JPA Callback not being called - spring

Question

I am new to hibernate. I want to know if any crud operation happens so I decided to use jpa callback annotations. The problem is any of those #PrePersist #PostPersist #PreRemove #PostRemove not being called when I run the project and use UI components to perform delete & add operations. I use primefaces datatable so delete operation bounded to a ManagedBean -> MessageService ->MessageDAO. IF I only execute the main file to test it it works perfectly
MessageDAO:
#Component
public class MessageDAO {
#PersistenceContext
private EntityManager em;
#Transactional
public void register(Message message) {
em.persist(message);
}
#Transactional
public void delete(Integer id) {
Message m = em.find(Message.class, id);
em.remove(em.merge(m));
}
}
MessageListener
public class MessageListener {
#PrePersist
public void prePersist(Message o) {
System.out.println("Pre-Persistiting operation: " );
}
#PostPersist
public void postPersist(Message o) {
System.out.println("Post-Persist operation: " );
}
#PreRemove
public void preRemove(Message o) {
System.out.println("Pre-Removing operation: " );
}
#PostRemove
public void postRemove(Message o) {
System.out.println("Post-Remove operation: " );
}
#PreUpdate
public void preUpdate(Message o) {
System.out.println("Pre-Updating operation: ");
}
#PostUpdate
public void postUpdate(Message o) {
System.out.println("Post-Update operation: " );
}
}
Message
#EntityListeners(MessageListener.class)
#Entity
#Table(name = "messages")
public class Message implements Serializable {
private Integer messageId;
private String subject;
private String content;
public Message(){}
public Message(Integer messageId, String subject, String content) {
this.messageId = messageId;
this.subject = subject;
this.content = content;
}
#Id
#GeneratedValue
#Column(name = "MESSAGE_ID")
public Integer getMessageId() {
return messageId;
}
//getter setter
#PrePersist
public void prePersist() {
System.out.println("OLDUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU!!!!!!!!!!!!");
}
}

Answer 1

As per the JPA spec, JPA callbacks/listeners are not called when using JPQL BULK DELETE. They are only called when using the JPA API (em.remove). Similarly the cache and managed entity objects do not reflect such a JPQL BULK DELETE call.

Answer 2

change Your code by following example hope it will work
#Transactional
public void delete(Long id) {
Message m = em.find(Message.class, id);
em.remove(em.merge(m));
}
}
