从XSD问题生成JAXB类

Question

我有一堆XSD文件，并将它们添加到我的项目中，以使用JAXB从它们生成类。 我正在使用JDeveloper 11，JDK 1.6和JAXB 2.0。 XSD文件会导入其他XSD文件，因此我正在生成主文件的内容模型，但是，我一直收到此错误An error was encountered while migrating JAXB. Property "Any" is already defined. Use <jaxb:property> to resolve this conflict. An error was encountered while migrating JAXB. Property "Any" is already defined. Use <jaxb:property> to resolve this conflict.

文件的其余部分可能包含相同名称的类型。

我还尝试注释掉选择项内的所有xs:any元素，只留下一个，还注释掉了它们相应的导入，并且能够生成jaxb类。 但是，如果我再添加一个，则会收到错误消息。

我使用JDeveloper 12c和Eclipse尝试了同样的事情，但是发生了同样的事情。

这可能是问题所在，我也尝试查找问题，但没有找到任何对我有用的方法。

以下是主要的XSD文件

此错误告诉您需要使用JAXB绑定文件来修改要与默认值“ Any”的每个xs：any行关联的集合名称。

我在Oracle网站上找到了一些文档，网址为https://docs.oracle.com/cd/E17802_01/webservices/webservices/docs/1.5/tutorial/doc/JAXBUsing4.html

我还发现这个相关的stackoverflow答案应该是有用的（它具有定义了jaxb：property元素的完整绑定文件的示例）： https ://stackoverflow.com/a/4394185/265237

编写绑定文件后，需要将其与XSD一起传递给XJC，此文件的命令行版本为：

xjc schema.xsd -b bindings.xjb
