I've seen many incarnations of this same issue but I think I've tried all the fixes - my usage is quite straightforward.
I had been using Ehcache which also didn't work. So, to rule out Ehcache issues and help point to something more fundamental, I moved to SimpleCacheManager and ConcurrentMapCacheFactoryBean.
Here's my config:
<cache:annotation-driven/>
<bean id="cacheManager" class="org.springframework.cache.support.SimpleCacheManager">
<property name="caches">
<set>
<bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean" p:name="parentAppIds"/>
</set>
</property>
</bean>
Here's my method:
@Cacheable(value="parentAppIds", key="accountNumber")
public Long findApplicationId(String accountNsc, String accountNumber) throws EMSException {
....
}
This is a method on an interface, who's implementing class is Spring managed @Service("foo")
I tried using 'p0' as is suggested here but to no avail. I have no compilation problems and no errors in my server logs so I'm confident that I have all that is necessary on my classpath; and that Namespaces are all fine, since I'm using STS for that - so I left out pom.xml and spring Namespace declarations to block noise.
I'm using Spring 3.1; Java 1.5 and Websphere 6.1
The symptom is that the method is being visited with the same parameters repeatedly.
Please help - I'm hungry and refuse to go for lunch until I nail this.
note: I have simplified my @Cacheable declaration my actual one is
@Cacheable(value="parentAppIds", key="#p0.concat('-').concat(#p1)")
Neither work.
Thanks.
** Edit - I've ruled out Websphere as being a problem by creating a test rig with
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(...)
which mimics what is happening. @Cacheable
is simply not working. There must be something blindingly obvious that I am missing. (I've had lunch now)
My issue is resolved. Unfortunately I cannot pinpoint exactly where my issue lay. Certainly, all that is required is that which I have mentioned in my question.
TO fix this, I tidied up my Spring configuration a bit and cleared my browser and application server cache and temp directories. I did a full clean install and cache is now working.
It is possible that I was testing with an earlier version which did not include this important line in the application config:
<cache:annotation-driven/>
I had omitted that at the start. Maybe my adding of that was not picked up until now. Otherwise I am stumped. Thanks for your time.
