"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There are two ways you can do it. a) use a ResponseExtractor, and b) read the whole response as byte [].

If you want to use a byte [] :

ResponseEntity<byte[]> response = restTemplate.build()
                                                         .exchange("<URL TO ZIP FILE>", HttpMethod.GET, entity, byte[].class);
           Files.write(Paths.get("path to your local disk to save the zip"), response.getBody());

If you want to use a ResponseExtractor:

RequestCallback req= request -> request.getHeaders()
        .setAccept(Arrays.asList(MediaType.APPLICATION_OCTET_STREAM, MediaType.ALL));

ResponseExtractor<Void> re = response -> {
    Path path = Paths.get("path to file that you want to save");
    Files.copy(response.getBody(), path);
    return null;
};
restTemplate.execute(URI.create("URL of the zip file"), HttpMethod.GET, req, re);

Thanks a lot. This is what I was missing
headers.setAccept(Arrays.asList(MediaType.APPLICATION_OCTET_STREAM, MediaType.ALL)
I used headers.setContentType(MediaType.APPLICATION_OCTET_STREAM), instead, and wonder why it didn't  work.
Again thanks a lot.
