java - 可以在 Scala 中使用 Spring 缓存

Question

嗨，我想知道是否可以在 Scala 中利用 Spring 带注释的缓存。我已经尝试过，但收到以下错误。我正在从依赖于 scala 包的 java 包运行应用程序。

 No cache could be resolved for 'CacheableOperation[public scala.collection.immutable.List MerchantDataGateway.getAllMerchants()]

我的配置类

@Configuration
@EnableCaching
@ComponentScan(basePackages = "xxx.xxx.xxx.xxx")
public class EnvironmentHelperConfig {

    @Bean
    public CacheManager getCacheManager() {
        final int ttl = 12;
        final int maxCacheSize = 1012;

        GuavaCacheManager result = new GuavaCacheManager();
        result.setCacheBuilder(CacheBuilder
                .newBuilder()
                .expireAfterWrite(ttl, TimeUnit.HOURS)
                .maximumSize(maxCacheSize));

        return result;
    }
}

我的 Scala 类

@Component
class MerchantDataGateway {

  @Autowired
  var fmcsProxy: MerchantResource = null;

  @Cacheable
  def getAllMerchants(): List[MerchantViewModel] = {
    val merchants = getAllMerchantsFromFMCS()
    merchants.map(merchant => MerchantViewModel.getLightWeightInstance(merchant))
  }
}

Answer 1

为@Cacheable注解添加一个名称:

@Cacheable(Array("MerchantDataGateway.getAllMerchants"))
