拦截器返回false时，设置返回的body

最近写了一个demo，方便大家练习jmeter压测脚本以及接口自动化

其中一个功能是商品管理，需要拦截器鉴权token，如果失败返回false，此时要设置返回的body

 

拦截器中

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        String jsonBody = new BodyReaderHttpServletRequestWrapper(request).getBodyString(request);
        UserReq reqParam = JSONObject.toJavaObject(JSONObject.parseObject(jsonBody), UserReq.class);

        // 校验是否具备权限
        String token = reqParam.getToken();
        if (token==null || token.isEmpty()){
            ResultMsg fail = ResultMsg.fail(ResultCode.FAIL_TOKEN_NULL);
            preHandleFalseResponseJsonBody(fail, response);
            return false;
        } else if (redisUtil.exists(token)){
            // 续时
            redisUtil.expire(token, 600);
            return true;
        } else {
            ResultMsg fail = ResultMsg.fail(ResultCode.FAIL_TOKEN_EXPIRE);
            preHandleFalseResponseJsonBody(fail, response);
            return false;
        }
    }

 

设置返回json内容的方法

    private void preHandleFalseResponseJsonBody(ResultMsg resultMsg,HttpServletResponse response) throws Exception {
        response.setContentType("application/json; charset=utf-8");
        PrintWriter writer = response.getWriter();
        String s = JSONObject.toJSONString(resultMsg);
        writer.print(s);
        writer.close();
        response.flushBuffer();
    }
