ast.QuerySyntaxException: *** is not mapped

使用eclipse自动生成的DAO文件时，调用dao方法出现以下错误，查资料得到需在实体类前加上包名

错误提示：

Hibernate: select user0_.USER_ID as USER1_1_0_, user0_.EMAIL as EMAIL1_0_, user0_.PASSWORD as PASSWORD1_0_, user0_.SEX as SEX1_0_, user0_.USER_NAME as USER5_1_0_ from bysj.user user0_ where user0_.USER_ID=?

UserDAO.java:125

public List findByProperty(String propertyName, Object value) {
        log.debug("finding User instance with property: " + propertyName
                + ", value: " + value);
        try {
125行→           String queryString = "from User as model where model."
                    + propertyName + "= ?";
            Query queryObject = getCurrentSession().createQuery(queryString);
            queryObject.setParameter(0, value);
            return queryObject.list();
        } catch (RuntimeException re) {
            log.error("find by property name failed", re);
            throw re;
        }
    }

加上包名
String queryString = “from com.bysj.dao.entity.User as model where model.”
修改后如下：


public List findByProperty(String propertyName, Object value) {
log.debug("finding User instance with property: " + propertyName
+ ", value: " + value);
try {
String queryString = "from com.bysj.dao.entity.User as model where model."
+ propertyName + "= ?";
Query queryObject = getCurrentSession().createQuery(queryString);
queryObject.setParameter(0, value);
return queryObject.list();
} catch (RuntimeException re) {
log.error("find by property name failed", re);
throw re;
}
}
