1.服务端配置

1)服务端配置文件log4j-server.properties

#Define a narrow log category. A category like debug will produce some extra logs also from server itselflog4j.rootLogger=ERROR, file#Define how the socket server should store the log eventslog4j.appender.file=org.apache.log4j.RollingFileAppenderlog4j.appender.file.File=application-error.loglog4j.appender.file.MaxFileSize=1MBlog4j.appender.file.MaxBackupIndex=1log4j.appender.file.layout=org.apache.log4j.PatternLayoutlog4j.appender.file.layout.ConversionPattern=[%d] [%t] [%m]%n

2)服务端启动监听

java -classpath c:/log4j-1.2.17.jar     org.apache.log4j.net.SimpleSocketServer4712 c:/log4j-server.properties

注意，log4j-1.2.17.jar和配置文件都放在C盘，具体指定好位置即可，4712是监听的端口号。

2.客户端配置

1)客户端配置文件log4j.properties

#Define the log4j configuration for local applicationlog4j.rootLogger=ERROR, server#We will use socket appenderlog4j.appender.server=org.apache.log4j.net.SocketAppender#Port where socket server will be listening for the log eventslog4j.appender.server.Port=4712#Host name or IP address of socket serverlog4j.appender.server.RemoteHost=localhost#Define any connection delay before attempting to reconnectlog4j.appender.server.ReconnectionDelay=10000

2)代码中使用

private static final Logger logger = LoggerFactory.getLogger(xx.class);logger.error("test name:{}",guolei);

3.其他注意点

由于我们在项目中并不是要将所有的日志全部发送到远程服务器，而只是发送部分类中的，需要做特殊配置。如下：

log4j.logger.com.wanmei.marketing.RuleShowAction=INFO,server
