liferay6.1 启用logj4j.properties定义日志

在编译好的环境下 即tomcat/webapp/ROOT/WEB-INF/classes中加入system-ext.properties

其内容如下：

##
## Logging
##

    #
    # Set any logger that implements org.apache.commons.logging.Log.
    #
    org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger

    #
    # Set this to true if Log4j complains that it was not properly configured.
    #
    log4j.configure.on.startup=false

 

再在该目录下加入自己定义的log4j.properties 即可
