I tried some new Spring features and I found out that @CachePut and @CacheEvict annotations has no effect. May be I do something wrong. Could you help me?
My applicationContext.xml.
<cache:annotation-driven />
<!--also tried this-->
<!--<ehcache: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"
p:config-location="classpath:ehcache.xml"/>
This part works well.
@Cacheable(value = "finders")
public Finder getFinder(String code)
{
return getFinderFromDB(code);
}
@CacheEvict(value = "finders", allEntries = true)
public void clearCache()
{
}
But if I want remove single value from cache or override it I can't do that. What I tested:
@CacheEvict(value = "finders", key = "#finder.code")
public boolean updateFinder(Finder finder, boolean nullValuesAllowed)
{
// ...
}
/////////////
@CacheEvict(value = "finders")
public void clearCache(String code)
{
}
/////////////
@CachePut(value = "finders", key = "#finder.code")
public Finder updateFinder(Finder finder, boolean nullValuesAllowed)
{
// gets newFinder that is different
return newFinder;
}
I found the reason why it didn't work. I called this methods from other method in the same class. So this calls didn't get through Proxy object therefore the annotations didn't work.
Correct example:
@Service
@Transactional
public class MyClass {
@CachePut(value = "finders", key = "#finder.code")
public Finder updateFinder(Finder finder, boolean nullValuesAllowed)
{
// gets newFinder
return newFinder;
}
}
and
@Component
public class SomeOtherClass {
@Autowired
private MyClass myClass;
public void updateFinderTest() {
Finder finderWithNewName = new Finder();
finderWithNewName.setCode("abc");
finderWithNewName.setName("123");
myClass.updateFinder(finderWithNewName, false);
}
}
