Question

我正在尝试将Grails 1.0.3项目升级到1.3.7，并且我正在考虑相关问题。

旧项目在conf / hibernate / Domain1.hbm.xml中有Hibernate xml文件我猜测1.0.3中不存在GORM？

我是否需要在域/

中的域类中将xml文件中的内容转换为Groovy代码

任何其他细节都有帮助。感谢。

更新 -

所有这些更改都是org.hibernate.DuplicateMappingException的结果。看起来我可以移动域文件：Relevant Post这真的是我想要做的吗？我的理解是，使用GORM我根本不需要使用xml文件。

这是一个例外

GORM肯定存在于Grails 1.0.3中。

您可能只需要更新1.3.7的hibernate配置。看看Grails and Hibernate - Reference Documentation

除非您要映射到旧版或其他不寻常的数据库架构，否则标准GORM域建模是可行的方法。它非常灵活。
