加载log4j配置文件 Log4iConfigurer类

public class Log4iConfigurer {
    
    private static boolean INITIALIZED = false;
    
    public static void initLogger(){
        if(!INITIALIZED&&!isConfigured()){
            InputStream is =Log4iConfigurer.class.getClassLoader().getResourceAsStream("log4j.properties");
            PropertyConfigurator.configure(is);
            IOUtils.closeQuietly(is);
        }
    }

    private static boolean isConfigured() {
        if(LogManager.getRootLogger().getAllAppenders().hasMoreElements()){
            return true;
        }else{
            Enumeration<?> loggers =LogManager.getCurrentLoggers();
            while(loggers.hasMoreElements()){
                Logger logger= (Logger)loggers.nextElement();
                if(logger.getAllAppenders().hasMoreElements()){
                    return true;
                }
            }
        }
        return false;

读取配置文件类Util

    //读取配置文件

打包导出

 　　

另外附上window和linux的启动脚本命令

startup.cmd

echo start elasticsearch-mapping
java -Drunpath=C:Usersll-t150Desktopesmap -Dlog4j.configuration=conf/log4j.properties -cp lib/* com.dinpay.bdp.rcp.service.Start 
pause 

startup.sh

echo start elasticsearch-mapping
java -Drunpath=/home/dinpay/esmap -Dlog4j.configuration=conf/log4j.properties -classpath .:lib/* com.dinpay.bdp.rcp.service.Start
echo "create elasticsearch mapping successfully!"
