org.hibernate.hql.ast.QuerySyntaxException: p_user is not 地图ped [from p_user]

org.hibernate.hql.ast.QuerySyntaxException: p_user is not mapped [from p_user]

org.hibernate.hql.ast.QuerySyntaxException:?p_user is not mapped [from?p_user]

实体类用的注解：

@Entity

@Table(name = "p_user")

public class User {

...........

}

报这个错，搞了半天才能明白，这是HQL查询，面向对象，跟SQL不一样，所以在写HQL语句时，要写成from User。
