Spring HttpServletRequest is empty when already used

At Class A after getting the request body, The Class B is getting empty request body.As per checking if going to comment the code in Class A to retrieve the request body, Class B will able to get the request body.

Is there a way to make HttpServletRequest will not remove the request body in Class A, Inorder Class B can still get the request body?

Class A

@Autowired        private HttpServletRequest request; public Authentication authenticate(Authentication authentication) throws AuthenticationException { String requestBody =  extractBody(request);            System.out.println("Request Body1: "+requestBody);....other codes}   public static String extractBody(HttpServletRequest request){        String body = null;        StringBuilder stringBuilder = new StringBuilder();        BufferedReader bufferedReader = null;        try {            InputStream inputStream = request.getInputStream();            if (inputStream != null) {                bufferedReader = new BufferedReader(new InputStreamReader(inputStream));                char[] charBuffer = new char[128];                int bytesRead = -1;                while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {                    stringBuilder.append(charBuffer, 0, bytesRead);                }            } else {                stringBuilder.append("");            }        } catch (IOException ex) {            try {                throw ex;            } catch (IOException e) {                throw new RuntimeException(e);            }        } finally {            if (bufferedReader != null) {                try {                    bufferedReader.close();                } catch (IOException ex) {                    try {                        throw ex;                    } catch (IOException e) {                        throw new RuntimeException(e);                    }                }            }        }        body = stringBuilder.toString();        return body;    }
