tomcat日志警告WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'debug' to '0' did not find a matching property.

日志中有警告: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'debug' to '0' did not find a matching property.

跟踪后发现是连接池的配置问题：

<Context path="/n" docBase="E:/xxx/war" debug="0" reloadable="true" crossContext="false">

把debug="0"去除即可。

具体原因未查。
