Using Spring cache abstraction with Spring Data Redis
The cache abstraction of Spring Framework 3.1 applies caching to Java methods. When a cached method is called, the cache abstraction will check from the cache if the method has been called earlier by using the same parameters. If this is the case, then the return value is fetched from the cache and the method is not executed. Otherwise, the method is executed and its return value is stored in the cache.
Note
The cache abstraction of Spring Framework 3.1 is explained in more detail at http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/cache.html.
Spring Data Redis provides an implementation of the Spring cache abstraction. Using Redis as a cache has two benefits over using local caching implementations such as Ehcache:
It can be used as a centralized cache that is shared by each servlet container or application server that runs our application. This reduces the overall number of database queries, which reduces...
