我正在尝试在我的项目中添加(更新，插入)的自定义事件监听器。以下是我的代码片段。
hibernate.cfg.xml 文件条目:
<event type="post-insert">
<listener class="sample.org.app.MyProjectAdaptorHibEventListener"/>
</event>
<event type="save-update">
<listener class="sample.org.app.MyProjectAdaptorHibEventListener"/>
</event>
和MyProjectAdaptorHibEventListener实现代码片段:
public class MyProjectAdaptorHibEventListener implements PostInsertEventListener,
PostUpdateEventListener, PostDeleteEventListener,
SaveOrUpdateEventListener {
private static final long serialVersionUID = 400000L;
private MyProjectAdaptorHibEventListenerUtil util;
public MyProjectAdaptorHibEventListener() {
util = new MyProjectAdaptorHibEventListenerUtil();
System.out.println("************* MyProjectAdaptorHibEventListener loaded **************");
}
@Override
public void onPostDelete(PostDeleteEvent event) {
util.objectChanged("DELETE", event.getEntity());
}
@Override
public void onPostUpdate(PostUpdateEvent event) {
util.objectChanged("UPDATE", event.getEntity());
}
@Override
public void onPostInsert(PostInsertEvent event) {
util.objectChanged("INSERT", event.getEntity());
}
@Override
public void onSaveOrUpdate(SaveOrUpdateEvent event)
throws HibernateException {
util.objectChanged("SAVEORUPDATE", event.getObject());
}
}
和我的 MyProjectAdaptorHibEventListenerUtil 代码:
public class MyProjectAdaptorHibEventListenerUtil {
MyProjectAdaptorHibEventListenerUtil(){
}
public void objectChanged(String event, Object object) {
if (object instanceof AbstractDomainObject && ! object.getClass().getName().startsWith("edu.wustl.common.domain.Audit")) {
long objId = ((AbstractDomainObject) object).getId();
System.out.println("*********** " + event + " : " + object.getClass().getName()+ ":" + objId + " , value= " + object.toString());
insertIntoDB(event,object.getClass().getName(),objId);
}else{
// System.out.println("*********** " + event + " : " + object.getClass().getName());
}
}
}
我不确定我的代码有什么问题。请建议我进行更改。我收到以下错误。
我正在使用 hibernate 3 Jboss- 5.1.0 GA Java - 1.6

我认为你的xml有问题。据我所知，没有事件类型:
insert (至少在 hibernate v3.3 中没有)，但有以下类型(以及需要实现的接口(interface)):
"auto-flush"- AutoFlushEventListener
"merge", MergeEventListener
"create", PersistEventListener
"create-onflush", PersistEventListener
"delete", DeleteEventListener
"dirty-check", DirtyCheckEventListener
"evict", EvictEventListener
"flush", FlushEventListener
"flush-entity", FlushEntityEventListener
"load", LoadEventListener
"load-collection", InitializeCollectionEventListener
"lock", LockEventListener
"refresh", RefreshEventListener
"replicate", ReplicateEventListener
"save-update", SaveOrUpdateEventListener
"save", SaveOrUpdateEventListener
"update", SaveOrUpdateEventListener
"pre-load", PreLoadEventListener
"pre-update", PreUpdateEventListener
"pre-delete", PreDeleteEventListener
"pre-insert", PreInsertEventListener
"pre-collection-recreate", PreCollectionRecreateEventListener
"pre-collection-remove", PreCollectionRemoveEventListener
"pre-collection-update", PreCollectionUpdateEventListener
"post-load", PostLoadEventListener
"post-update", PostUpdateEventListener
"post-delete", PostDeleteEventListener
"post-insert", PostInsertEventListener
"post-commit-update", PostUpdateEventListener
"post-commit-delete", PostDeleteEventListener
"post-commit-insert", PostInsertEventListener
"post-collection-recreate", PostCollectionRecreateEventListener
"post-collection-remove", PostCollectionRemoveEventListener
"post-collection-update", PostCollectionUpdateEventListener
所以我认为你应该使用“插入后”，因为这种类型要求你的监听器实现 PostInsertEventListener(你实现的)
旧
我发现您收到的此异常的根本原因是 java.lang.ArrayStoreException，正如 javadoc 所述，它是
thrown to indicate that an attempt has been made to store the wrong type of object into an array of objects. For example, the following code generates an ArrayStoreException:
Object x[] = new String[3]; x[0] = new Integer(0);
请提供MyProjectAdaptorHibEventListener的来源
关于java - 添加自定义事件监听器(Hibernate)会引发 org.hibernate.MappingException : Unable to instantiate specified event (save-update) listener class，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11646111/
