解決方案（1 / 2）：
1. 方案1：
我使用的是tomcat7，找到這樣conf 目錄下的catalina.properties文件並打開，找到這行代碼：
org.apache.catalina.startup.ContextConfig.jarsToSkip=
將其改成：org.apache.catalina.startup.ContextConfig.jarsToSkip=*.jar
保存並關閉，重新啟動eclipse和tomcat即可。
2. 方案2：
如果第一種方案不行，那么我們直接將
<absolute-ordering />
這行代碼 放到 項目的 web.xml 即可，加入該代碼后項目可能會標紅，但不影響 項目的運行。
我采用的是方案2
希望對大家有所幫助！~
