Unmodifiable Cache in EhCache

Question

I recently learned about Unmodifiable Map that returns an unmodifiable copy of the Map. Is there any such implementation that prevents the modification of data of Cache entries in EhCache?

Answer 1

There is no out of the box support for a read-only Cache in Ehcache 2.x or 3.x as I understand your request.

In Ehcache 2.x you could roll your own by using a cache decorator and then making them available to the CacheManager by using CacheManager.addDecoratedCache

In Ehcache 3.x there is no built-in support for decorated caches, so you would have to handle that yourself. Note that anyway since there is no longer a CacheManager singleton, this is not as bad as it sounds with regards to the way you would share the decorated cache with your application components.
