Question

我编写了一个自定义appender，所以如何在Log4j.xml文件中声明它。

My property file is[custom appender is in org.copofi.common.logging.SystemStatusAppender] :

    log4j.rootLogger=INFO,logfile,console,SystemStatus
    log4j.logger=INFO,logfile,console,SystemStatus

    # Console appender (stdout)
    log4j.appender.console=org.apache.log4j.ConsoleAppender
    log4j.appender.console.layout=org.apache.log4j.PatternLayout
    log4j.appender.console.layout.ConversionPattern=[%d{yy-MM-dd HH:mm:ss.SSS}] [%p] <%t> [%X{jsessionId}] [%c] %m%n

    # File appender
    log4j.appender.logfile=org.apache.log4j.FileAppender
    log4j.appender.logfile.File=${catalina.base}/logs/copofi.log
    log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
    log4j.appender.logfile.layout.ConversionPattern=[%d{yy-MM-dd HH:mm:ss.SSS}] [%p] <%t> [%X{jsessionId}] [%c] %m%n

    log4j.appender.SystemStatus=org.copofi.common.logging.SystemStatusAppender

            <filter class="org.apache.log4j.varia.LevelMatchFilter">
                <!-- only the levels (comma separated) specified in LevelToMatch will be logged -->
                <param name="LevelToMatch" value="DEBUG, WARN,INFO,ERROR, FATAL"/>
                <param name="AcceptOnMatch" value="true"/>
            </filter>
        </appender>

    <root>
        <level value="INFO"/>
        <appender-ref ref="CONSOLE_LOG"/>       
    </root>

</log4j:configuration>
