Question

我正在使用部署在Tomcat 7环境中的复制ehcache。这里发生的事情是tomcat需要很长时间才能启动，日志中充满了ehcache心跳消息。

关于如何加速ehcache和Tomcat启动的任何想法？

我的ehcache.xml -

您需要将引导程序策略更改为异步（bootstrapAsynchronously=true）以避免启动时出现延迟，即：

<bootstrapCacheLoaderFactory
        class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"
        properties="bootstrapAsynchronously=true, maximumChunkSizeBytes=5000000"
        propertySeparator="," />

Ehcache集群需要很长时间才能在Tomcat上启动
