如何通过jaxb bindings.xml来区分重复的元素 [英] How to differenciate duplicate elements through jaxb bindings.xml

问题描述

我必须处理一个xsd模式，以通过jaxb生成java代码，并且在其中一个序列中有两个相同名称的元素。这导致麻烦，我来到使用bindings.xml来区分两个元素。

我的问题是，我无法设法定位一个单一的元素为此目的，它是针对我想要的元素加另一个compleType的另一个元素。

这是我的bindings.xml

 < jxb：bindings version =2.0
 xmlns：jxb =http://java.sun.com/xml/ns/jaxb
 xmlns： xsd =http://www.w3.org/2001/XMLSchema
 xmlns：xs =http://www.w3.org/2001/XMLSchema> 
< jxb：bindings schemaLocation =FLUTE-FDT-3GPP-2005-Extensions.xsdnode =/ xsd：schema> 
< jxb：bindings node =// xsd：complexType [@ name ='MBMS-Session-Identity-Expiry-Type']> 
< jxb：bindings node =.// xsd：attribute [@ name ='value']> 
< jxb：property name =requiredValue/> 
< / jxb：bindings> 
< / jxb：bindings> 
< / jxb：bindings> 
< jxb：bindings schemaLocation =mbms-flute-release11.xsdnode =/ xs：schema> 
< jxb：bindings node =// xs：complexType [@ name ='FileType']> 
< jxb：bindings multiple =truenode =// xs：element [2]> 
< jxb：property name =delimiter1/> 
< / jxb：bindings> 
< / jxb：bindings> 
< / jxb：bindings> 
  

因此，分隔符元素正确地重命名为delimiter1，但是schemaVersion元素也被重命名为delimiter1！

有什么建议吗？

编辑1

根据我的建议，使用 @ref bindings.xml如下所示：

 < jxb：bindings version =2.0
 xmlns：jxb = http://java.sun.com/xml/ns/jaxb
 xmlns：xsd =http://www.w3.org/2001/XMLSchema
 xmlns：xs =http： //www.w3.org/2001/XMLSchema\"> 
< jxb：bindings schemaLocation =FLUTE-FDT-3GPP-2005-Extensions.xsdnode =/ xsd：schema> 
< jxb：bindings node =// xsd：complexType [@ name ='MBMS-Session-Identity-Expiry-Type']> 
< jxb：bindings node =.// xsd：attribute [@ name ='value']> 
< jxb：property name =requiredValue/> 
< / jxb：bindings> 
< / jxb：bindings> 
< / jxb：bindings> 
< jxb：bindings schemaLocation =mbms-flute-release11.xsdnode =/ xs：schema> 
< jxb：bindings node =// xs：complexType [@ name ='FileType']> 
< jxb：bindings multiple =truenode =// xs：element [@ ref ='sv：delimiter'] [1]> 
< jxb：property name =delimiter1/> 
< / jxb：bindings> 
< jxb：bindings node =// xs：element [@ ref ='sv：delimiter'] [2]> 
< jxb：property name =delimiter2/> 
< / jxb：bindings> 
< / jxb：bindings> 
< / jxb：bindings> 
< / jxb：bindings> 
  

现在，它重命名所有出现的 sv：delimiter （文档中的3），而不是FileType复合类型中的那些。
比以前更好，但是我想只能重命名所选元素，而不是全部。

解决方案

感谢Xstian，这是解决方案：

 < jxb：bindings version =2.0
 xmlns：jxb =http://java.sun.com/xml/ns/jaxb
 xmlns：xsd =http：// www .w3.org / 2001 / XMLSchema
 xmlns：xs =http://www.w3.org/2001/XMLSchema> 
< jxb：bindings schemaLocation =FLUTE-FDT-3GPP-2005-Extensions.xsdnode =/ xsd：schema> 
< jxb：bindings node =// xsd：complexType [@ name ='MBMS-Session-Identity-Expiry-Type']> 
< jxb：bindings node =.// xsd：attribute [@ name ='value']> 
< jxb：property name =requiredValue/> 
< / jxb：bindings> 
< / jxb：bindings> 
< / jxb：bindings> 
< jxb：bindings schemaLocation =mbms-flute-release11.xsdnode =/ xs：schema> 
< jxb：bindings node =// xs：complexType [@ name ='FileType'] // xs：element [@ ref ='sv：delimiter'] [1]> 
< jxb：property name =delimiter1/> 
< / jxb：bindings> 
< jxb：bindings node =// xs：complexType [@ name ='FileType'] // xs：element [@ ref ='sv：delimiter'] [2]> 
< jxb：property name =delimiter2/> 
< / jxb：bindings> 
< / jxb：bindings> 
< / jxb：bindings> 
  

