<mapping resource="com/bizengine/km/entity/Articleview1.hbm.xml"></mapping>

Answer 1

这是自动生成的
通过Query qu = session.createQuery("from Articleview1 art");
System.out.println(qu.list().get(0));
打印出是　null
Criteria ctt = session.createCriteria(Articleview1.class);
ArrayList results = (ArrayList) ctt.list();
得到结果也是[]空然后在这里会报错．．
但现在在ECLIPSE里的datebase explorer里对这个视图进行查询没有问题．．．
视图在数据库内也没有部问题．．．
