Shutting Down Ehcache Properly

· Java Zone

Discover how AppDynamics steps in to upgrade your performance game and prevent your enterprise from these top 10 Java performance problems, brought to you in partnership with AppDynamics.

If you’re using ehcache’s disk persistence feature, which allows the cache to survive across JVM restarts, be sure to shut down ehcache properly.

To do so when using ehcache within a webapp, simply add its ShutdownListener as a listener in web.xml.

<listener>
<listener-class>net.sf.ehcache.constructs.web.ShutdownListener</listener-class>
</listener>

Alternatively, or when not using ehcache inside a webapp, instruct ehcache to register its own shutdown hook by setting a system property.

net.sf.ehcache.enableShutdownHook=true

If you forget one of the above, your persisted cache may not be up-to-date, or worse, not persisted at all.
