javax.persistence.transient和java.bean.transient是否做同样的事情？ [英] Do javax.persistence.transient and java.bean.transient do the same thing?

问题描述

javax.persistence.transient 注释和 java.beans.transient 注释是否做同样的事情？我知道后者仅在Java 7中引入。我只是很好奇，因为我们最近升级到了我们的服务器上的Java 7，我想知道Hibernate是否可以与任一注释一样工作。

解决方案

正如@Wundwin Born之前所说：

javax.persistence.transient将确保Hibernate将忽略该特定字段，将其保存到数据库中，反之亦然。

java.beans.transient将确保特定字段将被编码器忽略（源自编码器）。请参阅 http://docs.oracle.com/javase/ 7 / docs / api / java / beans / Transient.html

Does the javax.persistence.transient annotation and the java.beans.transient annotation do the same thing? I know that the latter was only introduced in Java 7. I'm just curious as we recently upgraded to Java 7 on our servers and I'm wondering if Hibernate will work the same with either of the annotations.

解决方案

As @Wundwin Born said before:

javax.persistence.transient will make sure that Hibernate will ignore that particular field from saving it into the db and vice-versa.

java.beans.transient will make sure that the particular field will be ignored by the encoders (derived from Encoder). See http://docs.oracle.com/javase/7/docs/api/java/beans/Transient.html
