如何使用实体查询框架对以下查询建模

Question

我们有一个查询，需要检查某个整型字段points是否不为空，以及appointmentDate是否在当前日期之前？如何编写上述场景的约束表达式？

@Entity
public class User {

...
Integer points;
Date appointmentDate;
...
}

Answer 1

如果使用Hibernate

<framework:hibernate-entity-query name="requiredList" scope="conversation" ejbql="from User u where u.appointmentDate < current_date and u.points is not null"/>

如果使用JPA

<framework:entity-query name="requiredList" scope="conversation" ejbql="from User u where u.appointmentDate < current_date and u.points is not null"/>
