Spring 3.1 Cache Abstraction

Declarative Annotation based caching

• @Cacheable - This is the new & important annotation that allows methods to cache the fetched data.
• For each time when the method is triggered cache will check for the specific data.
• Spring 3.1 caching strategy allows users to cache data based on certain conditions also called as 'Conditional caching'.

• @CacheEvict annotation is very much useful to clear the unused data from the cache buffer.
• Finally spring annotations cannot enable themselves automatically we have to enable it explicitly, similarly for caching also we have to enable the caching annotations by providing the following tag in our configuration file.
