为什么我使用SpringCache在Service中有缓存未命中-WhyIhavecachemissesinServiceusingSpringCache

I have configured my cache as follows:

我已按如下方式配置缓存：

@Configuration
@EnableCaching
public class CacheConfig {

    @Bean(name = "caffeineCachingProvider")
    public CachingProvider caffeineCachingProvider() {
        return Caching.getCachingProvider("com.github.benmanes.caffeine.jcache.spi.CaffeineCachingProvider");
    }

    @Bean(name = "caffeineCacheManager")
    public JCacheCacheManager getSpringCacheManager() {
        CacheManager cacheManager = caffeineCachingProvider().getCacheManager();
        CaffeineConfiguration> caffeineCOnfiguration= new CaffeineConfiguration<>();
        caffeineConfiguration.setExpiryPolicyFactory(FactoryBuilder.factoryOf(new AccessedExpiryPolicy(new Duration(TimeUnit.MINUTES, 60))));
        caffeineConfiguration.setCopierFactory(Copier::identity);
        cacheManager.createCache("informerCache", caffeineConfiguration);
        return new JCacheCacheManager(cacheManager);
    }
}

Also I have the @Service that uses it in following way:

我也有@Service以下列方式使用它：

@Service
public class InformerService {

    @CacheResult(cacheName = "informerCache")
    public List getProducts(@CacheKey String category, @CacheKey String countrySign, @CacheKey long townId) throws Exception {
        Thread.sleep(5000);
        // do some work
    }
}

So I have the next behavior.

所以我有下一个行为。

1. When I'm calling the service method first time it takes 5 seconds then doing some work as expected.
2. 当我第一次调用服务方法时需要5秒钟，然后按预期进行一些工作。
3. Calling method the second time with same parameters - > caching works -> returns result immediately
4. 第二次使用相同参数调用方法 - >缓存工作 - >立即返回结果
5. Calling the third time with same parameters again results in Thread.sleep
6. 再次使用相同参数调用第三次会导致Thread.sleep

And all over again.

并且一遍又一遍。

How to solve this ? Is that the issue about proxying ? What did I miss ?

怎么解决这个？这是关于代理的问题吗？我错过了什么 ？
