Anticipating Ales' work on the optimization between HEM and the micro container
( http://opensource.atlassian.com/projects/hibernate/browse/HHH-4191 ),
I've added a way to pass an instance of Scanner to the persistence unit:
- an actual instance (recommended)
- the class name of the instance to use
Use the hibernate.ejb.resource_scanner property name
(HibernatePersistence.SCANNER)
In our case, the JPA deployer needs to add the following property
Map<String, Object> properties = new HashMap<String, Object>(1);
properties.put( HibernatePersistence.SCANNER, mcScannerInstance);
persistenceProvider.createContainerEntityManagerFactory(persistenceUnitInfo,
properties);
I've also changed part of the Scanner interface from
/**
* return all files in the classpath (ie PU visibility) matching one of
these file names
* if filePatterns is empty, return all files
* the use case is really exact file name.
*/
Set<NamedInputStream> getFilesInClasspath(URL jartoScan, Set<String>
filePatterns);
to
/**
* Return all files in the classpath (ie PU visibility) matching one of
these file names
* if filePatterns is empty, return all files
* the use case is really exact file name.
*
* NOT USED by HEM at the moment. We use exact file search via
getResourceAsStream for now.
*/
Set<NamedInputStream> getFilesInClasspath(Set<String> filePatterns);
