Question

我在标头中发送JWT的令牌，但客户需要在响应主体中使用它，我怎样才能把它放在响应中：

    @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);
    }

我需要将令牌放入响应中

如果我对您的理解正确，那么您只需创建一个响应正文

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