Answer 1

private String callViaRest(String requestString, Steps step) {
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.TEXT_XML);
    headers.add("Accept-Encoding", "application/gzip");
    HttpEntity entity = new HttpEntity(requestString, headers);

    byte[] responseBytes = jsonRestTemplate
            .exchange("yourUrl", HttpMethod.POST, entity, byte[].class).getBody();
    String decompressed = null;
    try {
        decompressed= new String(CompressionUtil.decompressGzipByteArray(responseBytes),Charsets.UTF_8);
    } catch (IOException e) {
        LOGGER.error("network call failed.", e);
    }
    return decompressed;
}
