Spring Cache @Cacheable - not working while calling from another method of the same bean

Question

Spring cache is not working when calling cached method from another method of the same bean.

Here is an example to explain my problem in clear way.<

Answer 1

I use internal inner bean (FactoryInternalCache) with real cache for this purpose:

@Component
public class CacheableClientFactoryImpl implements ClientFactory {

private final FactoryInternalCache factoryInternalCache;

@Autowired
public CacheableClientFactoryImpl(@Nonnull FactoryInternalCache factoryInternalCache) {
    this.factoryInternalCache = factoryInternalCache;
}

/**
 * Returns cached client instance from cache.
 */
@Override
public Client createClient(@Nonnull AggregatedConfig aggregateConfig) {
    return factoryInternalCache.createClient(aggregateConfig.getClientConfig());
}

/**
 * Returns cached client instance from cache.
 */
@Override
public Client createClient(@Nonnull ClientConfig clientConfig) {
    return factoryInternalCache.createClient(clientConfig);
}

/**
 * Spring caching feature works over AOP proxies, thus internal calls to cached methods don't work. That's why
 * this internal bean is created: it "proxifies" overloaded {@code #createClient(...)} methods
 * to real AOP proxified cacheable bean method {@link #createClient}.
 *
 * @see Spring Cache @Cacheable - not working while calling from another method of the same bean
 * @see Spring cache @Cacheable method ignored when called from within the same class
 */
@EnableCaching
@CacheConfig(cacheNames = "ClientFactoryCache")
static class FactoryInternalCache {

    @Cacheable(sync = true)
    public Client createClient(@Nonnull ClientConfig clientConfig) {
        return ClientCreationUtils.createClient(clientConfig);
    }
}
}
