines above the org.hibernate.id.IdentifierGeneratorHelper snippet you quoted:

if ( ResultSetIdentifierConsumer.class.isInstance( type ) ) {
        return ( ( ResultSetIdentifierConsumer ) type ).consumeIdentifier( rs );
    }

In your case you could create a custom ID type that implements UserType and ResultSetIdentifierConsumer. See this tutorial
