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 @cacheable. What am I doing wrong?

I've moved it into a junit test case with its own configuration file to isolate it from the rest of my application, but the problem still happens. Here are the relevant files:


<beans xmlns="http://www.springframework.org/schema/beans"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd">
<cache:annotation-driven />

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager" p:cache-manager-ref="ehcache"/>
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"


<diskStore path="java.io.tmpdir"/>
<cache name="cache"



public class MyTest extends TestCase {

    public void testCache1(){
        for(int i = 0; i < 5; i++){
            System.out.println("Calling someMethod...");

    private int someMethod(int val){
        System.out.println("Not from cache");
        return 5;

Relevant Pom entries: (spring-version = 3.1.1.RELEASE)


when I run the test, Spring puts out some debug messages that looks like my cache is initialized without errors

DEBUG: config.ConfigurationHelper - No CacheManagerEventListenerFactory class specified. Skipping...
DEBUG: ehcache.Cache - No BootstrapCacheLoaderFactory class specified. Skipping...
DEBUG: ehcache.Cache - CacheWriter factory not configured. Skipping...
DEBUG: config.ConfigurationHelper - No CacheExceptionHandlerFactory class specified. Skipping...
DEBUG: store.MemoryStore - Initialized net.sf.ehcache.store.MemoryStore for cache

DEBUG: ehcache.Cache - Initialised cache: cache
DEBUG: config.ConfigurationHelper - CacheDecoratorFactory not configured. Skipping for 'cache'.
DEBUG: config.ConfigurationHelper - CacheDecoratorFactory not configured for defaultCache. Skipping for 'cache'.

but the debug output shows no cache checks between method calls to someMethod and the print statement from inside someMethod prints every time.

Is there something I'm missing?

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 objectwill 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.


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.

In addition to this, you'll need to extract to an Interface so Spring can dynamically write a wrapper to your class.– RockMeetHardplace May 10 '12 at 1:01
