I need to write an application which would be able to process binary data sent by CUrl, such as:

```
curl localhost:8080/data --data-binary @ZYSF15A46K1.txt

```

I've created a POST processing method as follows:

```
@RequestMapping(method = RequestMethod.POST, value = "/data")
    public void acceptData(HttpEntity<byte[]> requestEntity) throws Exception {
        process(requestEntity.getBody());
    }

```

However it doesn't seem to be returning raw binary data. I've tried sending a GZip file and after going through Spring it is now longer decompressible, which leads me to believe I'm either getting too much data or too little data.

How do I solve this issue and get raw binary data?
