Sending JWT Token in the body of response Java Spring

Question

I send the token of JWT in Header, but the client need it in the body of the response, how can I put it in the response :

 @Override protected void successfulAuthentication( HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult) throws IOException, ServletException {
  User springUser = (User) authResult.getPrincipal(); String jwt = Jwts.builder() .setSubject(springUser.getUsername()) .setExpiration(new Date(System.currentTimeMillis()+SecurityConstants.EXPIRATION_TIME)) .signWith(SignatureAlgorithm.HS256, SecurityConstants.SECRET) .claim("roles",springUser.getAuthorities()) .compact(); response.addHeader(SecurityConstants.HEADER_STRING, SecurityConstants.TOKEN_PREFIX+jwt); }

I need to put the token in the response

If I understand you properly you just need to create a response body

response.setContentType("application/json"); response.setCharacterEncoding("UTF-8"); response.getWriter().write( "{\"" + SecurityConstants.HEADER_STRING + "\":\"" + SecurityConstants.TOKEN_PREFIX+jwt + "\"}" );

Take a look at How do you return a JSON object from a Java Servlet

This response have opened my eyes... after a long researching with no success, finally I've got this solution and it worked fine for me. I needed to return the token in my response body and this is what I did (following this solution). Thank you very much
