可以在hazelcast中使用“ cacheResolver”

Question

我正在使用spring缓存和hazelcast，我只是想将响应保存到控制器中：

@Bean
@Override
public CacheManager cacheManager() {
    return new HazelcastCacheManager(hazelcastInstance);
}

//creating hazelcast cache config.
@Bean
public HazelcastClientCacheManager hazelcastClientCacheManager() {
    CachingProvider provider = 
    HazelcastClientCachingProvider.createCachingProvider(hazelcastInstance);
    HazelcastClientCacheManager cacheManager = (HazelcastClientCacheManager) provider.getCacheManager();
    cacheManager.getHazelcastInstance().getConfig().getSerializationConfig().getByteOrder();

    Duration oneHours = Duration.ONE_MINUTE;
    MutableConfiguration<Object, Object> configuration = new MutableConfiguration<>();
    configuration.setTypes(Object.class, Object.class)
        .setExpiryPolicyFactory(AccessedExpiryPolicy.factoryOf(oneHours))
        .setStatisticsEnabled(true);
    cacheManager.createCache("mycache", configuration);*

    return cacheManager;
}

//My CacheResolver 
@Bean
@Override
public CacheResolver cacheResolver() {
    return new CustomCacheResolver(cacheManager());
}

有问题，在我的CacheResolver.class中：

public class CustomCacheResolver implements CacheResolver {
    private final CacheManager cacheManager;

    @Override
    public Collection<? extends Cache> resolveCaches(CacheOperationInvocationContext<?> context) {
        Collection<Cache> caches = new ArrayList<>();
        caches.add(cacheManager.getCache("mycache"));
        return caches;
    }

发件人：

@Cacheable(cacheResolver = "cacheResolver", key = "#uuid+", 
    unless="#result.size() == 0")
myMethod(String uuid){}

问题：CustomCacheResolver中的resolveCaches必须返回缓存集合，但是我在hazelcast中创建的缓存是ICache。

有什么想法吗？我需要使用该缓存及其配置，ttl等。预先谢谢。！

解决方案正在使用：导入com.hazelcast.spring.cache.HazelcastCacheManager

类似这样的东西：

  @Bean
  @Override
  public CacheManager cacheManager() {
    return new HazelcastCacheManager(hazelcastInstance);
  }

  @Bean
  @Override
  public CacheResolver cacheResolver() {
    return new CustomCacheResolver(concurrentMapCacheManager());
  }

  @Bean
  public CacheManager concurrentMapCacheManager() {
    return new ConcurrentMapCacheManager() {
      protected Cache createConcurrentMapCache(final String name) {
          return new ConcurrentMapCache(name,
              CacheBuilder.newBuilder().expireAfterWrite(ttl, TimeUnit.SECONDS).build().asMap(), false);
      }
    };
  }

并创建CustomCacheResolver.class扩展了CacheResolver，就足够了。
