使用JAXB编译包含相同元素的重复定义的多个XSD [英] Compile several XSD's containing duplicate definitions of the same element with JAXB

问题描述

问题：
如何让xjc / Jaxb为同一名称空间中包含重复元素定义的多个模式生成propper javaclasses？

Question: How do i make xjc/Jaxb generate the propper javaclasses for several schemas containing duplicate elementdefinitions in the same namespace?

信息：
我有三个.xsd架构：A，B和C.所有都有相同的targetnamespace。
他们都是给我的3个shemas，我不会以任何方式允许以任何方式改变它们。

Information: I have three .xsd schemas: A,B and C. All have the same targetnamespace. They are all 3 shemas that has been given to me, and i am not, in any way possible, allowed to change them in any way.

他们A有一些元素也可以在B或C中找到（但A也有很多自我声明的元素）
示例：这与A和C的代码相同：

They A has some elements that is also found in B or C (but A has a lot of self declared elements as well) Example: This is the same "code" for A and C:

<xs:simpleType name="y_ym_ymdDatoType">
    <xs:union memberTypes="arcgYearType arcgYearMonthType arcDateType"/>
</xs:simpleType>
<xs:simpleType name="arcgYearType">
    <xs:restriction base="xs:gYear">
        <xs:minInclusive value="1700"/>
        <xs:maxInclusive value="2100"/>
    </xs:restriction>
</xs:simpleType>
<xs:simpleType name="arcgYearMonthType">
    <xs:restriction base="xs:gYearMonth">
        <xs:minInclusive value="1700-01"/>
        <xs:maxInclusive value="2100-12"/>
    </xs:restriction>
</xs:simpleType>
<xs:simpleType name="arcDateType">
    <xs:restriction base="xs:date">
        <xs:minInclusive value="1700-01-01"/>
        <xs:maxInclusive value="2100-12-31"/>
    </xs:restriction>
</xs:simpleType>

当使用xjc将它们编译成javaclasses时，我得到以下异常：

When using xjc to compile them into javaclasses, i get the following exception:

[ERROR] 'y_ym_ymdDatoType' is already defined
 line 297 of file:../c.xsd

[ERROR] (related to above error) the first definition appears here
 line 309 of file:../a.xsd

并且其他元素也是如此：arcgYearType，arcgYearMonthType和arcDateType。

and the same happens to the other elements: arcgYearType, arcgYearMonthType and arcDateType.

我读过一篇可能解决这个问题的绑定文件问题，但我不知道怎么做，所以示例将是首选。

I have read about a binding file that maybe could solve this problem, but i am not sure on how to do it so examples will be highly preferred.

推荐答案

您可以使用手动解决冲突绑定文件。下面是一个示例，您可以在其中为冲突名称指定自定义名称：

You can resolve conflicts manually using binding file. Here is the example, where you can specify your custom name for conflicting names:

<bindings schemaLocation="../party.xsd" version="1.0" node="/xs:schema">
    <bindings node="//xs:complexType[@name='FixedIncomeBook']">
        <class name="PartyFixedIncomeBook"/>
    </bindings>
</bindings>
