我们有一个需要使用外部 Web 服务的应用程序。为此，我们使用 cxf-codegen-plugin 插件提供的 wsdl2java 目标通过 Maven 从 WSDL 生成了一组 Java 工件。
在应用程序中，我们希望设置端点以在运行时用于 Web 服务调用（以适应测试环境中不同的 Web 服务端点 URL），因此编写了如下代码来为我们执行此操作：
private <T> T createServiceObject(final Class<T> p_seiClass) throws MalformedURLException {
final Service serviceFactory = Service.create(new URL(wsdlLocation), new QName(targetNamespace, serviceName));
final T service = serviceFactory.getPort(p_seiClass);
((BindingProvider) service).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "endpoint");
return service;
}
当代码运行时，它在 serviceFactory.getPort 行上失败，并带有以下执行：

在底部我可以看到javax.xml.bind.JAXBException: ProcessUIRequestResult is not a valid property on class ZZZ.YYYwebservice.v5.types.ProcessUIRequestResponse这表明生成的 ProcessUIRequestResponse.java 文件有问题。
我查看了那个文件，看不到任何明显的东西（ProcessUIRequestResult 是在类中定义的，并且有一个 getter 和 setter）。课程如下：
package YYY.ZZZwebservice.v5.types;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

/**

return processUIRequestResult;
}

public void setProcessUIRequestResult(BaseVO value) {
this.processUIRequestResult = value;
}
public ProcessUIRequestResponse withProcessUIRequestResult(BaseVO value) {
setProcessUIRequestResult(value);
return this;
}
}
有谁知道问题可能是什么？我找不到任何明显的东西，也找不到任何关于问题可能是什么的信息。
提前感谢您的帮助。
编辑 - 根据 LORENZO 的回答于 20/09 更新
不幸的是，Web 服务是第三方服务，我无权修改 XSD。从它生成 Java 时，我使用了 WSDL 的服务器 URL。
但是，作为测试，我修改了生成的 ProcessUIRequestResponse.java 以将属性更改为以大写字母开头以匹配 WSDL，并引发了相同的错误。
有没有人有任何想法？
26/09 进一步编辑以提供更新**
我一直在对此进行更多调查，并发现它实际上看起来是生成服务端点接口的方式的问题。这是生成的：
/**

@WebService(targetNamespace = "http://zzz/yyywebservice/v5/types/", name = "Types")

public interface Types {
@WebResult(name = "ProcessUIRequestResult", targetNamespace = "")
@ResponseWrapper(localName = "ProcessUIRequestResponse", targetNamespace = "http://zzz/yyywebservice/v5/types/", className = "zzz.yyywebservice.v5.types.ProcessUIRequestResponse")
@RequestWrapper(localName = "ProcessUIRequest", targetNamespace = "http://zzz/yyywebservice/v5/types/", className = "zzz.yyywebservice.v5.types.ProcessUIRequest")
@WebMethod(operationName = "ProcessUIRequest", action = "http://zzz/yyywebservice/v5/ProcessUIRequest")
public zzz.yyybase.BaseVO processUIRequest(
@WebParam(name = "ProcessUIRequest", targetNamespace = "http://zzz/yyywebservice/v5/types/") zzz.yyybase.BaseVO processUIRequest);
@WebResult(name = "GetActivityStatusEntityResult", targetNamespace = "")
@ResponseWrapper(localName = "GetActivityStatusEntityResponse", targetNamespace = "http://zzz/yyywebservice/v5/types/", className = "zzz.yyywebservice.v5.types.GetActivityStatusEntityResponse")
@RequestWrapper(localName = "GetActivityStatusEntity", targetNamespace = "http://zzz/yyywebservice/v5/types/", className = "zzz.yyywebservice.v5.types.GetActivityStatusEntity")
@WebMethod(operationName = "GetActivityStatusEntity", action = "http://zzz/yyywebservice/v5/GetActivityStatusEntity")
public zzz.yyybase.ActivityStatusVOBase getActivityStatusEntity(
@WebParam(name = "ProcessUIRequest", targetNamespace = "http://zzz/yyywebservice/v5/types/") zzz.yyybase.BaseVO processUIRequest);
}
问题在于 @WebResult 注释和空白的 targetNamespace。当我手动编辑类并添加我期望的 targetNamespace 时（基于查看 XSD），我可以成功调用 Web 服务。
我在 XSD 中查看了任何缺少的命名空间定义或任何其他明显的错误，但我什么也找不到。有没有人知道 targetNamespace 或 @WebResult 是从哪里生成的？
