How do I migrate cache related annotations from Hibernate 3.3.x to 3.6.x

Question

My cache usage on entity Foo looked like this

@Entity
class Foo {

    @ManyToOne(fetch = LAZY)
    @Cache(usage = org.hibernate.annotations.CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
    private Boo boo;

    @OneToMany
    @Cache(usage = org.hibernate.annotations.CacheConcurrencyStrategy.READ_WRITE)
    private List<Bar> bars;
}

How should I migrate this code to support JPA 2 like annotations using Hibernate 3.6.5

I am aware that we are supposed to use @Cacheable annotation at the entity level, but what should I use for cache declarations under

@ManyToOne and @OneToMany.

JPA2 doesn't define caching specifics for fields/properties, just classes; JDO is the only persistence spec defining caching down to the field level — DataNucleus, Jun 23 '11 at 11:16

Remove your @Cache annotations and add to your persistence.xml :

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0">
  <persistence-unit name="FooPu" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    ...
    <shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>
    <properties>
      ...
      <property name="hibernate.cache.provider_class" value="org.hibernate.cache.SingletonEhCacheProvider"/>
      <property name="hibernate.cache.use_second_level_cache" value="true"/>
      <property name="hibernate.cache.use_query_cache" value="true"/>
    </properties>
  </persistence-unit>
</persistence>

No, sorry that doesn't answer the question. The question is asking about how to annotate collections for caching. — Dick Chesterwood, Jan 16 '13 at 18:37
