我正在尝试使用 JiBX Code Gen 工具为[OTA2003B] ( http://www.opentravel.org/Specifications/SchemaIndex.aspx?FolderName=2003B ) 上可用的 OTA 模式生成代码(应用了自定义)。以下是代码我已经写了实现同样的目标。

Maven pom.xml jibx-maven-plugin 配置

自定义 XML:custom1.xml

<schema-set xmlns:xs="http://www.w3.org/2001/XMLSchema"
        prefer-inline="true" 
        type-substitutions="xs:integer xs:int xs:decimal xs:float"
        binding-per-schema="true">
    <schema name="FS_OTA_VehAvailRateRQ.xsd" 
            includes="OTA_VehAvailRateRQ"
            binding-file-name="otaVehAvailRateRQ_binding.xml"
            package="com.poc.jibx.vehAvailRateRQ"/>
    <schema name="FS_OTA_VehAvailRateRS.xsd" 
            includes="OTA_VehAvailRateRS"
            binding-file-name="otaVehAvailRateRS_binding.xml"
            package="com.poc.jibx.vehAvailRateRS"/>
</schema-set>

当我尝试从配置的模式生成代码时,代码会在没有绑定文件的情况下生成,并且出现以下错误:

我可以看到,在两个模式中都指定了上面显示的错误中提到的元素,例如InventoryStatusType可用。因此,问题正在发生。但我已经指定了prefer-inline="true"和不同的包要在我的custom1.xml中生成的每个模式代码,这意味着对于这两个模式,InventoryStatusType的完全限定名称(假设这将被创建为内部类)将是不同的,这不应该像这样创建一个重复错误我正在遇到。
1)是什么导致了问题以及generate-all="false"如何能够避免这个问题?
2) 如何在不使用generate-all="false" 的情况下解决 Duplicate Name 错误?

注意:使用 generate-all="false" 生成绑定文件但在编译绑定时遇到以下错误:

收到Don的回复后对此进行更新

发布问题后,我在线查看了 OTA 模式 ( http://www.opentravel.org/Specifications/SchemaIndex.aspx?FolderName=2003B ) 我试图从中生成代码,我发现上面的链接和我所拥有的不同。所以我认为我拥有的扁平化版本的架构可能会导致问题。所以我下载了架构的在线版本,它的结构正确,因为它包含常见的架构,即

<xs:include schemaLocation="OTA_VehicleCommonTypes.xsd"/>
<xs:include schemaLocation="OTA_SimpleTypes.xsd"/>
<xs:include schemaLocation="OTA_CommonTypes.xsd"/>
<xs:include schemaLocation="OTA_CommonPrefs.xsd"/>
<xs:include schemaLocation="OTA_AirCommonTypes.xsd"/>

注意:我没有在我的代码中使用 OTA_AirCommonTypes.xsd,因为在此架构定义中发生了与架构元素相关的一些错误。

所以我认为现在提到的模块化生成技术(http://jibx.sourceforge.net/fromschema/example-modular.html)可以提供帮助。我继续进行相同的操作,以下是我编写的代码:

jibx-maven-plugin 配置

                  </options>
            </configuration>

我的自定义 XML

custom_a.xml

<schema-set prefer-inline="true" package="com.poc.jibx.ota.common"
        xmlns:xs="http://www.w3.org/2001/XMLSchema"
        type-substitutions="xs:integer xs:int xs:decimal xs:float"
        binding-file-name="base-binding.xml">

  <schema name="OTA_VehicleCommonTypes.xsd">
     <complexType name="VehicleProfileRentalPrefType">
    <element path="**" name="VendorPref" ignore="true"/>
    </complexType>
  </schema>

</schema-set>

custom_b.xml

<schema-set prefer-inline="true" 
        xmlns:xs="http://www.w3.org/2001/XMLSchema"
        type-substitutions="xs:integer xs:int xs:decimal xs:float" >

   <name-converter strip-prefixes="OTA_"

    <schema name="OTA_VehAvailRateRS.xsd" 
        includes="OTA_VehAvailRateRS" binding-file-name="otaVehAvailRateRS_binding.xml"
        package="com.poc.jibx.ota.vehAvailRateRS" />             
</schema-set>

首先,我应用了生成代码的custom_a.xml并运行了成功编译绑定(base-binding.xml)的 jibx:bind 目标。然后我评论了应用 custom_a.xml 的配置部分,并启用了应用custom_b.xml的配置部分, 它成功生成了代码,但运行绑定编译器产生了以下错误:

那么现在我错过了什么或出错了,以及如何解决这个问题?另外,我编写的代码是否符合 JiBX 用户应遵循的最佳实践,或者我可以做出哪些改进?

笔记:

吉涅什,

当您使用平面模式(以 FS_ 为前缀的模式)时,最好不要一次编译多个模式,因为所有包含的模式都将在每个顶级模式中重复。

由于无论如何您都想要不同的包名称,请将其拆分为两个项目,其中一个包括:

<includeSchemas>
    <includeSchema>FS_OTA_VehAvailRateRQ.xsd</includeSchema>
</includeSchemas>

另一个包括这个:

<includeSchemas>
    <includeSchema>FS_OTA_VehAvailRateRS.xsd</includeSchema>
</includeSchemas>

这是在不使用 generate-all="false" 的情况下解决重复名称错误的最简单方法。
