tomcat下单独设置某个app的access log

在project的META-INF目录下添加context.xml文件, 内容:
<Context> <WatchedResource>WEB-INF/web.xml</WatchedResource> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="appname_localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false" buffered="false"/> </Context>
这样就能够单独设置某个app的access log了

如果把这一段放到server.xml中, 那么就是记录所有app的access log:
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="appname_localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false" buffered="false"/>
