What is the CacheDecoratorFactory used for, is it needed.

[Tony Evans]

Hi I have a Entity, I have configured as a cache Fund

@Entity(name = "Fund")
@Cache(usage=CacheConcurrencyStrategy.READ_WRITE, region="fund")
@Table(name = "Fund")
public class Fund {

I didnt want to create a cache fund, as I have nore entities to add so set up the default in my ehCache.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:noNameSpaceSchemaLocation="ehcache.xsd" updateCheck="true"
	monitoring="autodetect" dynamicConfig="true">

	<diskStore path="java.io.tmpdir" />

	<defaultCache maxElementsInMemory="10000" eternal="false"
		timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false"
		maxElementsOnDisk="10000000" diskPersistent="false"
		diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU">
	</defaultCache>
</ehcache>

This outputted the debug message

ConfigurationHelper - CacheDecoratorFactory not configured for defaultCache. Skipping for 'fund'.

I have no idea what this message means, but I assumed that skipping for fund, means its not being added to the CacheManager, sp i created an concrete object that extends CacheDecoratorFactory

<defaultCache maxElementsInMemory="10000" eternal="false"
		timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false"
		maxElementsOnDisk="10000000" diskPersistent="false"
		diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU">
		<cacheDecoratorFactory
			class="com.cav.spring.service.bank.cache.BankCacheDecoratorFactory"/>
	</defaultCache>

cache returns

name = org.hibernate.cache.spi.UpdateTimestampsCache status = STATUS_ALIVE eternal = false overflowToDisk = false maxEntriesLocalHeap = 10000 maxEntriesLocalDisk = 10000000 memoryStoreEvictionPolicy = LRU timeToLiveSeconds = 120 timeToIdleSeconds = 120 persistence = none diskExpiryThreadIntervalSeconds = 120 cacheEventListeners: ; orderedCacheEventListeners:  maxBytesLocalHeap = 0 overflowToOffHeap = false maxBytesLocalOffHeap = 0 maxBytesLocalDisk = 0 pinned = false ]

But properties is set to null.

So I took a guess and added Fund to the properties

<defaultCache maxElementsInMemory="10000" eternal="false"
		timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false"
		maxElementsOnDisk="10000000" diskPersistent="false"
		diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU">
		<cacheDecoratorFactory
			class="com.cav.spring.service.bank.cache.BankCacheDecoratorFactory"
			properties="name=com.cav.spring.service.bank.entity.Fund" />
	</defaultCache>

And got the following error

net.sf.ehcache.ObjectExistsException: Cache com.cav.spring.service.bank.entity.Fund already exists in the CacheManager

So now I have got to the point where I am confused. I have a feeling, I dont need a CacheDecoratorFactory,  to set up the fund cache, so I am not sure what the original debug  message skipping for fund means.

Thanks for any help. Tony
