pw-iso20022解析工具自定义报文标签前缀＜pacs:document＞

public class test{ 
  private static final Map<String, JAXBContext> contextCache = new ConcurrentHashMap<>();

 private void testXml(String xml) {
    AbstractMX msg = getAbstractMX(xml, (Class)MxCamt00200102.class, new Class[] {MxCamt00200102.class, BusinessAppHdrV02.class });

    xml = "<message>" + xml + "</message>";
    Class<?>[] classes = new Class[] { MxCamt00200102.class
    //可根据需要设置多个消息类
 };
    try {
      JAXBContext jaxbContext = getJAXBContext(targetClass.getName(), classesToBeBound);
      Marshaller marshaller = jaxbContext.createMarshaller();
      marshaller.setProperty("jaxb.encoding", "UTF-8");
      marshaller.setProperty("jaxb.formatted.output", Boolean.valueOf(true));
      marshaller.setProperty("jaxb.fragment", Boolean.valueOf(false));
      marshaller.setProperty("com.sun.xml.bind.namespacePrefixMapper", new NamespacePrefixMapper() {
            public String getPreferredPrefix(String namespaceuri, String suggestion, boolean requirePrefix) {
              if (namespaceuri.equals("urn:iso:std:iso:20022:tech:xsd:pacs.002.001.02"))
                return "pacs"; 
              
              if (namespaceuri.equals("urn:iso:std:iso:20022:tech:xsd:head.001.001.02"))

      MxReadParams mxReadParams = new MxReadParams(new MxReadConfiguration(new MxWriteConfiguration(jaxbContext)));

      return abstractMX;
    } catch (JAXBException e) {

      return null;
    } 
  }

private static JAXBContext getJAXBContext(String packageName, Class... classesToBeBound) throws JAXBException {
    JAXBContext jaxbContext = contextCache.get(packageName);
    if (jaxbContext == null) {
      log.debug("Creating new JAXBContext instance for package: " + packageName);
      jaxbContext = JAXBContext.newInstance(classesToBeBound);
      contextCache.put(packageName, jaxbContext);
    } 
    return jaxbContext;
  }

}

根据解析报文消息类，可以根据需求自定义标签。当然在添加多个消息类时，依然需要通过报文类型去校验。通过if条件进行区分。我也通过AI去搜集过更通用，更便捷的解析方式，想要减少非必要的重复性代码编写。奈何本人技术有限，暂时还没有找到更便捷的方式。哪位大神若是看到了，还请指点一二。
