HTTP session CacheProviderFacade implementation

[jeanphil]

Hi,

On BestCrosswords.com, I'm making heavy use of the EhCache implementation of the CacheProviderFacade and it's a delight to use, so thanks to the spring modules creators for writing it! I also wrote this blog post about it.

Recently, I had the need for a different kind of caching, one that would be closer to the logged in user so I decided to write a CacheProviderFacade that would use the HTTP session as data store. I wrote this blog post about the rationale behind it. It is a very rough implementation but it works. I attached it to this post in case it can be of any use to anyone.

If there's interest in including such an implementation in the next version of springmodules, let me know. I can clean up the code and make it a bit more customizable.

Ciao

Hi,

Would you be willing to post an example Spring configuration for your code?

It is meant to replace the cache provider facade bean. If you look at the spring-modules documentation for ehcache, you'll see something like that:

<bean id="cacheProviderFacade"
	class="org.springmodules.cache.provider.ehcache.EhCacheFacade">
	<property name="cacheManager" ref="cacheManager"/>
	<property name="failQuietlyEnabled" value="true"/>
</bean>

simply replace it with:

<bean id="cacheProviderFacade" class="com.bestcrosswords.ui.springmodules.caching.httpsession.HttpSessionCacheProviderFacade"		>
	<property name="failQuietlyEnabled" value="true"/>
</bean>

Then you can use the cache provider facade bean as you would if it were an ehcache facade.
