Mongo - Ignore property from being persisted

问题

I have a standard POJO that has a set of properties in it. The POJO has been annotated as a @Document, so as to be persisted in MongoDB as a Document.

How (annotation??) can I ignore/avoid one of the properties in the POJO from being persisted?

回答1:

The @Transient annotation it is. See http://static.springsource.org/spring-data/data-document/docs/current/reference/html/#mapping-usage-annotations

回答2:

In case you are looking for the actual package like I was, this one will work:

import org.springframework.data.annotation.Transient;

Which is from the Spring framework API documentation.

But this one, which is a JPA annotation, will not work for MongoDB:

import javax.persistence.Transient;

Which is part of the Java Persistence API.

回答3:

use @Transient be aware that you use the below package

import org.springframework.data.annotation.Transient;
