John D. Ament reassigned DELTASPIKE-1157:
-----------------------------------------
Assignee: John D. Ament
> Repository.findBy methods do not allow an override to add query hints.
> ----------------------------------------------------------------------
>
> Key: DELTASPIKE-1157
> URL: https://issues.apache.org/jira/browse/DELTASPIKE-1157
> Project: DeltaSpike
> Issue Type: New Feature
> Components: Data-Module
> Affects Versions: 1.5.3
> Reporter: Amita Mehta
> Assignee: John D. Ament
>
> We need a way to to add hints or a property override to the findBy methods
> for the primary key to prevent reading stale data .
> We tried overriding the findBy with query hints but these are ignored by the
> DelatSpike Data Module EntityRepositoryHandler .
> @Override
> @Query(hints = {@QueryHint(name = "javax.persistence.cache.retrieveMode",
> value = "BYPASS"), @QueryHint(name = "eclipselink.refresh",
> value = "TRUE")})
> public ENTITY findBy(PK primaryKey);
> The only thing that works is creating a custom query in the repository that
> uses override properties –
> public AgentDE findByPK(final String primaryKey) {
> final Map<String, Object> properties = new HashMap<String, Object>();
> properties.put("QueryHints.CACHE_USAGE", CacheUsage.DoNotCheckCache);
> properties.put("eclipselink.refresh", "true");
>
> entityManager().getEntityManagerFactory().getCache().evict(entityClass(),
> primaryKey);
> entityManager().clear();
> return entityManager().find(entityClass(), primaryKey, properties);
> }
