Understanding cache abstraction

Basically, caching in Java applications is applied to the Java methods to reduce the number of executions for the same information available in the cache. That means, whenever these Java methods are invoked, the cache abstraction applies the cache behavior to these methods based on the given arguments. If the information for the given argument is already available in the cache, then it is returned without having to execute the target method. If the required information is not available in the cache, then the target method is executed, and the result is cached and returned to the caller. Cache abstraction also provides other cache-related operations such as updating and/or removing the contents in the cache. These operations are useful when the data changes in the application sometimes.

Spring Framework provides cache abstraction for Spring applications by using the org.springframework.cache.Cache and org.springframework.cache.CacheManager interfaces. Caching...
