JaxB 重命名具有重复名称的类

问题描述

我必须使用包含以下片段的架构，其中名称 object 重复.

I have to use a schema which contains the following snippet where the name object is duplicated.

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:complexType name="param_object_type">
        <xs:sequence>
            <xs:element name="object" minOccurs="0" maxOccurs="unbounded">
            <xs:complexType>
                <xs:sequence>
                    <xs:element name="object" minOccurs="0" maxOccurs="unbounded">
                </xs:sequence>
            </xs:complexType>
        </xs:sequence>
    </xs:complexType>

</xs:schema>

Jaxb 最初很乐意导入它，但由于 Object 类被声明了两次，因此无法编译源代码.

Jaxb was originally happy to import this, but would fail to compile the sources since the Object class was declared twice.

我添加了 globalBindings 选项 localScoping="toplevel" 现在这会导致以下编译时错误:

I added globalBindings option localScoping="toplevel" and this now leads to the following compile time error:

org.xml.sax.SAXParseException;systemId:具有相同名称jaxb.Object"的类/接口已在使用中.使用类自定义来解决此冲突.

所以我尝试添加自定义绑定来重命名对象之一，jaxb:class 和 jaxb:property.两者都产生相同的错误.

So I tried adding a custom binding to rename one of the objects, jaxb:class and jaxb:property. Both produce the same error.

如果有帮助，这是我的绑定文件:

If it helps, here is my bindings file:

<jaxb:bindings version="2.0" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <jaxb:bindings>
        <jaxb:globalBindings generateElementProperty="false" fixedAttributeAsConstantProperty="true" choiceContentProperty="true" localScoping="toplevel"/>
    </jaxb:bindings>
    <jaxb:bindings  schemaLocation="../xsd/NodeSchema.xsd" node="/xs:schema">
        <jaxb:bindings node="/xs:schema/xs:complexType[@name='param_object_type']/xs:sequence/xs:element[@name='object']">
            <jaxb:class name="object2"/>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>

如何确保其中一个实例被重命名而另一个保持不变?

How can I make sure that one of these instances gets renamed and the other is left intact?

正确的复杂类型.. xs:element

XSD

<xs:complexType name="param_object_type">
    <xs:sequence>
        <xs:element name="object" minOccurs="0" maxOccurs="unbounded">
            <xs:complexType>
                <xs:sequence>
                    <xs:element name="object" minOccurs="0" maxOccurs="unbounded" />
                </xs:sequence>
            </xs:complexType>
        </xs:element>
    </xs:sequence>
</xs:complexType>

绑定

<jxb:bindings node="//xs:schema//xs:complexType[@name='param_object_type']//xs:sequence//xs:element[@name='object']//xs:complexType//xs:sequence//xs:element[@name='object']">
    <jxb:class name="object2" />
