java - 如何使用带有名称冲突的 maven-jaxb2-plugin 映射 wsdl

Question

我在将 Web 服务映射到 Java POJO 时遇到问题，因为它包含两个元素:

• 标签1
• label_1

当插件将其转换为 java POJO 时，名称中的下划线将被删除，导致生成的类中出现重复字段。

[ERROR] Error while generating code.Location [ file:/C:/PrivateWS/test-project/sources/target/wsdl/test.wsdl{12,94}]. com.sun.istack.SAXParseException2; systemId: file:/C:/PrivateWS/test-project/sources/target/wsdl/test.wsdl; lineNumber: 12; columnNumber: 94; Two declarations cause a collision in the ObjectFactory class.

我尝试使用外部绑定(bind)文件将其中一个元素重命名为其他名称，但失败了。 我查看了很多不同的论坛，但找不到任何似乎有效的解决方案。据我所知，该属性未被识别，这会导致以下错误。

[ERROR] Error while parsing schema(s).Location [ file:/C:/PrivateWS/test-project/sources/target/classes/bindings.xjb{9,46}]. com.sun.istack.SAXParseException2; systemId: file:/C:/PrivateWS/test-project/sources/target/classes/bindings.xjb; lineNumber: 9; columnNumber: 46; compiler was unable to honor this property customization. It is attached to a wrong place, or its inconsistent with other bindings.

为了使字段重命名有效，我做错了什么？

更改 wsdl 不是一个选项，因为它是第三方 wsdl。

Answer 1

您是否设置了 underscoreBinding 并尝试过？

<jxb:bindings schemaLocation="*">
    <jxb:globalBindings underscoreBinding="asCharInWord" />
</jxb:bindings>
