JAXBException：类上不是有效的属性
2022-09-04 04:07:41
我们有一个应用程序需要使用外部Web服务。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，我们希望设置用于运行时 Web 服务调用的终结点（以满足测试环境中不同的 Web 服务终结点 URL），因此编写了一些代码，如下所示为我们执行此操作：
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，并使用以下执行：

在底部，我可以看到javax.xml.bind.JAXBException：ProcessUIRequestResult不是类ZZZ上的有效属性。YYYwebservice.v5.types.ProcessUIRequestResponse 表明生成的 ProcessUIRequestResponse.java文件有问题。
我已经查看了该文件，看不到任何明显的东西（ProcessUIRequestResult在类中定义，并且具有getter和setter）。该类如下：
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;
import javax.xml.bind.annotation.XmlType;
import YYY.ZZZbase.BaseVO;

* </sequence>
* </restriction>
* </complexContent>

*/
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"processUIRequestResult"
})
@XmlRootElement(name = "ProcessUIRequestResponse")
public class ProcessUIRequestResponse {
@XmlElement(name = "ProcessUIRequestResult")
protected BaseVO processUIRequestResult;
/**
* Gets the value of the processUIRequestResult property.
*
* @return
* possible object is
* {@link BaseVO }
*
*/
public BaseVO getProcessUIRequestResult() {
return processUIRequestResult;
}
/**
* Sets the value of the processUIRequestResult property.
*
* @param value
* allowed object is
* {@link BaseVO }
*
*/
public void setProcessUIRequestResult(BaseVO value) {
this.processUIRequestResult = value;
}
public ProcessUIRequestResponse withProcessUIRequestResult(BaseVO value) {
setProcessUIRequestResult(value);
return this;
}
}
有没有人知道问题可能是什么？我无法发现任何明显的东西，也无法找到有关问题可能是什么的任何信息。
提前感谢您的帮助。
编辑 - 根据洛伦佐的回答更新20/09
不幸的是，Web服务是第三方服务，我无权修改XSD。在从 WSDL 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将属性更改为以大写字母开头以匹配 WSDL，并抛出了相同的错误。
有人有什么想法吗？
在26/09上进一步编辑以提供更新**
我一直在对此进行更多调查，发现它实际上看起来是服务终结点接口生成方式的问题。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注释和空白目标命名空间。当我手动编辑类并添加我期望的目标命名空间时（基于在XSD中的查找），我可以成功地调用Web服务。
我已经在XSD中查找了任何缺失的命名空间定义或任何其他明显的错误，但我无法发现任何内容。有没有人有任何关于目标命名空间或@WebResult从哪里生成的指针？
