spring 管理bean，能否new对象
dao层引用了一个对象

public List getRptHead(String rno)throws Exception {

		// TODO Auto-generated method stub

		return TableHeade.getHead(rno);

	}

在这个TableHeade类中有一个静态方法：getHead(rno);
方法

public static List getHead(String rno)

		throws Exception

	{DBManage db = new DBManage();}

当执行getHead(String rno)方法的时候报错

不能new 这个DBManage吗？
不想通过spring来管理DBManage


------解决方案--------------------
不配置就不会管理的，好像错误时没找到类文件哦。
