记录一次HttpServletRequest无法获取请求参数问题

request.getInputstream和request.getReader都无法获取参数
使用如下方法可以

 ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();

        // 获取请求入参
        String requestBody = null;
        ContentCachingRequestWrapper wrapper = WebUtils.getNativeRequest(request, ContentCachingRequestWrapper.class);
        if (wrapper != null) {
            byte[] buf = wrapper.getContentAsByteArray();
            if (buf.length > 0) {
                requestBody = new String(buf, 0, buf.length, wrapper.getCharacterEncoding());
            }
        }```
