1.在spring中启动线程
		Thread thread = new Thread(new AutoRun ());
		thread.start();

2.线程类中用到了spring进行DI注入 sqlService

public class AutoRun implements Runnable {
	
	@Resource
	private SqlService sqlService;

	public void setSqlService(SqlService sqlService) {
		this.sqlService = sqlService;
	}

	public void run() {
		while (true) {
			try {
				
				String a = new Date().toLocaleString();			
				sqlService.read("select '"+a+"' from dual");
				
				System.out.println(a);

				Thread.sleep(100);// 休眠2分钟

			} catch (InterruptedException e) {
				e.printStackTrace();
			} catch (Exception e) {
				e.printStackTrace();
			}

		}
	}
}

3.会报空指针错误，

4.只能通过该类的构造函数从调用类中传过来，或者

//得到容器
ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
//使用容器调用bean
RagBady bady=(RagBady)context.getBean("rag");
