Sending JWT Token in the body of response Java Spring

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
