Example 1 with DataBuffer

use of org.springframework.core.io.buffer.DataBuffer in project spring-framework by spring-projects.

the class Jaxb2XmlEncoder method encode.

@Override

    try {
        DataBuffer buffer = dataBufferFactory.allocateBuffer(1024);
        OutputStream outputStream = buffer.asOutputStream();
        Class<?> clazz = ClassUtils.getUserClass(value);
        Marshaller marshaller = jaxbContexts.createMarshaller(clazz);
        marshaller.setProperty(Marshaller.JAXB_ENCODING, StandardCharsets.UTF_8.name());
        marshaller.marshal(value, outputStream);
        return Flux.just(buffer);
    } catch (JAXBException ex) {
        return Flux.error(ex);
    }
}
