为什么isCaptain即使我将 spring-data 指定为 ，它仍在查看transient？从文档中，transient应该忽略这些属性。如果我使用Boolean包装类没有错误

例外

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "/testContext.xml" })
@Transactional
public class PlayerRepositoryTest

        // either use domain specific method
        Player result = repo.findByPropertyValue("firstName", p.getFirstName());
        assertNotNull("findByPropertyValue should be used for EXACT matches", result);

        // or generic method
        result = repo.findPlayerByFirstName(p.getFirstName());
        assertNotNull("Exact mathch", result);
    }
}

@Transient正如Sotirios Delimanolis作品所建议的那样。我认为该transient关键字不被尊重，因为它可能与需要序列化的用例发生冲突。例如，您可能希望该isCaptain属性在网络会话中可用，但不需要保存到 neo4j，我的确切情况。
