"client not initialized" 将 SSMCache 与 AWS elasticache 自动发现结合使用时出错

Question

我正在将 Spring 缓存与 AWS elasticache 提供程序一起使用。我收到此警告：

WARN c.g.code.ssm.spring.SSMCache - An error has occurred for cache defaultCache and key 

java.lang.IllegalStateException: Client is not initialized

    at com.google.code.ssm.spring.SSMCache.get(SSMCache.java:100) [spring-cache.jar:na]

我正在使用没有 spring 缓存的相同内存缓存，它工作正常。仅当我使用 spring 缓存时才会出现此错误。

我已验证安全组指定了入站端口，我是运行我在 EC2 上的代码。

添加我的配置 -

显示您的配置和使用情况。

看来您没有定义 defaultCache 或在没有设置 'value' 参数的情况下使用 Cacheable。
