Hi everyone,
I'm running into an issue specifying custom region names for my 2nd level entity cache (not the query cache).
I have an entity annotated like below:
Code:
package com.package;
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY, region = "myCustomRegion")
public class MyEntity{
//Entity code goes here
}
Below is my hibernate session factory configuration (the memcached properties can be ignored for the purpose of this question IMO):
Code:
<prop key="hibernate.cache.provider_class">com.googlecode.hibernate.memcached.MemcachedCacheProvider</prop>
<prop key="hibernate.cache.use_query_cache">false</prop>
<prop key="hibernate.cache.use_second_level_cache">true</prop>
<prop key="hibernate.memcached.servers">cacheserver.com:11211</prop>
<prop key="hibernate.memcached.cacheTimeSeconds">300</prop>
Now the problem. It seems that the region name being used when hibernate loads and builds all the caches is the fully qualified entity name, which is the default behavior. From my example this would be "com.package.MyEntity". I was expecting it to use the custom region name I provided in the annotation "myCustomRegion". This is the log output (the last line shows the region name):
Code:

Am I going about this all wrong? Is what I'm trying to do even possible for the entity cache?
Your help is much appreciated. Thanks.
