Spring security jwt 在successhandler中创建token报错

问题遇到的现象和发生背景

问题相关代码，请勿粘贴截图

   public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
        logger.info("登录成功");
        httpServletResponse.setContentType("application/json;charset=utf-8");
        Object user = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
        logger.info("user: "+user);
        String token = TokenUtil.createToken(user);
        RespBean respBean = RespBean.success("登录成功", user);
        httpServletResponse.setHeader("token", token);
        ObjectMapper om = new ObjectMapper();
        PrintWriter out = httpServletResponse.getWriter();
        out.write(om.writeValueAsString(respBean));
        out.flush();
        out.close();
    }

运行结果及报错内容

我的解答思路和尝试过的方法

我想要达到的结果

TokenUtil.createToken里面的user转json有问题把，signWith中的Base64Codec.decode
