Jackson adds backslash in json

Question

I\'m building REST service on Jersey and using Jackson to produce JSON from java classes of my model. Model with absolutely simple values, I think

Answer 1

I don't know why, but in my case it works doing this :

private static final String COOKIE_TEMPLATE = "{0}={1};Version={2};Domain={3};Max-Age={4};Path='/'";

response.addHeader("Set-Cookie", MessageFormat.format(COOKIE_TEMPLATE, cookie.getName(),cookie.getValue(), cookie.getVersion(), cookie.getDomain(),Integer.toString(cookie.getMaxAge())));
return ResponseEntity.ok(...);

cookie is a javax.servlet.http.Cookie, and cookie.getValue() contains a string produced by

ObjectMapper mapper = new ObjectMapper();
return mapper.writeValueAsString(obj);

If I use

response.addCookie(cookie)

I have a resulting cookie definition as JSON with backslashes.

But, if I use

response.addHeader("Set-Cookie",MessageFormat(TEMPLATE,cookie.get...))

I managed the same resulting cookie definition as JSON, but without backslashes.

In case of having several cookies, addHeader("Set-Cookie") only creates/updates the desired cookie. The other ones are maintained and won't be altered.
