以下字段在用于JMX的Spring @ManagedResource中意味着什么？ Spring documentation中没有Javadoc或相关描述。
1.字符串persistPolicy()默认为“”；
2. intpersistPeriod()默认为-1；
3.字符串persistLocation()默认为“”；
4. int currencyTimeLimit()默认为-1；
最佳答案
这些被传递到JMX api上-您可以在JMX java doc中找到有关它的更多信息。在此处复制相关部分-
persistPolicy : OnUpdate|OnTimer|NoMoreOftenThan|OnUnregister|Always|Never
persistLocation : The fully qualified directory name where the MBean should be persisted (if appropriate)
persistFile : File name into which the MBean should be persisted
persistPeriod : seconds - frequency of persist cycle for OnTime and NoMoreOftenThan PersistPolicy
currencyTimeLimit : how long value is valid, <0 never, =0 always, >0 seconds
