我有两个用于不同服务的 WSDL 文件。两种服务都可以独立工作，但是如果我在同一个 eclipse 项目中包含这两种服务，我会收到以下错误的几个实例：

There's no ObjectFactory with an @XmlElementDecl for the element {http://schemas.foobar.com/oms/2010/10/Models}City.
    this problem is related to the following location:
        at protected javax.xml.bind.JAXBElement com.foobar.schemas.oms._2010._10.models.BusinessUnitData.city
        at com.foobar.schemas.oms._2010._10.models.BusinessUnitData
        at protected com.foobar.schemas.oms._2010._10.models.BusinessUnitData com.foobar.schemas.oms._2010._10.businessunit.CreateBusinessUnitRequest.businessUnitData

        at public com.foobar.schemas.oms._2010._10.businessunit.CCreateBusinessUnitRequest com.foobar.schemas.oms._2010._10.businessunit.ObjectFactory.createCCreateBusinessUnitRequest()

        at @javax.xml.bind.annotation.XmlSeeAlso(value=[class com.foobar.schemas.oms._2010._10.businessunit.AddToStructureRequest])

这些错误完全填满了我的终端窗口，所以我不知道这种情况发生了多少次。

我正在以两种方式之一生成存根代码。首先，我尝试使用 wsdl2java 生成两者，然后将编译后的代码打包到一个 jar 中，并将其包含在我的构建路径中。我还尝试使用 cxf code-gen 插件创建一个新的 maven 项目。然后我运行“mvn install”并将生成的代码作为 maven 依赖项包含在内。两种技术产生相同的结果。每项服务都可以独立运行。但如果两者都包含在项目中，我会收到对象工厂错误。

是什么导致了这种类型的错误？可以用 jaxb 绑定文件修复吗？如果是这样，我是 web 服务的新手，并且一直无法找到示例绑定文件来学习如何格式化它。

使用这个 maven 插件从 WSDL 生成类：

            </goals>
        </execution>
    </executions>
</plugin>

并为您拥有的每个 WSDL 文件指定不同的包。根据不同的 WSDL 文件生成的所有类都将在不同的包中生成，您不会遇到任何冲突。
