log4j中将日志发送到远程服务器

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 itself
log4j.rootLogger=ERROR, file

#Define how the socket server should store the log events
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=application-error.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[%d] [%t] [%m]%n

java -classpath c:\log4j-1.2.17.jar     org.apache.log4j.net.SimpleSocketServer
4712 c:\log4j-server.properties

2.客户端配置

1)客户端配置文件log4j.properties

#Define the log4j configuration for local application
log4j.rootLogger=ERROR, server

#We will use socket appender
log4j.appender.server=org.apache.log4j.net.SocketAppender

#Port where socket server will be listening for the log events
log4j.appender.server.Port=4712

#Host name or IP address of socket server
log4j.appender.server.RemoteHost=localhost

#Define any connection delay before attempting to reconnect
log4j.appender.server.ReconnectionDelay=10000

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
