Spring Cloud LoadBalancer's cache won't show in /actuator/caches

[eacdy]

As the title. I use Spring Cloud LoadBalancer, but When I call /actuator/caches , It just shows json like below:

{
    "cacheManagers": {}
}

I think It Should show Spring Cloud LoadBalancer's cacheManager.

I don't know. That is specifically for the cache managers provided by spring framework. As such, it may not be possible to plug in custom cache managers. /cc @wilkinsona @philwebb?

Assuming that the load balancer's cache manager is a org.springframework.cache.CacheManager and that it is exposed as a bean in the application context, it should be picked up by the caches endpoint.

This was done very specifically as to not interfere with the user-defined cache manager. Unless we can come up with a simple way to have the cache manager not over-ride the user configured one, we may have to live without the cache manager showing up in the actuator.

You could experiment with that idea without any changes in Boot using a BeanFactoryPostProcessor that calls setPrimary on the cache manager’s bean definition
