安装文档配置好JFinal-event不执行，求解？?报错

我在用户登录后需要记录一下登录日志，安装JFinal-event的文档分别写好了LoginLogEvent及LoginLogListener类，但是在系统启动的时候，控制台会显示Listener is empty! Please check it!，然后事件并没有执行。

报错信息：

六月 06, 2016 1:26:10 下午 net.dreamlu.utils.ClassUtil warn
警告: Listener is empty! Please check it!

警告: Listener is empty! Please check @Listener is right?

//添加事件触发插件
		EventPlugin eventPlugin = new EventPlugin();
		//开启全局异步
		eventPlugin.async();
		//设置扫描jar包
		eventPlugin.scanJar();
		//设置监听器默认包
		eventPlugin.scanPackage("com.apos");
		me.add(eventPlugin);

代码如下：

@Listener(order=1,enableAsync=true)
public class LoginLogListener implements ApplicationListener<LoginLogEvent> {

	@Override
	public void onApplicationEvent(LoginLogEvent event) {
		// TODO Auto-generated method stub
		UserInfo user=(UserInfo) event.getSource();
		UserLoginLog loginLog = new UserLoginLog();
		loginLog.setUid(user.getUid());
		loginLog.setStoreCode(user.getStoreCode());
		loginLog.set("loginDateTime", DateTools.getNowDateTime());
		loginLog.save();
		System.out.println(Thread.currentThread().getName()+"\tsource:"+event.getSource());
	}

}

public class LoginLogEvent extends ApplicationEvent {

	public LoginLogEvent(Object source) {
		super(source);
		// TODO Auto-generated constructor stub
	}
