SpringBoot when com.github.ben-manes.caffeine:jcache on classpath, property spring.cache.caffeine.spec didn't work

I add spring-boot-starter-cache and com.github.ben-manes.caffeine:jcache on classpath , also add following properties

spring.cache.type=jcache
spring.cache.caffeine.spec=maximumSize=100,expireAfterWrite=600s
spring.cache.cache-names=projectNodes

but , the property 'spring.cache.caffeine.spec' didn't work, It seems caffeine also need a JCachePropertiesCustomizer when com.github.ben-manes.caffeine:jcache on classpath

Thanks for the report. What's your reason for using Caffeine's JCache Provider in a Spring Boot application? Doing so isn't recommended. As such, I'm not sure that it's something that we'd want to support without good reason.

hibernate‘s second level cache can make use of Jcache, can't directly use caffeineCacheManager or spring's cacheManager

Yes, that is expected. If you opt-in for JCache support rather than the native Caffeine support, you need to configure Caffeine through the JCache APIs. Spring Boot does not have any opinion when you opt-in for JCache as we have to behave how the spec mandates.
