SOAP 请求中不包含 JAX-WS Null 参数

Question

我的问题是，当通过 SOAP UI（JAX-WS 客户端）从 Java 生成的代码发送请求时，空参数包含在 SOAP 生成的请求中。

我正在从第三方 WSDL 生成soap客户端，所以对 WSDL 修改没有任何控制权。

来自 Java 生成客户端的消息，没有具有空值的参数。我必须有空元素，即<authId> & <reserved>

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Body>
        <BillPayment xmlns="http://action.one.worldnet.org">
        <userName>test</userName>
        <password>testing2</password>
        <AccountNumber>10385699</AccountNumber>
        <amount>0000000002300</amount>
        <tranDate>20130311</tranDate>
        <tranTime>064536</tranTime>
        <bankMnemonic>TIMEPAY</bankMnemonic>
        </BillPayment>
    </S:Body>
</S:Envelope>

来自 SOAPUI 的消息，其中包含值为 null 的元素。

<soap:Body>
    <soap:Envelope>"
      <act:BillPayment>
         <act:userName>test</act:userName>
         <act:password>testing2</act:password>
         <act:AccountNumber>9132388</act:AccountNumber>
         <act:authId></act:authId>
         <act:amount>0000000010000</act:amount>
         <act:tranDate>20130311</act:tranDate>
         <act:tranTime>172345</act:tranTime>
         <act:bankMnemonic>THIRDParty</act:bankMnemonic>
         <act:reserved></act:reserved>
      </act:BillPayment>
   </soap:Body>
</soap:Envelope>"

以下是我生成的 BillPayment 类

@XmlAccessorType(XmlAccessType.FIELD)

您没有发布您的 WSDL。我怀疑您的<authId> 在架构定义中有minOccurs=0。我不确定您是在进行自上而下还是自下而上的设计。如果您使用自顶向下，您可以简单地在 WSDL 模式定义部分添加minOccurs=1。如果您使用的是自底向上的设计方法，您可以在 Web 服务代码中使用以下注释

@XmlElement(nillable=true, required=true)
String authId;

请注意，此注释需要 Metro 2.0 (JAXB 2.2) 或更高版本。

基于 cmets 编辑：

如果您可以升级到 JDK 7，它应该包含 JAX-WS 2.2。但是，如果由于任何原因无法升级整个 JDK，您可以按照说明 here 使用名为 Endorsed Standards Override Mechanism 的功能，只需升级 jaxws-api.jar 和 jaxb-api.jar 文件即可。
