我在将JAXB模型树编组到xml文件时遇到了问题.

我使用xjc创建了这些模型类.我无法修改这些xml架构 - 它们是在外部定义的(类似于缺少答案的这个问题).

根据xjc(和其他xml工具),xml架构文件似乎是有效的.我在问是否

• 这是一个java/jre bug 或
• 我做错了什么 或者
• 如果架构文件有点错误

以及如何解决此问题.

我得到的例外是:

com.sun.istack.internal.SAXException2: "com.mypackage.A" is substituting "com.mypackage.BaseType", but "com.mypackage.A" is bound to an anonymous type.

我正在从1.x版升级项目到jaxb 2.2.7.

我的应用程序有时会工作,但在一些回复中我看到了这个:

java.lang.RuntimeException: javax.xml.bind.MarshalException
- with linked exception:
[com.sun.istack.SAXException2: Instance of "com.mycompany.global.er.decoupling.binding.response.PricePointType$BalanceImpactRates$BalanceImpactRate" 
is substituting "java.lang.Object", but 
"com.mycompany.global.er.decoupling.binding.response.PricePointType$BalanceImpactRates$BalanceImpactRate"
 is bound to an anonymous type.]

这在jaxb 1.0中运行良好.我不知道问题是什么.

这是xsd的摘录(我无法更改,因为客户端正在使用它):

<xs:complexType name="price-pointType">
    <xs:sequence>
        <xs:element name="id" type="xs:string" />
.........
        <xs:element name="duration" type="durationType" />
        <xs:element name="order" type="xs:int" />
        <xs:element name="min-sub-period" type="xs:int" />
        <xs:element name="balance-impacts" minOccurs="0">
            <xs:complexType>
                <xs:sequence>
                    <xs:element name="balance-impact" type="charging-resourceType"
                        minOccurs="0" maxOccurs="unbounded" />
                </xs:sequence>
            </xs:complexType>

                    <xs:element name="balance-impact-rate" minOccurs="0"
                        maxOccurs="unbounded">

                                <xs:element name="rate" type="xs:double" />
                            </xs:sequence>
