Prevent Jackson XML mapper from adding wstxns to namespaces

Question

When serialising objects to XML and specifying namespaces for properties using @JacksonXmlRootElement(namespace = \"http://...\") Jackson will append or prepen

Answer 1

This seems to be the missing piece. It allows you to set the prefix and namespace.

   static class NamespaceXmlFactory extends XmlFactory {

    private final String defaultNamespace;
    private final Map prefix2Namespace;

    public NamespaceXmlFactory(String defaultNamespace, Map prefix2Namespace) {
        this.defaultNamespace = Objects.requireNonNull(defaultNamespace);
        this.prefix2Namespace = Objects.requireNonNull(prefix2Namespace);
    }

    @Override
    protected XMLStreamWriter _createXmlWriter(IOContext ctxt, Writer w) throws IOException {
        XMLStreamWriter2 writer = (XMLStreamWriter2)super._createXmlWriter(ctxt, w);
        try {
            writer.setDefaultNamespace(defaultNamespace);
            writer.setPrefix("xsi", "http://www.w3.org/2001/XMLSchema-instance");
            for (Map.Entry e : prefix2Namespace.entrySet()) {
                writer.setPrefix(e.getKey(), e.getValue());
            }
        } catch (XMLStreamException e) {
            StaxUtil.throwAsGenerationException(e, null);
        }
        return writer;
    }
}

The only remaining issue I have is

    @JacksonXmlProperty(localName = "@xsi.type", isAttribute = true, namespace = "http://www.w3.org/2001/XMLSchema-instance")
@JsonProperty("@xsi.type")
private String type;

Creates the following output:

Still trying to resolve how to make it be xsi:type="networkObjectGroupDTO" instead.
