JAXBException：不是类上的有效属性

2018-06-04 23:49:55

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生成一组Java工件。

在应用程序中，我们希望设置端点以用于运行时的Web服务调用（以满足测试环境中不同的Web服务端点URL），因此我们已经编写了一些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，它会在serviceFactory.getPort行上失败并执行以下命令：

在底部，我可以看到javax.xml.bind.JAXBException：ProcessUIRequestResult不是类ZZZ.YYYwebservice.v5.types.ProcessUIRequestResponse上的有效属性，这表明生成的ProcessUIRequestResponse.java文件存在问题。

我看过那个文件，看不到任何明显的东西（ProcessUIRequestResult在类中定义并且有一个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;
import javax.xml.bind.annotation.XmlType;
import YYY.ZZZbase.BaseVO;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "processUIRequestResult"
})
@XmlRootElement(name = "ProcessUIRequestResponse")
public class ProcessUIRequestResponse {

    @XmlElement(name = "ProcessUIRequestResult")
    protected BaseVO processUIRequestResult;

    /**

     * 
     * @return
     *     possible object is

     *     
     */
    public BaseVO getProcessUIRequestResult() {
        return processUIRequestResult;
    }

    /**
     * Sets the value of the processUIRequestResult property.
     *

     *     allowed object is

    public void setProcessUIRequestResult(BaseVO value) {
        this.processUIRequestResult = value;
    }

    public ProcessUIRequestResponse withProcessUIRequestResult(BaseVO value) {
        setProcessUIRequestResult(value);
        return this;
    }

}

有谁知道这个问题会是什么？我无法发现任何明显的信息，也无法找到任何有关问题的信息。

感谢您的帮助提前。

编辑 - 基于洛伦佐的回答于20/09年更新

不幸的是，Web服务是第三方服务，我无权修改XSD。在从中生成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并引发相同的错误。

有没有人有任何想法？

我一直在对此进行更多的调查，发现它实际上是服务端点接口生成方式的问题。这是生成的内容：

/**

@WebService(targetNamespace = "http://zzz/yyywebservice/v5/types/", name = "Types")
@XmlSeeAlso({ zzz.yyyentityview.ObjectFactory.class, zzz.yyyview.search.postcode.ObjectFactory.class,
        zzz.yyyentityview.validation.ObjectFactory.class, zzz.serializable_dictionary.ObjectFactory.class,
        zzz.yyyview.search.app.ObjectFactory.class, zzz.yyybase.ObjectFactory.class, zzz.yyybase.enums.ObjectFactory.class,

        zzz.yyyentityview.client.ObjectFactory.class, ObjectFactory.class })
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);
}

问题出在@WebResult注释和空白targetNamespace上。当我手动编辑类并添加我期望的targetNamespace（基于查看XSD）时，我可以成功调用Web服务。

我在XSD中查找了任何缺少的名称空间定义或任何其他明显的错误，但我无法找到任何东西。有没有人有任何关于targetNamespace或@WebResult从哪里生成的指针？

这可能是wsdl2java如何命名包的问题。如果targetNamespace（wsdl）是骆驼大小写符号，那么你的包也需要骆驼大小写。例如：

对于targetNamespace =“http：//your.domain/WebAdminServices/WebSiteMgmt”

包domain.your.webAdminServices.webSiteMgmt; - >工作:)

包domain.your.webadminservices.websitemgmt; - >不工作:(

希望能帮助到你，

我有类似的问题，我发现这个链接上的东西，你应该尝试以下几点：

添加package-info.java构建路径

为您的服务编译并导入新的package-info.java，并将不同的服务保存在不同的服务中

从wsdl下载新的package-info.java文件

Javabean属性名称通常是小写字母。您的WSDL中有一个大写的标记名称，即ProcessUIRequestResult ，但在您的类中有一个小写属性processUIRequestResult ，由方法名称setProcessUIRequestResult和getProcessUIRequestResult表示。

WSDL到Java代码的生成似乎是正确的，但并不意味着其他库代码将遵守WSDL和/或Java注释。

你可以使用小写元素名称吗？
