从 XSD 模式生成 Java 类

Question

我正在尝试从 XSD 架构 http://docs.oasis-open.org/ws-sx/ws-trust/200512/ws-trust-1.3.xsd 生成 java 类。

为此，我使用 jaxb2-maven-plugin 和 xjc 来生成这些眼镜。但是运行进入以下错误

http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd [87,40]
org.xml.sax.SAXParseException; systemId: http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd; lineNumber: 87; columnNumber: 40; A class/interface with the same name "com.abccompany.wstrust.ReferenceType" is already in use. Use a class customization to resolve this conflict.

所以我尝试使用绑定来解决冲突，这样

<jxb:bindings version="1.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xsd="http://www.w3.org/2001/XMLSchema" schemaLocation="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" >
    <jxb:bindings node="//xsd:complexType[@name='ReferenceType']">
        <jxb:class name="AbstractReferenceType1" />
    </jxb:bindings>
</jxb:bindings>

但我仍然遇到以下错误

[ERROR] http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd [152,58]
com.sun.istack.SAXParseException2; systemId: http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd; lineNumber: 152; columnNumber: 58; Two declarations cause a collision in the ObjectFactory class

试图为 xmldsig-core-schema.xsd 架构添加绑定，但它不起作用。你如何准确地找出错误中提到的这个行号和列号？如果我只是在记事本中复制架构，则该行号会出现在不相关的 xml 标记中。

有没有人试过生成这些类？

正如@KarlNicholas 所建议的，我运行 xjc 没有任何其他选项，它为我生成了类。每次，我将 -p 作为选项传递，它都会抛出我发布的错误。
