Java自定义记录器:日志记录标准或最佳实践

我正在开发一个框架,我不会让jar变得更轻,更独立。

所以我写了我的日志类:

import java.util.Date;
import java.util.Properties;

public class Logger {

    private static final Logger me = new Logger();

    private static boolean info = false;
    private static boolean debug = false;
    private static boolean error = false;

    private static String className = null;

    public static Logger getInstance(Class<?> clazz) {  
        className = clazz.getCanonicalName();
        try {
            Properties props = new CustProps().load(clazz);
            if(props.get(CustProps.NAME_LOG_MODE) != null) {
                String devMode = props.getProperty(CustProps.NAME_LOG_MODE).toLowerCase();
                if("info".equals(devMode)) {
                    info = true;
                    debug = true;
                } else if("debug".equals(devMode)) {
                    debug = true;
                } 
            }
        } catch (Exception e) {
            // debug is error by default
        }

        error = true;

        return me;
    }

    public void logError(Object msg) {
        if(isError()) {
            System.out.println(new Date().toString()+ " ERROR ["+Logger.className+"] - " + msg);
        }
    }

    public void logDebug(Object msg) {
        if(isDebug()) {
            System.out.println(new Date().toString()+ " DEBUG ["+Logger.className+"] - " + msg);
        }
    }

    public void logInfo(Object msg) {
        if(isInfo()) {
            System.out.println(new Date().toString()+ " INFO ["+Logger.className+"] - " + msg);
        }
    }


    public boolean isInfo() {
        return Logger.info;
    }

    public boolean isDebug() {
        return Logger.debug;
    }

    public boolean isError() {
        return Logger.error;
    }
}

什么是使日志记录更好的最佳实践? 让你自己的伐木工人更值得吗? 使用这个记录器会使我的框架比选择现有的东西(如log4j)更糟糕吗?
