spring 取数据后用关闭SESSIOn吗？

ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
MenuListDAO obj = (.MenuListDAO)ctx.getBean("MenuListDAO");
List<MenuList > result=obj.byWhere("1=1") ;
        for(MenuList  o:result)
        {
            System.out.println("姓名："+o.getMenuName() );
        }
这样取数据后用关闭SESSIOn吗？如 hebinate 要这样写 session.close()  spring怎么写？
