Tomcat8 啟動過程中提示：
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
解決辦法：
在 /conf/context.xml 的 </Context>前添加以下內容：
<Resources cachingAllowed="true" cacheMaxSize="100000" />
