Springmvc+mybatis tomcat启动完成操作数据库

[qq_24297221]

public class Tggg  implements ServletContextListener{
	@Autowired
	public UserOperation userOperation;
	public Tggg() {
		System.out.println(userOperation); //null
		
	}
	@Override
	public void contextDestroyed(ServletContextEvent arg0) {
		// TODO Auto-generated method stub
	}
	@Override
	public void contextInitialized(ServletContextEvent arg0) {
		// TODO Auto-generated method stub
		System.out.println(userOperation); //null
	}
}

在web.xml中加监听，监听到后获取不到数据源
怎么才能拿到连接查数据库

你发的代码根本看不出来什么问题啊
