java - 配置 hyperjaxb 以创建 hibernate 映射和 mysql 数据库

Question

我正在使用 hyperjaxb 从 xsd 文件生成 Java 类。如何配置它来生成 hibernate 注释，并触发 hbm2ddl 创建一个包含生成类表的 MySQL 数据库？

我下载了 hibernate 的采购订单示例 from this link ，然后导航到 cmd.exe 中的目标目录并运行 mvn clean install，但生成的文件夹不包含任何 java 类，并且也不包含任何 hibernate/MySQL。我想要一个工作示例，它从下载的 xsd 文件创建所有内容，以便我可以将自己的 xsd 文件插入代码中并拥有所有 java/hibernate/mysql 自动生成。这样我就可以花时间调整我的 xsd 文件，以便生成的 java/hibernate/MySQL 正是我需要的。

代码示例或分步说明会非常有帮助。我正在使用 eclipse 。

Answer 1

更新

最后，OP 似乎在项目的根目录中寻找生成的类，而不是 target\generated-source\xjc，尽管 tutorial明确指出要查看的位置:

If you browse the target/generated-sources/xjc directory, you'll find few generated java files, for instance PurchaseOrderType.java.

你说没有生成任何东西，我不明白。我刚刚重新检查了一下，一切正常。

我的步骤是:

• 下载 hyperjaxb3-ejb-samples-po-initial-0.5.6-maven-src.zip
• 解压
• 转到 hyperjaxb3-ejb-samples-po-initial-0.5.6
• mvn 全新安装

这是我得到的:

所以我希望你看到，它工作得很好。请发布您的mvn clean install -X，也许您做错了什么。

现在，关于您的问题，这里是 MySQL 示例:

https://github.com/highsource/hyperjaxb3/tree/master/ejb/tests/po-mysql

该项目包含 hbm2ddl 生成的片段:

https://github.com/highsource/hyperjaxb3/tree/master/ejb/tests/issues

由于某种原因，hbm2ddl 被注释掉了，不确定它是否有效，但它应该给出方向。
