jaxb2简化了插件绑定问题 [英] jaxb2 simplify plugin binding issue

问题描述

我尝试使用XJC 2.2.4使用JAXB2简化插件。

I tried to use JAXB2 simplify plugin using the XJC 2.2.4.

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具有声明的简化

sample.xsd has the declared simplify

<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：
我尝试使用绑定文件xjb的其他方法仍然是相同的错误。这是否意味着我的XJC版本（2.2）不支持JAXB2简化？

I tried other way around with bindings file xjb and still the same error. Does it mean my XJC version(2.2) does not support JAXB2 simplify ?

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

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>

推荐答案

我切换到 maven jaxb2插件并且通过更多的努力它运行良好。对于将来遇到麻烦的人。这个设置在JDK 1.6中运行得很好（对于那些仍然无法迁移的人）。

I switched to maven jaxb2 plugin and with some more efforts it worked fine. For people who have trouble in future. This setup works just fine in JDK 1.6 (for those still cant migrate).

我没有使用 binding.xjb as我已直接在架构中包含简化（因为我有权访问）。

I did not use binding.xjb as I have included the simplify directly in the schema (as i have access).

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>
