RestTemplate中文乱码问题

@Configuration

        RestTemplate restTemplate = new RestTemplate(factory);
        // 支持中文编码
        setRestTemplateEncode(restTemplate);

        factory.setReadTimeout(5000);//ms

        return factory;
    }

    public void setRestTemplateEncode(RestTemplate restTemplate) {
        if (null == restTemplate || ObjectUtils.isEmpty(restTemplate.getMessageConverters())) {
            return;
        }

        List<HttpMessageConverter<?>> messageConverters = restTemplate.getMessageConverters();
        for (int i = 0; i < messageConverters.size(); i++) {

            }
        }
