Question

在旧的java 1.5 webservice中，响应消息是从包含XML的String构造的，在将Web服务迁移到java 7时，这似乎不再正常工作。因此，我使用现有的HL7 WSDL生成类，以便创建一个java对象模型，该模型将使用Jaxb映射到XML。所以，根据旧的webservice，在acknowledgementDetail中，标签应该出现，如下所示：

<acknowledgement typeCode="CE">
        <acknowledgementDetail typeCode="E">
           <text>Some text</text>
        </acknowledgementDetail>
</acknowledgement>

但是，生成的acknowledgementDetail类的方法setText（）只接受org.hl7.v3.ED类型或其子类的对象。

生成的ED类只有一个相关方法：可通过ed.getAny（）

访问的元素列表（List）

ED ed = new ED();
ed.getAny().add(document.getDocumentElement());
acknowledgementDetail.setText(ed);
acknowledgement.getAcknowledgementDetail().add(acknowledgementDetail);

我创建了上面的“文档”：

DocumentBuilder documentBuilder;
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();

try {
     documentBuilder = documentBuilderFactory.newDocumentBuilder();
     document = documentBuilder.newDocument();                           
     Node node = document.createElement("dummy");
     node.setTextContent("Some text");                             
     document.appendChild(node);                
} catch (ParserConfigurationException e) {
    sLog.error("ParserConfigurationException: ", e);
}

对我来说，这对于一个字符串来说似乎是一项非常多的工作，但除了这一点之外......

当我创建一个org.w3c.dom.Element时，我被迫给Element一个名字（在这种情况下为“dummy”），否则Jaxb会因异常而失败。我一直得到的结果是这样的：

<acknowledgement typeCode="CE">
    <acknowledgementDetail typeCode="E">
        <text>
            <dummy xmlns="">Some text</dummy>
        </text>
    </acknowledgementDetail>
</acknowledgement>

在ED类的文档中，它表示子类ST应该用于文本，因此将类型ED更改为ST类型并添加：

st.setRepresentation(CsBinaryDataEncoding.TXT);

导致以下结果：

<acknowledgement typeCode="CE">
    <acknowledgementDetail typeCode="E">
        <text representation="TXT" xsi:type="ST">
            <dummy xmlns="">Some text</dummy>
        </text>
     </acknowledgementDetail>
</acknowledgement>

......这显然无法解决我的问题：S

我不明白，如何在元素中获得纯文本？！？欢迎任何建议，这需要尽快完成并尽快工作，所以任何可能的解决方案都会受到欢迎！

Answer 1

我最终使用生成的acknowledgementDetail的setText方法来接受字符串而不是ED。这当然非常难看，但是在编组输出XML时似乎工作得很好，而且我再也找不到合适的解决方案了。

使用生成的HL7类创建纯文本元素
