JAXB绑定 - “无法兑现此转换定制” [英] JAXB binding - "unable to honor this conversion customization"

问题描述

我有我自己的complexType在模式中应该看起来像这样的 XML ：

<动态-content language-id =en_US><！ - [CDATA [256]] - >< / dynamic-content>

因此，包含一些文本的元素总是包含在CDATA中并具有属性。这是我迄今为止在 article-content.xsd 中所做的：

 <？ xml version =1.0encoding =UTF-8？> 
< xs：schema xmlns：xs =http://www.w3.org/2001/XMLSchema
 targetNamespace =http://www.ibacz.eu/veraext/xsd
 xmlns：tns =http://www.ibacz.eu/veraext/xsdelementFormDefault =qualifiedattributeFormDefault =unqualified> 
 
< xs：complexType name =cdata> 
< xs：attribute name =language-idtype =xs：string/> 
< / xs：complexType> 
 
< xs：element name =root> 
< xs：complexType> 
< xs：sequence> 
< xs：element name =dynamic-elementmaxOccurs =unbounded> 
< xs：complexType> 
< xs：sequence> 
< xs：element name =dynamic-contenttype =tns：cdata/> 
< / xs：sequence> 
< xs：attribute name =nametype =xs：string/> 
< xs：attribute name =indextype =xs：integer/> 
< xs：attribute name =typetype =xs：string/> 
< xs：attribute name =index-typetype =xs：string/> 
< / xs：complexType> 
< / xs：element> 
< / xs：sequence> 
< xs：attribute name =available-localestype =xs：string/> 
< xs：attribute name =default-localetype =xs：string/> 
< / xs：complexType> 
< / xs：element> 
< / xs：schema> 
  

和 bindings.xsd ：

 < jaxb：bindingings xmlns：jaxb =http://java.sun.com/xml/ns/jaxbxmlns：xs =http：// www.w3.org/2001/XMLSchema
 xmlns：xjc =http://java.sun.com/xml/ns/jaxb/xjcxmlns：xsi =http：//www.w3。 org / 2001 / XMLSchema-instance
 xsi：schemaLocation =http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0。 xsd
 version =2.1> 
 
< jaxb：bindings schemaLocation =article-content.xsdnode =/ xs：schema> 
< jaxb：bindings node =xs：complexType [@ name ='cdata']> 
< xjc：javaType name =Stringadapter =eu.ibacz.veraext.backofficebridge.core.util.AdapterCDATA/> 
< / jaxb：bindings> 
< / jaxb：bindings> 
 
< / jaxb：bindings> 
  

我无法摆脱的是编译器无法兑现转换定制。它附加到错误的地方，或者与其他绑定不一致。

请问我该怎么办？我正在与这个问题打几个小时，这对我来说是一个真正的阻挡。

解决方案

作为部分答案，你需要修复您的 cdata 类型，以便您可以使用文本内容：

  < complexType name =cdata> 
< simpleContent> 
< extension base =string> 
< attribute name =languagetype =string/> 
< / extension> 
< / simpleContent> 
< / complexType> 
  

离开我不知道你需要在绑定文件中定位哪个节点，但是你可以尝试 simpleContent 。

I have my own complexType in schema that should look in XML something like this:

<dynamic-content language-id="en_US"><!--[CDATA[256]]--></dynamic-content>

Therefore element containing some text always wrapped in CDATA and having attribute. This is what I've done so far in article-content.xsd:

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.ibacz.eu/veraext/xsd"
xmlns:tns="http://www.ibacz.eu/veraext/xsd" elementFormDefault="qualified" attributeFormDefault="unqualified">

    <xs:complexType name="cdata">
        <xs:attribute name="language-id" type="xs:string" />
    </xs:complexType>

    <xs:element name="root"> 
        <xs:complexType>
            <xs:sequence>
                <xs:element name="dynamic-element" maxOccurs="unbounded">
                  <xs:complexType>
                    <xs:sequence>
                        <xs:element name="dynamic-content" type="tns:cdata" />
                    </xs:sequence>
                    <xs:attribute name="name" type="xs:string" />
                    <xs:attribute name="index" type="xs:integer" />
                    <xs:attribute name="type" type="xs:string" />
                    <xs:attribute name="index-type" type="xs:string" />
                  </xs:complexType>
                </xs:element>
            </xs:sequence>
            <xs:attribute name="available-locales" type="xs:string" />
            <xs:attribute name="default-locale" type="xs:string" />
        </xs:complexType>
    </xs:element>
</xs:schema>

and bindings.xsd:

<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
           version="2.1">

    <jaxb:bindings schemaLocation="article-content.xsd" node="/xs:schema">
        <jaxb:bindings node="xs:complexType[@name='cdata']">
            <xjc:javaType name="String" adapter="eu.ibacz.veraext.backofficebridge.core.util.AdapterCDATA"/>
        </jaxb:bindings>
    </jaxb:bindings> 

</jaxb:bindings>

What I can't get rid of is compiler was unable to honor this conversion customization. It is attached to a wrong place, or its inconsistent with other bindings.

Please what should I do? I'm fighting with this problem for hours and it is a real blocker for me.

解决方案

As a partial answer you need to fix your cdata type as follows so you can have text content:

    <complexType name="cdata">
        <simpleContent>
            <extension base="string">
                <attribute name="language" type="string"/>
            </extension>
        </simpleContent>
    </complexType>

Off hand I'm not sure which node you need to target in the binding file, but you could try simpleContent.
