web.xml中配置该Filter

1 2 3 4 5 6 7 8

<filter>     <filter-name>post-data-dumper-filter</filter-name>     <filter-class>com.sea.lhsaq2009.PostDataDumperFilter</filter-class> </filter> <filter-mapping>     <filter-name>post-data-dumper-filter</filter-name>     <url-pattern>/*</url-pattern> </filter-mapping>

 

修改tomcat配置文件server.xml

修改 Host标签 下的 value标签

1 2 3

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"          prefix="localhost_access_log." suffix=".txt"          pattern='%h %p %H %l %u %t "%r" params={%{postdata}r} %s %bbytes %Dms' resolveHosts="false"/>
