java调试日志封装小工具

主类:

package util;

import java.text.SimpleDateFormat;
import java.util.LinkedList;
import java.util.List;

public class Log {
	private static SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	private static List<Loghandler>loghandlerList;
	private Log() {}
    public static void e(String title,String content) {
    	if(loghandlerList==null)
    		loghandlerList=new LinkedList<Loghandler>();
    	//console输出
    	String out="\n"+title+"-->"+content+"\n TIME:"+getCurrentTIme()+"\n";
    	System.out.print(out);
    	//console输出end
    }
    public static void e_Interface(String title,String content) {
    	content+="\nTIME:"+getCurrentTIme();
    	for(int i=0;i<loghandlerList.size();i++)
    		loghandlerList.get(i).out(title,content);
    }
    public static void attach(Loghandler handler) {
    	if(loghandlerList==null)
    		loghandlerList=new LinkedList<Loghandler>();
    	loghandlerList.add(handler);
    }
    public static void dettach(Loghandler handler) {
    	loghandlerList.remove(handler);
    }
    public static String getCurrentTIme() {
		return df.format(System.currentTimeMillis());
	}
}

辅助接口:

package util;

public interface Loghandler {//消息输出接口
       public void out(String title,String content);
}
