jaxb2 简化插件绑定问题

Question

我尝试使用 XJC 2.2.4 使用 JAXB2 简化插件。

D:\>xjc -d . -extension -p org.my.space sample.xsd parsing a schema... [ERROR] Unsupported binding namespace
"http://jaxb2-commons.dev.java.net/basic/simplify". Perhaps you meant
"http://jaxb.dev.java.net/plugin/code-injector"?   line 7 of file:/D:/sample.xsd
Failed to parse a schema.

sample.xsd 有声明的简化

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.1"
    xmlns:simplify="http://jaxb2-commons.dev.java.net/basic/simplify"
    jaxb:extensionBindingPrefixes="simplify"
    xmlns="http://www.example.org/sampleXML" targetNamespace="http://www.example.org/sampleXML"
    elementFormDefault="qualified">

有什么想法吗？

编辑： 我用绑定文件 xjb 尝试了其他方法，但仍然是同样的错误。这是否意味着我的 XJC 版本（2.2）不支持 JAXB2 简化？

xjc -d 。 -extension -b bindings.xjb sample.xsd

<bindings version="2.1"
      xmlns="http://java.sun.com/xml/ns/jaxb"
      xmlns:xs="http://www.w3.org/2001/XMLSchema"
      xmlns:simplify="http://jaxb2-commons.dev.java.net/basic/simplify"
      extensionBindingPrefixes="simplify">

    <bindings schemaLocation="sample.xsd" node="/xs:schema">
        <bindings
            node="/xs:schema/xs:complexType[@name='dlist']/xs:choice/xs:element[1]">
            <simplify:as-element-property />
        </bindings>
    </bindings>

</bindings>

我切换到maven jaxb2 plugin 并且经过更多努力，它运行良好。对于未来有困难的人。此设置在 JDK 1.6 中运行良好（适用于仍无法迁移的用户）。

pom.xml

            </plugin>
        </plugins>
    </build>

我没有使用binding.xjb，因为我已将simplify 直接包含在架构中（因为我有权访问）。

sample.xsd

<xs:complexType name="doclist">
    <xs:sequence>
        <xs:choice minOccurs="0" maxOccurs="unbounded">
            <xs:annotation>
                <xs:appinfo>
                    <simplify:as-element-property />
                </xs:appinfo>
            </xs:annotation>
            <xs:element name="document1" type="type1" />
            <xs:element name="document2" type="type2" />
        </xs:choice>
    </xs:sequence>
    <xs:attribute name="heading" type="xs:string" />
</xs:complexType>
