Grails 1.0.3 升级问题 [英] Grails 1.0.3 Upgrade Problems

问题描述

我正在尝试将 Grails 1.0.3 项目升级到 1.3.7，并且遇到了我认为相关的问题.

I am trying to upgrade a Grails 1.0.3 project to 1.3.7 and am having what I believe are related issues.

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

The old project has Hibernate xml files in conf/hibernate/Domain1.hbm.xml I am guessing that GORM didn't exist in 1.0.3?

我是否需要将 xml 文件中的内容本质上转换为域中的域类中的 Groovy 代码/

Do I need to essentially convert what is in the xml files into Groovy code in the Domain classes in domain/

任何其他细节都有帮助.谢谢.

Any other details are helpful. Thanks.

更新-

所有这些更改都是 org.hibernate.DuplicateMappingException 的结果，看起来我只能移动域文件:相关帖子 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.

All of these changes are the result of a org.hibernate.DuplicateMappingException It looks like I can just move the domain files: Relevant Post Is that really what I want to do though? My understanding is that with GORM I wouldn't need to use the xml files at all.

这里有一个例外

推荐答案

Grails 1.0.3 中肯定存在 GORM.

GORM certainly existed in Grails 1.0.3.

您可能只需要更新 1.3.7 的休眠配置.看看 Grails 和 Hibernate - 参考文档

You'll probably just have to update your hibernate configuration for 1.3.7. Take a look at the Grails and Hibernate - Reference Documentation

除非您要映射到遗留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.

Unless you are mapping to a legacy or otherwise unusual database schema the standard GORM domain modelling is the way to go. It's very flexible.
