@EntityListener 也可以与 @MappedSuperclass 一起使用吗？

Folks!

如果我定义一个实体类并用它注释@MappedSuperclass and an @EntityListener，监听器是否也会被子类中的生命周期事件调用？

Example:

@MappedSuperclass
@EntityListeners(class=LastUpdateListener.class)
public abstract class Animal {
    @Id private Integer id;
    private String name;
    private Calendar dateOfBirth;
    @Transient private int age;
    private Date lastUpdate;
    //getters and setters

    /**
     * Set my transient property at load time based on a calculation,
     * note that a native Hibernate formula mapping is better for this purpose.
     */
    @PostLoad
    public void calculateAge() {
        Calendar birth = new GregorianCalendar();
        birth.setTime(dateOfBirth);
        Calendar now = new GregorianCalendar();
        now.setTime( new Date() );
        int adjust = 0;
        if ( now.get(Calendar.DAY_OF_YEAR) - birth.get(Calendar.DAY_OF_YEAR) < 0) {
            adjust = -1;
        }
        age = now.get(Calendar.YEAR) - birth.get(Calendar.YEAR) + adjust;
    }
}

public class LastUpdateListener {
    /**
     * automatic property set before any database persistence
     */
    @PreUpdate
    @PrePersist
    public void setLastUpdate(Cat o) {
        o.setLastUpdate( new Date() );
    }
}

Thanks.

是的，映射超类中用 @PostLoad 注释的方法和 LastUpdateListener 的实体侦听器方法被调用。

映射超类本身的生命周期事件之类的东西甚至不存在。像往常一样，它适用于子类。
