If you use The RestTemplate in the spring framework must set the encoding character set to UTF-8, because its default is 8859-1 My God, I am about to crash
private static RestTemplate template = new RestTemplate();

static{
List<HttpMessageConverter<? >> converterList=template.getMessageConverters();
        HttpMessageConverter<?> converterTarget = null;
        for (HttpMessageConverter<?> item : converterList) {
            if (item.getClass() == StringHttpMessageConverter.class) {
                converterTarget = item;
                break;
            }
        }

        if (converterTarget != null) {
            converterList.remove(converterTarget);
        }
        HttpMessageConverter<?> converter = new StringHttpMessageConverter(Charset.forName("UTF-8"));
        converterList.add(converter);
}
