java - WebSphere 8.5.5.3 中的 JAXB 编码导致 SOAP 响应 XML 中的接口(interface)元素

Question

我们有一个 Web 服务，它使用 JAXB 来编码和解码 SOAP 请求和响应。我们在 Tomcat 上使用 Sun/Oracle JDK7，在 WebSphere 8.5.5.3 上使用相应的 IBM JDK7。该应用程序在 Tomcat 上按预期运行，但是由于该类在响应 XML 中实现的 Java 接口(interface)的额外元素，来自 WebSphere 的解码响应导致空对象。 示例 Java 动态 Web 服务项目是在 Eclipse (Kepler Service Release 2) 中创建的，用于在返回扩展抽象类的类时重现对象编码错误，该抽象类返回 WebSphere 中的接口(interface)。该项目的结构如下:

• Person.java - Person 是一个接口(interface)。
• Employee.java - Employee 是一个实现 Person 接口(interface)的类。

• Manager.java - Manager 是一个扩展 Employee 类的类。

• Department.java - 这是一个包含抽象方法 getPerson() 的抽象类，该方法返回一个 Person 接口(interface)。

• Finance.java - [这是一个扩展 Department 的类，它变形了一个 getPerson() 方法以返回一个 Manager 对象。]

• PersonnelEndPoint.java - [这是 Personnel Web 服务的一个端点，它包含一个返回财务对象的方法 getFinanceDepartment()]

注意有一个额外的元素 <person>在下面从 WebSphere 返回的 XML 中。 WebSphere 中是否有禁止从基本接口(interface)返回元素的选项？

从部署在 Tomcat 中的应用程序捕获的 SoapUI 如下:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <ns3:getFinanceDepartmentResponse xmlns:ppl="http://personnel.corporate.org" xmlns:ns3="http://application.corporate.org/">
         <return>
            <manager>
               <firstName>Austin</firstName>
               <internalId>1000</internalId>
               <lastName>Smith</lastName>
               <middleName>J</middleName>
               <level>1</level>
               <managerYn>true</managerYn>
            </manager>
         </return>
      </ns3:getFinanceDepartmentResponse>
   </S:Body>
</S:Envelope>

WebSphere 的结果如下:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <ns2:getFinanceDepartmentResponse xmlns:ppl="http://personnel.corporate.org" xmlns:ns2="http://application.corporate.org/">
         <return>
            <manager>
               <firstName>Austin</firstName>
               <internalId>1000</internalId>
               <lastName>Smith</lastName>
               <middleName>J</middleName>
               <level>1</level>
               <managerYn>true</managerYn>
            </manager>
            <person>
               <firstName>Austin</firstName>
               <internalId>1000</internalId>
               <lastName>Smith</lastName>
               <middleName>J</middleName>
               <level>1</level>
               <managerYn>true</managerYn>
            </person>
         </return>
      </ns2:getFinanceDepartmentResponse>
   </soapenv:Body>
</soapenv:Envelope>

Answer 1

我在 WASv8009 上试过你的代码，但没有成功。 Tomcat 和 WebSphere 处理 Web 服务的方式可能有所不同，但您的 Finance 类将返回 2 个复杂类型。 org.corporate.application.jaxws 在 WAS 中什么都不做。要实现您想要的效果，请将 @XmlAccessorType(XmlAccessType.FIELD) 添加到 Finance 类。
