Flex里记录日志

在AS里使用方法：
private var logger : ILogger=LoggerManager.getLogger(className);
logger.debug("load Content");

输出结果：
3/23/2009 21:38:18.531 [DEBUG]  IFrame  load Content


组件代码：

import mx.logging.ILogger;
	import mx.logging.Log;
	import mx.logging.LogEventLevel;
	import mx.logging.targets.TraceTarget;
	
	//日志管理 add by fangtengfei
	public class LoggerManager
	{
		private static var logTarget:TraceTarget;
		
		public static function getLogger(className:String):ILogger
		{
			if(logTarget==null)
			{
				// Create a target.
			    logTarget= new TraceTarget();
			    // Log only messages for the classes in the mx.rpc.* and
			    // mx.messaging packages.
			    logTarget.filters=["*"];
			    // Log all log levels.
			    logTarget.level = LogEventLevel.ALL;
			    // Add date, time, category, and log level to the output.
			    logTarget.includeDate = true;
			    logTarget.includeTime = true;
			    logTarget.includeCategory = true;
			    logTarget.includeLevel = true;
			    // Begin logging. 
			    Log.addTarget(logTarget);
			}
			return Log.getLogger(className);
		}

	}

说明：
在Debug模式下打印日志信息。
