Spring Boot 2执行器指标缓存

Question

我有一些储藏室

@Service
@CacheConfig(cacheNames = "myCache")
public class MyService { ... }

@Service
@CacheConfig(cacheNames = "myOtherCache")
public class MyOtherService { ... }

I get with“/执行器/指标/缓存。get”

{
  "name" : "cache.gets",
  "measurements" : [ {
    "statistic" : "COUNT",
    "value" : 5.0
  } ],
  "availableTags" : [ {
    "tag" : "result",
    "values" : [ "hit", "miss" ]
  }, {
    "tag" : "cache",
    "values" : [ "myCache", "myOtherCache" ]
  }, {
    "tag" : "name",
    "values" : [ "myCache", "myOtherCache" ]
  }, {
    "tag" : "cacheManager",
    "values" : [ "cacheManager" ]
  } ]
}

如何获取myCache和myOtherCache的命中和未命中值？
