Tomcat8 启动过程中提示：

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

解决办法：

在 /conf/context.xml 的 </Context>前添加以下内容：

<Resources cachingAllowed="true" cacheMaxSize="100000" />
