配置hyperjaxb来创建hibernate映射和mysql数据库

本文介绍了配置hyperjaxb来创建hibernate映射和mysql数据库的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我使用hyperjaxb从xsd文件生成Java类。我怎样才能配置它来生成hibernate注释，并触发 hbm2ddl 来为生成的类创建一个包含表的MySQL数据库？

我下载了hibernate的采购订单样本，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，并且这也不包含任何hibernate / MySQL。我想得到一个工作示例，它可以从下载的 xsd 文件创建所有内容，以便我可以插入自己的 xsd 文件放入代码中，并自动生成所有的java / hibernate / mysql。这样我可以花时间调整我的 xsd 文件，以便生成所需的java / hibernate / MySQL。

代码示例或分步说明将非常有帮助。我正在使用eclipse。



**编辑：**



这个问题是在发布了其他一些问题之后发布的要找到这个问题的完整答案，您需要查看其他问题的答案，特别是。

解决方案

UPDATE



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。



所以我希望你能看到，它完美无缺。请发布 mvn clean install -X ，也许你做错了什么。



现在，关于你的问题，这里是MySQL的例子：



这个项目包括一个hbm2ddl代的片段：





hbm2ddl被注释掉了一些理由，不知道它是否有效，但它应该给出方向。


I am using hyperjaxb to generate Java classes from an xsd file. How can I configure it to generate hibernate annotations, and to trigger hbm2ddl to create a MySQL database with tables for the generated classes?

I downloaded the purchase order sample for hibernate from this link, then navigated to the target directory in cmd.exe and ran mvn clean install, but the resulting folders did not contain any java classes, and this also did not contain any hibernate/MySQL. I would like to get a working example that creates everything from a downloaded xsd file so that I can just plug my own xsd file into the code and have all the java/hibernate/mysql be autogenerated. That way I can spend my time tweaking my xsd file so that the resulting java/hibernate/MySQL is what I need it to be.

A code example or step by step instructions would be really helpful. I am using eclipse.

**EDIT: **

The answer to this question came after posting a few other questions. To find the complete answer to this question, you will need to review the answers to those other questions, in particular, the one at this link.

解决方案

UPDATE

Finally it appeared that the OP was looking for generated classes in the root directory of the project insteadof target\generated-source\xjc, despite the tutorial clearly states where to look:

I don't understand it when you say that nothing is generated. I've just rechecked it, everything works fine.

My steps are:

  • Download hyperjaxb3-ejb-samples-po-initial-0.5.6-maven-src.zip
  • Unzip
  • Go to hyperjaxb3-ejb-samples-po-initial-0.5.6
  • mvn clean install

Here's what I get:

Full mvn clean install -X log is here.

So I hope you see, it works perfectly. Please post you mvn clean install -X, maybe you do something wrong.

Now, concerning your question, here's the MySQL example:

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

This project includes a snippet of hbm2ddl generation:

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

The hbm2ddl is commented out for some reason, not sure if it works, but it should give the direction.
