Spring 3.1 @Cacheable - method still executed

Question

I\'m trying to implement Spring 3.1 caching as explained here and here, but it doesn\'t seem to be working: my method is run through every time even though it is marked @cacheab

Answer 1

From http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/cache.html

In proxy mode (which is the default), only external method calls coming in through the proxy are intercepted. This means that self-invocation, in effect, a method within the target object calling another method of the target object, will not lead to an actual caching at runtime even if the invoked method is marked with @Cacheable - considering using the aspectj mode in this case.

and

Method visibility and @Cacheable/@CachePut/@CacheEvict

When using proxies, you should apply the @Cache annotations only to methods with public visibility.

1. You self-invoke someMethod in the same target object.
2. Your @Cacheable method is not public.
