5. 缓存随机属性源

Spring Cloud Context 提供了一个PropertySource基于键缓存随机值。缓存之外它的工作原理与 Spring Boot 的RandomValuePropertySource. 如果想要一个即使在 Spring 应用程序之后也保持一致的随机值，则此随机值可能很有用上下文重新启动。属性值采用cachedrandom.[yourkey].[type]哪里yourkey是缓存中的键。这type值可以是 Spring Boot 支持的任何类型RandomValuePropertySource.spring-doc.cadn.net.cn

myrandom=${cachedrandom.appname.value}
