Tomcat启动报错或警告: org.apache.catalina.webresources.Cache.getResource Unable to add the resource

报错信息如下：**为任意位置

org.apache.catalina.webresources.Cache.getResource Unable to add the resource at [**] to the cache because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

只要在$CATALINA_BASE/conf/context.xml里增加资源最大可缓存的大小就行了，大小可按自己的需要定义

<?xml version='1.0' encoding='utf-8'?><Context>    <WatchedResource>WEB-INF/web.xml</WatchedResource>    <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>    <Resources        cachingAllowed="true"        cacheMaxSize="100000"    /></Context>

更多配置可参考http://tomcat.apache.org/tomcat-8.0-doc/config/resources.html里的详细参数
