How can I cache the result?
Hi everybody!
I want to add cache function to the web services.It's my code
@GET
@Path("/bookCategory")
@Produces(MediaType.APPLICATION_XML)
public List<EBookCategory> bookCategory() {
List<EBookCategory> categorys=...get from db;
return categorys;
}
but I don't want just cache the db result,I want to cache the final result(the xml generate by wink),how can I do it?
I'm using memcached and Simple-Spring-Memcached to do it.
thanks!

Hi,
Take a look at Ehcache
http://ehcache.org/documentation/user-guide/web-caching

It's been a while since I tried to do this, but I'm assuming you need to be caching this not in Wink but in whatever HTTP/servlet container you're using. So by caching in the container, you're avoiding a lot of the URI targeting/resource instantiation work. It's possible some of this caching capability has been built into Wink since last I looked, but I didn't remember it being there.
I'm admittedly not the best at remembering the nuance of the various HTTP caching headers, but if you use the JAX-RS apis to set the appropriate lifetime for the resource, it's possible your container (or a proxy sitting in front of Wink) would see that and know what to do with it. Just a thought...

Thanks for replay.
But I konw the principle of cache,and I
konw I can use Ehcache or
memcached.
I want to use memcached.
@GET
@Path("/bookCategory")
@Produces(MediaType.APPLICATION_XML)
public List<EBookCategory> bookCategory() {
//here I can add cache code
List<EBookCategory> categorys=getFromCache()==null?getFromDb():getFromCache();
return categorys;
}
this way I just cache the result from db,and I still waste my cpu on parse
the object to xml,I want to cache the xml,but this is done by the wink.
How can I cache the result generate by wink?
