Because spring converts byte [] to decimal string in JSON view

Question

public class Profile {
private String profId;
private byte[] image;
....
}

I debugged and everything is fine till I return the mav ( it has the byte array[])

[-119, 80, 78, 71, 13, 10, -26, 10, 0, 0, 0, 13, 73, 72, 68,...,46,89]

But when I checked the JSON response on browser it got string instead of array

{
"prof": {
      "profId": "Test123",
      "image": "-1198078711310-261000013737268...4689",
      "cretDt": "06-19-2013 12:16:25",
      "state": 6002,
      "stateName": "Approved"
    }
}

Join the byte.

Can some one help me hot to get the byte[] or encoded in Base64 again on my browser.
