Every time I call JPA method its creating entity and binding query.
My persistence
properties are:
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
<property name="hibernate.cache.provider_class" value="net.sf.ehcache.hibernate.SingletonEhCacheProvider"/>
<property name="hibernate.cache.use_second_level_cache" value="true"/>
<property name="hibernate.cache.use_query_cache" value="true"/>
And I am creating entity manager the way shown below:
emf = Persistence.createEntityManagerFactory("pu");
em = emf.createEntityManager();
em = Persistence.createEntityManagerFactory("pu").createEntityManager();
Is there any nice way to manage entity manager resource instead create new every time or any property can set in persistence. Remember it's JPA.
See below binding log every time :
