== CachedRandomPropertySource
Spring Cloud Context provides a `PropertySource` that caches random values based on a key. Outside of the caching
functionality it works the same as Spring Boot's https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot/src/main/java/org/springframework/boot/env/RandomValuePropertySource.java[`RandomValuePropertySource`].
This random value might be useful in the case where you want a random value that is consistent even after the Spring Application
context restarts. The property value takes the form of `cachedrandom.[yourkey].[type]` where `yourkey` is the key in the cache. The `type` value can
be any type supported by Spring Boot's `RandomValuePropertySource`.
