The only working way we found was this:
package something;
import java.io.Serializable;
import java.util.Collections;
import java.util.Set;
import java.util.stream.Collectors;
import org.hibernate.envers.DefaultRevisionEntity;
import org.hibernate.envers.EntityTrackingRevisionListener;
import org.hibernate.envers.RevisionType;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.google.inject.Inject;
...
public class AuditListener implements EntityTrackingRevisionListener {
private static final Logger log = LoggerFactory.getLogger(AuditListener.
class);
@Inject
private RevMasterChangeDAO revMasterChangeDAO;
public AuditListener() {
super();
// this is not created by guice but somehow instatiated by
hibernate envers
// therefore injection does not work out of the box
// the following statement injects manually all members in this.
// TODO find a better way to integrate this in guice
try {
InjectorHolder.getInjector()
.injectMembers(this);
} catch (Exception e) {
log.warn(e.getMessage(), e);
}
}
public AuditListener(boolean dontInject) {
super();
// use this constructor for tests, if mocks are injected with and
via mockito
}
snip
InjectorHolder looks like this:
/**
* Holds instance of the Guice injector. Should be filled after
initialization
* of Injector (after calling createInjector())
*/
public final class InjectorHolder {
private static Injector staticInjector;
private InjectorHolder() {
}
public static void setInjector(Injector injector) {
staticInjector = injector;
}
public static Injector getInjector() {
return staticInjector;
}
