（3） log4j.properties
Log4j.properties，将Log4j的日志输出到 SocketAppender ，因为官网是这么说的E:\u\elk\pic\01_5.png：
Log4j.properties文件：
log4j.rootLogger=INFO,console
# for package com.demo.elk, log would be sent to socket appender.
log4j.logger.com.demo.elk=DEBUG, socket
# appender socket
log4j.appender.socket=org.apache.log4j.net.SocketAppender
log4j.appender.socket.Port=4567
log4j.appender.socket.RemoteHost=192.168.121.62
log4j.appender.socket.layout=org.apache.log4j.PatternLayout
log4j.appender.socket.layout.ConversionPattern=%d [%-5p] [%l] %m%n
log4j.appender.socket.ReconnectionDelay=10000
# appender console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d [%-5p] [%l] %m%n
注意：这里的端口号需要跟Logstash监听的端口号一致，这里是4567。
