java - CXF SOAP 服务保留空间

Question

我有 CXF SOAP 网络服务。

@Component
@WebService(endpointInterface = "com....MyWs", serviceName="MySrv")
public class MyWsImpl implements MyWs {
    @Override
    public List<MyModel> get(String customer) {
        List<MyModel> models = ...;
        return models;
    }
}

MyModel 中有一个字段可以是空格 ( " " )，但解析器会修剪该值并将其序列化为 <mySpaceVal></mySpaceVal>我想要 <mySpaceVal> </mySpaceVal>

我该怎么做？

我尝试添加

@XmlAttribute(name="space", namespace="xml")
public final static String space = "preserve";

到 MyModel 以便解析器可以添加 xml:space="preserve"属性。但它添加了一个命名空间 ns3="xml"并将属性显示为 ns3:space="preserve"并且该元素显示为空字符串而不是 " "

您可以将字符串值包装在 <![CDATA[]]> 中使用 jaxb 的部分适配器:

@XmlJavaTypeAdapter(CDATAXmlAdapter.class)
public final static String space = "...";

private static class CDATAXmlAdapter extends XmlAdapter<String, String> {
    @Override
    public String marshal(final String value) throws Exception {
        // you may want to apply additional value escaping to avoid
        // CDATA nesting problem
        return "<![CDATA[" + value + "]]>";
    }

    @Override
    public String unmarshal(final String value) throws Exception {
        // If you expect that server will send CDATA as well
        // then you need to strip CDATA from value
        return value;
    }
}
