我正在尝试使用 CXF WSDL2Java 将第 3 方 WSDL 文件（我无法更改）解析为 Java，但我遇到了异常（如下所示）。这个完全相同的异常重复了 7 次。它们完全相同。我猜问题出在 xsd 中，在那里我找到了几个这样的片段：
<xs:complexType name="CCTUserDetails">
<xs:sequence>
<xs:element minOccurs="0" name="CCTLogin" nillable="true" type="xs:string"/>
<xs:element minOccurs="0" name="CCTServerName" nillable="true" type="xs:string"/>
<xs:element minOccurs="0" name="Domain" nillable="true" type="xs:string"/>
<xs:element name="Enabled" nillable="true" type="xs:string"/>
<xs:element minOccurs="0" name="Password" nillable="true" type="xs:string"/>
<xs:element name="UserName" nillable="true" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:element name="CCTUserDetails" nillable="true" type="tns:CCTUserDetails"/>
调查错误，似乎我需要做一些自定义 JaxB 映射，但我完全不知道该怎么做。有人可以告诉我如何使用带有 CXFs WSDL2Java 的外部 JaxB 映射文件重命名复杂类型或元素来解决此错误吗？我将 cxf-codegen-plugin 与 maven 一起使用。
