使用XJC将XML模式转换为java类

Question

我使用的是从这里下载的官方XSD模式：

http://docs.oasis-open.org/ubl/os-UBL-2.0.zip

(路径:xsd/maindoc/UBL Order-2.0.xsd)

当我使用下面的命令用XJC生成java类时，我总是在控制台中得到一个错误，我不知道如何处理这个错误。

命令：

xjc -d C:\Users\Oscar\Desktop\results -p com.ubl.order C:\Users\Oscar\Desktop\os-UBL-2.0\xsd\maindoc\UBL-Order-2.0.xsd

错误：

Failed to produce code.

我尝试的是不使用官方XSD，而是使用trang.jar生成自己的XSD。结果很好，我得到了生成的java类，但是当我使用JAXB (使用这些类)创建XML文档时，名称空间是不正常的。

所以，我想要的是使用非官方的XSD，但是修改(可能)才能使它工作。

如何解决这个问题以获得生成的类？

提前谢谢。

Answer 1

尝尝这个。

确保您的JDK版本是1.6或更高版本，在您的路径环境变量

• $JAVA_HOME/bin环境变量

• 中打开一个cmd并定位到/UBL-2.0/xsd/maindoc

• run：xjc UBL-Order-2.0.xsd

Answer 2

我创建了一个库，它封装了所有的UBL2.0和2.1耗能文件，以及一些与Java1.6和Maven一起使用的明智方法。有关详细信息，请查看https://github.com/phax/ph-ubl。
