I am trying out the
@Cacheable annotation support for Spring 3.1 and wondering if there is any way to make the cached data clear out after a time by setting a TTL?
Right now from what I can see I need to clear it out myself by using the
@CacheEvict, and by using that together with
@Scheduled I can make a TTL implementation myself but it seems a bit much for such a simple task?
How can I set the TTL/TTI/Eviction policy/XXX feature?
Directly through your cache provider. The cache abstraction is... well, an abstraction not a cache implementation
So, if you use EHCache, use EHCache's configuration to configure the TTL.
You could also use Guava's CacheBuilder to build a cache, and pass this cache's ConcurrentMap view to the setStore method of the ConcurrentMapCacheFactoryBean.
