java.lang.Object net.sf.ehcache.hibernate.EhCacheProvider
@Deprecated public final class EhCacheProvider
Cache Provider plugin for Hibernate 3.2 and ehcache-1.2. New in this provider are ehcache support for multiple Hibernate session factories, each with its own ehcache configuration, and non Serializable keys and values. Ehcache-1.2 also has many other features such as cluster support and listeners, which can be used seamlessly simply by configurion in ehcache.xml.
Usehibernate.cache.provider_class=net.sf.ehcache.hibernate.EhCacheProvider
in the Hibernate configuration
to enable this provider for Hibernate's second level cache.
When configuring multiple ehcache CacheManagers, as you would where you have multiple Hibernate Configurations and
multiple SessionFactories, specify in each Hibernate configuration the ehcache configuration using
the property net.sf.ehcache.configurationResourceName
An example to set an ehcach configuration
called ehcache-2.xml would be net.sf.ehcache.configurationResourceName=/ehcache-2.xml
. If the leading
slash is not there one will be added. The configuration file will be looked for in the root of the classpath.
Updated for ehcache-1.2. Note this provider requires ehcache-1.2.jar. Make sure ehcache-1.1.jar or earlier
is not in the classpath or it will not work.
See http://ehcache.org for documentation on ehcache

public final long nextTimestamp()
public final boolean isMinimalPutsEnabledByDefault()
Indicates whether when operating in non-strict read/write or read-only mode Hibernate should optimize the access patterns for minimal puts or minimal gets. In Ehcache we default to minimal puts since this should have minimal to no affect on unclustered users, and has great benefit for clustered users.
This setting can be overridden by setting the "hibernate.cache.use_minimal_puts" property in the Hibernate configuration.