谢谢

解决方案

尝试使用例如

 < jxb：bindings schemaLocation =mbms-flute-release11.xsd节点= / XS：模式 > 
< jxb：bindings node =// xs：complexType [@ name ='FileType']> 
< jxb：bindings node =// xs：element [@ ref ='mbms2012：Alternate-Content-Location-1']> 
< jxb：property name =delimiter1/> 
< / jxb：bindings> 
< / jxb：bindings> 
< / jxb：bindings> 
  

或

 < jxb：bindings schemaLocation =mbms-flute-release11.xsdnode =/ xs：schema> 
< jxb：bindings node =// xs：complexType [@ name ='FileType'] // xs：element [@ ref ='mbms2012：Alternate-Content-Location-1']> 
< jxb：property name =delimiter1/> 
< / jxb：bindings> 
< / jxb：bindings> 
  

I have to deal with an xsd schema to generate the java code through jaxb and there is two elements withe same name in one of the sequence. This is causing troubles and i have come to use bindings.xml to differrenciate both elements.

My problem is that i can not manage to pinpoint one single element for this purpose, it is targetting the element i want plus another element from another compleType.

Here is my bindings.xml

<jxb:bindings version="2.0"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<jxb:bindings schemaLocation="FLUTE-FDT-3GPP-2005-Extensions.xsd" node="/xsd:schema">
    <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
        <jxb:bindings node=".//xsd:attribute[@name='value']">
            <jxb:property name="requiredValue"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>
<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']">
        <jxb:bindings multiple="true" node="//xs:element[2]">
            <jxb:property name="delimiter1"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

As a result, the first delimiter element is correctly renamed to delimiter1, but the schemaVersion element is also renamed to delimiter1!

Any suggestion on what is wrong?

EDIT 1

After using @ref as suggested by my bindings.xml looks like this :

<jxb:bindings version="2.0"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <jxb:bindings schemaLocation="FLUTE-FDT-3GPP-2005-Extensions.xsd" node="/xsd:schema">
        <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
            <jxb:bindings node=".//xsd:attribute[@name='value']">
                <jxb:property name="requiredValue"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
    <jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
        <jxb:bindings node="//xs:complexType[@name='FileType']">
            <jxb:bindings multiple="true" node="//xs:element[@ref='sv:delimiter'][1]">
                <jxb:property name="delimiter1"/>
            </jxb:bindings> 
            <jxb:bindings node="//xs:element[@ref='sv:delimiter'][2]">
                <jxb:property name="delimiter2"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

Now it renames all occurernces of sv:delimiter (3 in the document) instead of only those within FileType complexe type. It is better than before but i'd like to be able to only rename selected elements not all if possible.

Solution

Thanks to Xstian, this is the solution that is working :

<jxb:bindings version="2.0"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"

        <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
            <jxb:bindings node=".//xsd:attribute[@name='value']">
                <jxb:property name="requiredValue"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
    <jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
            <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='sv:delimiter'][1]">
                <jxb:property name="delimiter1"/>
            </jxb:bindings> 
            <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='sv:delimiter'][2]">
                <jxb:property name="delimiter2"/>
            </jxb:bindings> 
    </jxb:bindings>
</jxb:bindings>

Thanks

解决方案

Try to use for example

<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']">
        <jxb:bindings node="//xs:element[@ref='mbms2012:Alternate-Content-Location-1']">
            <jxb:property name="delimiter1"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

or

<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='mbms2012:Alternate-Content-Location-1']">
          <jxb:property name="delimiter1"/>
    </jxb:bindings>
</jxb:bindings>
