Is there a way to create a Cache with different expiration times per-entry

I'd like to use Guava's Caching functionality, but from what I can tell, you can only evict entries based off of total size of the cache (number of entries) or a timed eviction (for the entire cache). I'd like to have some entries have different expiration times - so I can evict some entries after, say, 1 minute, and other entries after 10 minutes.

Is there some way to specify a field, or a function or something on a cache entry which will have it be evicted if its individual expiration has been passed?

No, there is not. This is so that expiration can be FIFO, rather than requiring an all-up priority queue.
