JAXBException：不是类的有效属性

问题描述 投票：9回答：5

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，我们希望将端点设置为在运行时用于Web服务调用（以满足测试环境中的不同Web服务端点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，但有以下异常：

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文件出了问题。

我查看了那个文件并且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;

    /**
     * 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;
    }

}

有谁知道问题可能是什么？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。

编辑 - 基于LORENZO答案的20/09更新

遗憾的是，Web服务是第三方服务，我无权修改XSD。我从它生成Java时使用了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，并抛出相同的错误。

有没有人有任何想法？

在09/09进一步编辑以提供更新**

我一直在对此进行更多的调查，并发现它实际上看起来与生成服务端点接口的方式有关。这是生成的：

    @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targetNamespace。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。

我已经在XSD中查找了任何缺少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东西。有没有人有关于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）采用驼峰大小写表示法，那么你的包也必须是驼峰式的。例如。：

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

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

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

希望能帮助到你，

我有类似的问题，我在这个link上找到了一些东西，你应该尝试以下方法：

  1. 添加package-info.java构建路径
  2. 为您的服务编译和导入新的package-info.java，并将不同的服务保存在不同的服务中
  3. 从wsdl下载新的package-info.java文件

解决方法：改为使用jaxws-maven-plugin。 https://mvnrepository.com/artifact/org.codehaus.mojo/jaxws-maven-plugin

我的项目也发生了同样的问题。 cxf无法生成targetNamespace，但jaxws可以给出相同的wsdl文件。

只需像这样添加package-info.java：

package-info.Java :

@XmlSchema(
   namespace = "http://www.eijux.com/webservices/",
   elementFormDefault = XmlNsForm.QUALIFIED
)
package com.starlims.webservices;

Javabean属性名称传统上是小写的。您的WSDL中有一个大写的标记名称，即ProcessUIRequestResult，但是类中的小写属性processUIRequestResult，由方法名称setProcessUIRequestResult和getProcessUIRequestResult隐含。

Java代码生成的WSDL似乎是正确的，但并不意味着其他库代码尊重WSDL和/或Java注释。

你能用小写元素名称吗？
