使用 SDK > 3.0 进行缓存 - 未配置 CachingProvider
Caching with SDK > 3.0 - No CachingProviders have been configured
我正在尝试使用 java SDK 版本 3.9.0 进行一些缓存后端调用。我找到的关于 SDK 版本 > 3.0.0 的缓存的唯一资源是官方发行说明和 this 9 月份社区更新回调的回放视频。
在或多或少地从视频中复制代码并根据我的目的对其进行调整后，我想出了以下方法来尝试缓存自己：
private final ResilienceConfiguration configuration;
private final String purchaseOrder;
public GetSupplierFromPOCommand(String purchaseOrder) {
this.purchaseOrder = purchaseOrder;
this.configuration = ResilienceConfiguration.of(GetSupplierFromPOCommand.class)
.cacheConfiguration(ResilienceConfiguration.CacheConfiguration.of(Duration.ofHours(1)).withParameters(purchaseOrder));
}
public PurchaseOrder execute() {
logger.info("Running " + this.getClass().getName() + " ...");
Callable<PurchaseOrder> poCallable = ResilienceDecorator.decorateCallable(this::run, configuration);
try {
return poCallable.call();
} catch (Exception e) {
throw new RuntimeException("Failed to retrieve purchase order", e);
}
}
private PurchaseOrder run() throws ODataException {
Destination destination = DestinationAccessor.getDestination(DESTINATION_NAME);
return new DefaultPurchaseOrderService()
.getPurchaseOrderByKey(purchaseOrder)
.select(PurchaseOrder.SUPPLIER)
.execute(destination.asHttp());
}
但是，当我尝试 运行 此命令时，出现以下异常 javax.cache.CacheException: No CachingProviders have been configured。正如发行说明所建议的那样，我将咖啡因作为 JCache 实现添加为我的应用程序 pom 的依赖项，但错误仍然存在。
问题是，我做错了什么？感谢任何帮助。
