关于Spring RestTemplate乱码问题解决

StringHttpMessageConverter m = new StringHttpMessageConverter(Charset.forName("UTF-8"));
        RestTemplate restTemplateF = new RestTemplateBuilder().rootUri("https://console.tim.qq.com").additionalMessageConverters(m).build();
        HttpHeaders headers = new HttpHeaders();
        MediaType type = MediaType.parseMediaType("application/json; charset=UTF-8");
        headers.setContentType(type);
        headers.add("Accept", MediaType.APPLICATION_JSON.toString());

        String jsonStr = JSONObject.toJSONString(requestEntity);

        HttpEntity formEntity = new HttpEntity(jsonStr, headers);

        //应答
        String s = restTemplateF.postForObject(URI_splice_administrator_parameters(friend_get_all), formEntity, String.class);
