导入命名空间 - 无法将名称解析为（n）'类型定义'组件 [英] Import namespace - Cannot resolve the name to a(n) 'type definition' component

问题描述

上下文：我使用maven-jaxb插件从xsd文件生成java类。我的所有.xsd文件都在一个位置 - src / main / resource目录。

Context: I am generating java classes from xsd files using maven-jaxb plugin. All my .xsd files are in a single location - src/main/resource directory.

问题：当xsd没有引用/导入具有不同目标命名空间的其他xsd时，一切正常。但是当下面的xsd（使用targetNamespace =http://www.companyA.com/someservice）从另一个命名空间（namespace =http://www.companyB.com/）导入另一个xsd filename.xsd时，我得到上面的错误：无法将名称xxx解析为（n）'类型定义'组件。

Problem: Everything works fine when xsd's don't reference/import other xsd's with a different target namespace. However when the following xsd below (with targetNamespace="http://www.companyA.com/someservice") imports another xsd filename.xsd from a different namespace (namespace="http://www.companyB.com/"), I get the above error: Cannot resolve the name xxx to a(n) 'type definition' component.

编辑：当前xsd文件中的元素名称是' entityName'，它的类型是companyB：entityName（即）名称是相同的。

the element name in the current xsd file is 'entityName', and its type is "companyB:entityName" (i.e.) the names are the same.

然后我尝试从命令行调用此文件上的xjc正确生成Java类。我还确保在Eclipse中，我可以在type =companyCdm：entityName上按住Ctrl键单击/检查源代码，它正确地打开了filename.xsd文件。但是由于某些原因，maven无法访问它。

I then tried invoking xjc on this file from the command line and this generated Java classes correctly. I also made sure that in Eclipse, I am able to ctrl-click/examine source on "type="companyCdm:entityName", which correctly opens the filename.xsd file. However for some reason maven is unable to get to it.

问题：我缺少什么？为什么这种情况（2个名称空间）与处理单个名称空间不同？

Question: What am I missing? Why is this case (2 namespaces) different from dealing with a single namespace?

这是我的XSD：

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns="http://www.companyA.com/someservice"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:companyB="http://www.companyB.com/version"
    targetNamespace="http://www.companyA.com/someservice"
    elementFormDefault="qualified" attributeFormDefault="qualified">

    <xsd:import namespace="http://www.companyB.com/version" schemaLocation="filename.xsd" />

    <xsd:element name="MyName" type="MyType" />

    <xsd:complexType name="MyType">
        <xsd:annotation>
        <xsd:documentation>
            A list
        </xsd:documentation>
    </xsd:annotation>
    <xsd:sequence>
        <xsd:element name="entityName" type="companyB:entityName" maxOccurs="1" minOccurs="1"/>
    </xsd:sequence>
  </xsd:complexType>
</xsd:schema>

推荐答案

好的找到了解决办法：

我将所有依赖的xsd（有问题的xsd的引用）加上一堆其他未使用的xsd移动到一个单独的文件夹然后使用maven重新生成代码 - 它现在可以工作了。似乎存在一些与其他未使用的xsd之一的名称空间冲突，我还没有指出具体的那个。

I moved all the dependent xsd's (that the problematic xsd's references) plus a bunch of other un-used xsds to a separate folder and then re-generated code using maven - it works now. It appears that there was some namespace conflict with one of the other un-used xsd's i haven't yet pointed out the specific one.
