访问Shiro接口返回trace问题

问题情景：
在使用Apache Shiro进行权限管理和认证时，返回一堆信息，如下

解决方案:

不希望异常信息中的trace被返回给前端或者用户，希望展示友好的错误信息而非详细的堆栈跟踪
可以在JwtFilter的preHandle加如下处理

 @Override
    protected boolean preHandle(ServletRequest servletRequest, ServletResponse response) throws Exception {
        HttpServletRequest httpRequest = WebUtils.toHttp(servletRequest);
        HttpServletResponse httpResponse = WebUtils.toHttp(response);
        if (httpRequest.getMethod().equals(RequestMethod.OPTIONS.name())) {
            httpResponse.setHeader("Access-Control-Allow-Credentials", "true");
            httpResponse.setHeader("Access-control-Allow-Origin", httpRequest.getHeader("Origin"));
            httpResponse.setHeader("Access-Control-Allow-Methods", "GET,PUT,DELETE,UPDATE,OPTIONS");
            httpResponse.setHeader("Access-Control-Allow-Headers", httpRequest.getHeader("Access-Control-Request-Headers"));

            System.out.println(httpRequest.getHeader("Origin"));
            System.out.println(httpRequest.getMethod());
            System.out.println(httpRequest.getHeader("Access-Control-Request-Headers"));
            httpResponse.setStatus(HttpStatus.OK.value());
            return false;
        }
        HttpServletRequest request = (HttpServletRequest) servletRequest;
        String token = request.getHeader("token");
        if (token != null) {
            try {
//                Map<String, Claim> claimMap = JwtUtils.verifyToken(token);
//                String authToken = claimMap.get("token").asString();
                JwtToken jwtToken = new JwtToken(token);
                Subject subject = SecurityUtils.getSubject();
                subject.login(jwtToken);
                return true;
            } catch (Exception e) {
                e.printStackTrace();
               response.getWriter().print(JSON.toJSONString(new Result<>().setCode(402).setMsg("token失效，请重新登录")));
            }
        }
        return false;
    }

效果如下
