@Override
public void write(T body, HttpRequestMessage httpRequestMessage) throws RestifyHttpMessageWriteException {
    try {/*from ww  w  . j a v  a 2  s. c  o  m*/
        JsonEncoding encoding = Arrays.stream(JsonEncoding.values())
                .filter(e -> e.getJavaName().equals(httpRequestMessage.charset())).findFirst()
                .orElse(JsonEncoding.UTF8);

        JsonGenerator generator = objectMapper.getFactory().createGenerator(httpRequestMessage.output(),
                encoding);

        objectMapper.writeValue(generator, body);
        generator.flush();

    } catch (IOException e) {
