          *    问题： home402 is not mapped [from home402];
          *    最后发现了问题所在，hql查询时使用的from Xxx，Xxx不是实体类的名称，而是 EntityName （Hibernate注解）。
                如：
                
                @Entity
                @Table(name="QING_AO_CENTER_INFO")
                public class QingAoCenterInfo {
                         ......
                }
                此处，
                
                @Entity后并没有显示的指明EntityName，因此默认采用实体类的名称。
                
                @Entity(name="QING_AO_CENTER_INFO")
                @Table(name="QING_AO_CENTER_INFO")
                public class QingAoCenterInfo {
                             ......
                }
                可以发现，显示地指明了 EntityName，因此在使用hql查询的时候，要from   QING_AO_CENTER_INFO，而不是from  QingAoCenterInfo ；
                
                centerList = manager.find("from QING_AO_CENTER_INFO center where center.type = ? and center.centerName = ?", new Object[]{type,centerName});
