Log4j远程日志时按业务自定义存放多个文件

在服务器集群中，若是想要集中管理服务器上的日志，能够使用log4j提供的一个远程日志Appender--SocketAppender。且若是须要按不一样的业务，也可自定义存放到不一样的文件中。具体log4j的配置及代码以下：

服务器端：

log4j.properties

log4j.log4j.rootLogger= INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

log4j.logger.myTest1= DEBUG, test1
log4j.appender.test1=org.apache.log4j.FileAppender
log4j.appender.test1.File=D:/log/test1.log
log4j.appender.test1.layout=org.apache.log4j.PatternLayout
log4j.appender.test1.layout.ConversionPattern=%d %p [%c] - %m%n

log4j.logger.myTest2= DEBUG, test2
log4j.appender.test2=org.apache.log4j.FileAppender
log4j.appender.test2.File=D:/log/test2.log
log4j.appender.test2.layout=org.apache.log4j.PatternLayout
log4j.appender.test2.layout.ConversionPattern=%d %p [%c] - %m%n

服务器代码：

package com.yss.demo.log2;

import java.net.InetAddress;

public class Server extends Thread {

	private static final int DEFAULT_PORT = 4560;
	private final int port;

	public Server(int port) {

		this.port = port;
	}

	public Server() {

		this(DEFAULT_PORT);
	}

	@Override
	public final void run() {

		try {
			Logger cat = Logger.getLogger(Server.class);
			cat.info("Listening on port " + port);
			ServerSocket serverSocket = new ServerSocket(port);
			while (true) {
				cat.info("Waiting to accept a new client.");
				Socket socket = serverSocket.accept();
				InetAddress inetAddress = socket.getInetAddress();
				cat.info("Connected to client at " + inetAddress);
				LoggerRepository h = LogManager.getLoggerRepository();
				cat.info("Starting new socket node.");

				// TODO: can we use information in the socket to record the client host?
				new Thread(new SocketNode(socket, h)).start();
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static void main(String[] args) {

		new Server().start();
	}
}

 

客户端：

log4j.properties

log4j.rootLogger=info,socket
log4j.appender.socket=org.apache.log4j.net.SocketAppender
log4j.appender.socket.RemoteHost=localhost
log4j.appender.socket.Port=4560
log4j.appender.socket.LocationInfo=true

客户端代码：

import org.apache.log4j.Logger;

public class Client {

	public static void main(String[] args) throws Exception {

		Logger logger = Logger.getLogger("myTest1");
		logger.info("wwwwwww11111111");
		Logger logger2 = Logger.getLogger("myTest2");
		logger2.info("wwwwwww2222222");
	}
}

 

    log4j默认使用的配置是类路径下的log4j.properties，若是客户端和服务器端代码在同一个项目下时，就须要分别为各自的log4j配置文件从新命名，以示区分，并在获取Logger以前使用
        PropertyConfigurator.configure("Log4JConfig_client.properties");

这种方式加载指定的配置文件，这样才可以使各自的代码、配置生效。
