Spring: hibernate + ehcache

Question

I\'m working with a spring project using hibernate and look to implement second-level cache using ehcache. I see a number of approaches to this:

1. spring-mod

Answer 1

Our project uses option 3. We apply annotation org.hibernate.annotations.Cache to entities that we cache in an Ehcache, configure Ehcache using ehcache.xml, and enable and configure the Hibernate second-level cache in hibernate.cfg.xml:

    
    
        net.sf.ehcache.hibernate.EhCacheProvider
    
    
        net.sf.ehcache.hibernate.EhCacheRegionFactory
    
    true
    true
    true     
    true

For most entities, we use cache concurrency strategy CacheConcurrencyStrategy.TRANSACTIONAL:

@Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)

Our Maven project uses Hibernate 3.3.2GA and Ehcache 2.2.0:

    
        net.sf.ehcache
        ehcache-core
        2.2.0
    
    
        org.hibernate
        hibernate-core
        3.3.2.GA
    
    
        org.hibernate
        hibernate-commons-annotations
        3.3.0.ga
        
            
                net.sf.ehcache
                ehcache
            
        
    
    
        org.hibernate
        hibernate-annotations
        3.2.1.ga
    
    
        org.hibernate
        ejb3-persistence
        3.3.2.Beta1
