升级Jakarta JAXB后继承命名空间不支持问题求助

问题背景 #

将XSD转换为Java文件，升级至Jakarta JAXB后，配置继承扩展时遇到命名空间不支持的报错。

现有配置 #

XJB绑定文件配置 #

<jaxb:bindings version="3.0"
xmlns:jaxb="https://jakarta.ee/xml/ns/jaxb"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:xs="http://www.w3.org/2001/XMLSchema" 
xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
jaxb:extensionBindingPrefixes="inheritance">
<jaxb:globalBindings>
<xjc:simple />
<jaxb:javaType name="java.lang.String" xmlType="xs:date" />
<jaxb:javaType name="java.lang.String" xmlType="xs:time" />
<jaxb:serializable />
</jaxb:globalBindings>
<jaxb:bindings schemaLocation="&xsdPath;/sample.xsd">
<jaxb:bindings node="//xs:element[@name='sampleRequest']/xs:complexType">
<inheritance:implements>&baseRequest;</inheritance:implements>
</jaxb:bindings>
<jaxb:bindings node="//xs:element[@name='sampleResponse']/xs:complexType">
<inheritance:implements>&baseResponse;</inheritance:implements>
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>

Maven插件配置 #

报错现象 #

1. 初始构建报错：

"Unsupported binding namespace http://jaxb2-commons.dev.java.net/basic/inheritance. Perhaps you meant http://jaxb.dev.java.net/plugin/code-injector?"

2. 错误替换命名空间后，再次报错：

"Using http://jaxb.dev.java.net/plugin/code-injector customizations requires the "-Xinject-code" switch to enable this plug-in."

解决步骤 #

1. 补充继承插件依赖 #

在Maven插件的<dependencies>节点中添加适配Jakarta JAXB 3.x的继承扩展包：

<dependency>
    <groupId>org.jvnet.jaxb2_commons</groupId>
    <artifactId>jaxb2-basics</artifactId>
    <version>1.12.0</version>
</dependency>
<dependency>
    <groupId>org.jvnet.jaxb2_commons</groupId>
    <artifactId>jaxb2-basics-tools</artifactId>
    <version>1.12.0</version>
</dependency>

2. 恢复XJB文件的正确命名空间 #

将XJB文件中inheritance的命名空间恢复为http://jaxb2-commons.dev.java.net/basic/inheritance，无需替换为代码注入插件的命名空间——两者属于不同扩展，不能混用。

3. 重新执行构建 #

保持Maven插件<args>中的-Xinheritance参数不变，执行mvn clean compile即可正常生成带有继承实现的Java类。
