编写WSDL绑定

Question

我使用WSDL来生成Java类，以访问Zuora SOAP API。

不幸的是，这个WSDL有冲突: Maven CXF插件抛出一个错误，并显示“两个声明导致ObjectFactory类中的冲突”的消息。

冲突发生在Invoice.PaymentAmount和Payment.Amount之间

<definitions xmlns="http://schemas.xmlsoap.org/wsdl/" 
    xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
    xmlns:zns="http://api.zuora.com/" 
    xmlns:ons="http://object.api.zuora.com/"
    xmlns:fns="http://fault.api.zuora.com/"
    targetNamespace="http://api.zuora.com/">
    <types>
        <schema attributeFormDefault="qualified" elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://object.api.zuora.com/">
            <import namespace="http://api.zuora.com/" />
            <complexType name="zObject">
                <sequence>
                    <element minOccurs="0" maxOccurs="unbounded" name="fieldsToNull" nillable="true" type="string" />
                    <element minOccurs="0" maxOccurs="1" name="Id" nillable="true" type="zns:ID" />
                </sequence>
            </complexType>

            <complexType name="Invoice" >
                <complexContent>
                    <extension base="ons:zObject">
                        <sequence>
                            <element minOccurs="0" name="AccountId" nillable="true" type="zns:ID" />
                            <element minOccurs="0" name="AdjustmentAmount" nillable="true" type="decimal" />
                            <element minOccurs="0" name="PaymentAmount" nillable="true" type="decimal" />
                            <!--more elements-->
                        </sequence>
                    </extension>
                </complexContent>
            </complexType>

            <complexType name="Payment" >
                <complexContent>
                    <extension base="ons:zObject">
                        <sequence>
                            <element minOccurs="0" name="AccountId" nillable="true" type="zns:ID" />
                            <element minOccurs="0" name="AccountingCode" nillable="true" type="string"  />
                            <element minOccurs="0" name="Amount" nillable="true" type="decimal" />
                            <!--more elements-->
                        </sequence>
                    </extension>
                </complexContent>
            </complexType>

            <!--more types-->

正如这篇文章所建议的，诀窍似乎是一个外部绑定文件。https://community.zuora.com/t5/API/quot-Two-declarations-cause-a-collision-in-the-ObjectFactory/td-p/11265

但是没有代码示例；而且我不知道如何编写这样的绑定文件。

我试过了：

<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           version="1.0">
    <jaxb:bindings schemaLocation="zuora.a.77.0.wsdl">
        <jaxb:bindings node="//xs:element[@name='PaymentAmount']/xs:complexType">
            <jaxb:factoryMethod name="PaymentAmout2"/>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>

但它似乎过于简单，并抛出了一个

"file:/home/kemkem/Work/repo/asap/tooling-zuora/src/main/resources
/wsdl/zuora.a.77.0.wsdl" is not a part of this compilation. 
Is this a mistake for "file:/home/kemkem/Work/repo/asap/tooling-zuora/
src/main/resources/wsdl/zuora.a.77.0.wsdl#types1"

有没有更好的方法来解决这个问题？

似乎可以与以下设置一起工作

src/resources/ wsdl /zuora.a.77.0.wsdl中的wsdl文件

src/resources/binding.xml：

<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
               xmlns:xs="http://www.w3.org/2001/XMLSchema"
               version="1.0">
    <jaxb:bindings schemaLocation="wsdl/zuora.a.77.0.wsdl#types1">
        <jaxb:bindings node="//xs:element[@name='PaymentAmount']">
            <jaxb:factoryMethod name="PaymentAmout2"/>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>

Maven CXF插件：
