[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3117) Proposal for better (more speaking) Exceptions
Proposal for better (more speaking) Exceptions
----------------------------------------------
Key: HHH-3117
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3117
Project: Hibernate3
Issue Type: Improvement
Components: core
Affects Versions: 3.2.5
Reporter: Daniel Migowski
Priority: Minor
Currently I get LazyInitializationExceptions in my Logfiles. To debug them, it would be
great to know from with lazy objects they originate. To achive this I currently override
the AbstractLazyInitializer class and add the entityName and Id to the ExceptionText. The
modified source is like this (Just the exception messages have been modified):
public final void initialize() throws HibernateException {
if (!initialized) {
if ( session==null ) {
throw new LazyInitializationException("could not initialize proxy for
"+entityName+"("+id+") - no Session");
}
else if ( !session.isOpen() ) {
throw new LazyInitializationException("could not initialize proxy for
"+entityName+"("+id+") - the owning Session was closed");
}
else if ( !session.isConnected() ) {
throw new LazyInitializationException("could not initialize proxy for
"+entityName+"("+id+") - the owning Session is disconnected");
}
else {
target = session.immediateLoad(entityName, id);
initialized = true;
checkTargetState();
}
}
else {
checkTargetState();
}
}
private void checkTargetState() {
if ( !unwrap ) {
if ( target == null ) {
getSession().getFactory().getEntityNotFoundDelegate().handleEntityNotFound( entityName, id
);
}
}
}
public final void setSession(SessionImplementor s) throws HibernateException {
if (s!=session) {
if ( isConnectedToSession() ) {
//TODO: perhaps this should be some other RuntimeException...
throw new HibernateException("illegally attempted to associate a
proxy for "+entityName+"("+id+") with two open Sessions");
}
session = s;
}
}
