-------------------------------------
Hi Steve,
I had a similar issue on JBoss AS7 (default provider=Hibernate4) with {{@Cacheable}} on a
JPA entity and the property {{<property
name="javax.persistence.sharedCache.mode" value="ALL"/>}} (or any
other value) in {{persistence.xml}}: the L2 entity cache does not work.
But if you use {{<shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>}} in
the {{<persistence-unit>}} tag instead of the {{javax.persistence.sharedCache.mode}}
property, and add the property {{<property
name="hibernate.cache.use_second_level_cache" value="true"/>}}, the
L2 entity cache works. See [my answer to Paul Bakker's
post|https://forum.hibernate.org/viewtopic.php?p=2450594#p2450594].
So maybe that's not the {{@Cacheable}} annotation which does not work, but the
{{javax.persistence.sharedCache.mode}} property.
@Cachable has no effect
-----------------------
Key: HHH-5303
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5303
Project: Hibernate Core
Issue Type: Bug
Components: caching (L2), entity-manager
Affects Versions: 3.5.2
Environment: Tested on HSQL (included in testcase) and MySQL database
Reporter: Paul Bakker
Attachments: testcase.zip
The JPA 2.0 @Cachable annotation has no effect at all. Just putting @Cachable on a class
is not enough to enable caching. You must also configure a concurrency strategy with
either @Cache or a hibernate.ejb.classcache setting in persistence.xml.
If those settings are in place, @Cacheble still has no effect. Entities are cached, but
@Cachable(false) doesn't change this behavior.
I included a Maven example project that tests this behavior. The project has two profiles
to switch between Hibernate and EclipseLink:
mvn -P hibernate clean test
mvn -P eclipselink clean test
