myEclipse 启动监听器报错

郁闷了一上午，运行了myEclipse的clean 后，重新加载我的项目报错了....

从控制台的信息显示
com.ving.xzfw.led.LEDListener
java.lang.NumberFormatException: For input string: ""
得知是读取我的属性文件有错。


com.ving.xzfw.led.LEDListener代码片段

private Timer timer = null;
	private Logger log = Logger.getLogger(getClass());
//	GetconfigInfor config = new GetconfigInfor();
	GetInformation getInfo = new GetInformation("bpelConfig.properties");			
	Integer runTime = Integer.parseInt(getInfo.getProperty("led.TimingRunTime"));	
	String fileRealPath = "";
	String templePath = "";

public void contextInitialized(ServletContextEvent event) {
		// 在这里初始化监听器，在tomcat启动的时候监听器启动，可以在这里实现定时器功能
		ServletContext context = event.getServletContext();

		fileRealPath = context.getRealPath("")
				+ System.getProperty("file.separator") + "LEDFile"
				+ System.getProperty("file.separator");
		templePath = context.getRealPath("")
				+ System.getProperty("file.separator") + "led"
				+ System.getProperty("file.separator");

		timer = new Timer();
		log.info("定时器已启动");// 添加日志，可在tomcat日志中查看到
		timer.schedule(new LEDTimerTack(fileRealPath, templePath), 20000, runTime);
		log.info("已经添加任务");

	}

结合代码可以分析出错代码段

Integer runTime = Integer.parseInt(getInfo.getProperty("led.TimingRunTime"));	

很容易才想到，获取配置属性文件 led.TimingRunTime 为空


那看看配置文件

# checkMachine
#192.168.0.130
#192.168.0.92
sql.dbIP=193.168.92
sql.user=sa
sql.password=1
sql.dbName=zktime65
sql.dbPort=1433

# create LED file
led.ledtemplate=ledtemplate.htm
led.LedRunTime=60000
led.TimingRunTime=500000

配置文件时没有问题的，那怎么会出错了。


再看看控制台的信息：

Can't rea	 from property file: bpelConfig.properties.Make sure that the file is under proper path
Please check the property name 'led.TimingRunTime' and try it again

这里透露很重要的信息：读取属性文件bpelConfig.properties出错了，确保文件路径是否正确....
Ok，let me check and try it again!

呵呵，没有更改任何程序，没有动配置，try ,try ...try several times!
myEclipse 终于肯认错了！哈哈
