com.haulmont.cuba.core.app.events.EntityPersistingEvent<E>

Type Parameters:

E - entity type

All Implemented Interfaces:

java.io.Serializable, org.springframework.core.ResolvableTypeProvider

public class EntityPersistingEvent<E extends Entity>
extends org.springframework.context.ApplicationEvent
implements org.springframework.core.ResolvableTypeProvider

A Spring application event of the middle tier that is sent before a new entity instance is persisted in the data store.

You can use @EventListener annotation on a bean method to handle this event. The handler works inside the transaction which is going to persist the entity. The entity instance is in the NEW state.

Example of event handler:

  @Component("test_OrderPersistingListener")
 public class OrderPersistingListener {

      @EventListener
     protected void orderPersisting(EntityPersistingEvent<Order> event) {
         Order order = event.getEntity();
         //...
     }
 }
