    copied!<p>im trying to build a spring (3.1) &amp; hibernate (3.6.10) web application and having a problem with the hibernate events. I implemented my own DefaultSaveOrUpdateEventListener for updating/creating a dateCreated and lastUpdated date which is called on every .saveOrUpdate() event. So far so good.</p> <p>Shouldn't this listener be called also on .save() or .update() events? Or am i missing something here?</p> <p>Listener:</p> <pre><code>public class SaveOrUpdateDateListener extends DefaultSaveOrUpdateEventListener { private static final long serialVersionUID = 1L; private static Logger log = Logger.getLogger(SaveOrUpdateDateListener.class); @Override public void onSaveOrUpdate(SaveOrUpdateEvent event) { log.debug("Entered onSaveOrUpdate()"); if (event.getObject() instanceof BaseDomain) { BaseDomain record = (BaseDomain) event.getObject(); record.setDateUpdated(new Date()); if (record.getDateCreated() == null) { record.setDateCreated(new Date()); } } super.onSaveOrUpdate(event); } } </code></pre> <p>Hibernate config (partially):</p> <pre><code>&lt;sesssion-factory&gt; &lt;event type="save-update"&gt; &lt;listener class="net.test.listener.hibernate.SaveOrUpdateDateListener"/&gt; &lt;listener class="org.hibernate.event.def.DefaultSaveOrUpdateEventListener"/&gt; &lt;/event&gt; &lt;/session-factory&gt; </code></pre> <p>example dao methods (<strong>doesn't work</strong>):</p> <pre><code>@Autowired private SessionFactory sessionFactory; @Override public void add(Registration registration) { sessionFactory.getCurrentSession().save(registration); } @Override public void update(Registration registration) { sessionFactory.getCurrentSession().update(registration); } </code></pre> <p>example dao methods (<strong>works</strong>):</p> <pre><code>@Autowired private SessionFactory sessionFactory; @Override public void add(Registration registration) { sessionFactory.getCurrentSession().saveOrUpdate(registration); } @Override public void update(Registration registration) { sessionFactory.getCurrentSession().saveOrUpdate(registration); } </code></pre> <p><br> <br> <strong>Edit</strong></p> <p>After i dedcided not to use saveOrUpdate in general i hopefully solved my problem with using a base class like the following:</p> <pre><code>@MappedSuperclass public class BaseDomain { @Id @GeneratedValue protected Integer id; @Column(nullable=false) protected Timestamp dateCreated; @Column(updatable = false, insertable = false, columnDefinition = "timestamp default current_timestamp on update current_timestamp") @Generated(GenerationTime.ALWAYS) protected Timestamp dateUpdated; protected BaseDomain() { this.dateCreated = new Timestamp(System.currentTimeMillis()); } public Integer getId() { return id; } protected void setId(Integer id) { this.id = id; } public Timestamp getDateCreated() { return dateCreated; } public Date getDateUpdated() { return dateUpdated; } } </code></pre> <p>As the current_timestamp can be used only once per table (mysql restriction) i tried to build the dateCreated via constructor.</p>
