Lo anterior es la clase de entidad convertida en XML, la relación correspondiente

El código de la clave de conversión es:

// Solicitar mayúsculas de la primera letra

xmlMapper.setPropertyNamingStrategy(UPPER_CAMEL_CASE);

//Encabezado de solicitud <?xml version='1.0' encoding='UTF-8'?>

xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, verdadero)

// solicitud de salida formateada, escritorConDefaultPrettyPrinter()

xmlMapper.writerWithDefaultPrettyPrinter().writeValueAsString(prueba);

 private static String printXml(XmlService test) {
        XmlMapper xmlMapper = new XmlMapper();
        xmlMapper.setPropertyNamingStrategy(UPPER_CAMEL_CASE);
        xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);
        // 格式化输出
        String xmlStr = null;
        try {
            xmlStr = xmlMapper.writerWithDefaultPrettyPrinter().writeValueAsString(test);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
        log.info("定制xml格式化输出：\n{}", xmlStr);
        return xmlStr;
    }

Esto es para analizar el XML para obtener los datos correspondientes dentro

    xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
