1、Spring容器都初始化完成之後做操作

	package com.luwen.dai;

	import org.springframework.beans.factory.annotation.Autowired;
	import org.springframework.context.ApplicationListener;
	import org.springframework.context.event.ContextRefreshedEvent;

	public class ContextFileListener implements ApplicationListener<ContextRefreshedEvent> {

		@Autowired
		private FileMonitor fileMonitor;
		
		@Override
		public void onApplicationEvent(ContextRefreshedEvent event) {
			
				try {
					fileMonitor.monitor();
					fileMonitor.start();
				} catch (Exception e) {
					e.printStackTrace();
				}
		}

	}
