dictHsCode is not mapped

logger：

2016-01-26 11:22:16,812 [http-8080-2] ERROR [org.apache.jsp.WEB_002dINF.jsp.error.exception_jsp] - dictHsCode is not mapped[from dictHsCode t where 1=1 ];

nested exception is org.hibernate.hql.ast.QuerySyntaxException: dictHsCode is not mapped [from dictHsCode t where 1=1 ]

org.springframework.orm.hibernate3.HibernateQueryException: dictHsCode is not mapped [from dictHsCode t where 1=1 ];

nested exception is org.hibernate.hql.ast.QuerySyntaxException: dictHsCode is not mapped [from dictHsCode t where 1=1 ]

    at org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:664)

异常原因：

在xxxDao里写的hql语句的表名要是映射的对应实体类的名称，而不是变量名的名称，也不是数据库里的表名。
