error info: feign.codec.DecodeException: Could not extract response: no suitable HttpMessageConverte

使用feign框架的@FeignClient调用GET请求，并接受json返回值的时候，会报Could not extract response: no suitable HttpMessageConverte 异常, 需要在fastMediaTypes添加fastMediaTypes.add(MediaType.TEXT_PLAIN);配置

List<MediaType> fastMediaTypes = new ArrayList<MediaType>();

fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
fastMediaTypes.add(MediaType.TEXT_PLAIN);

fastJsonHttpMessageConverter.setSupportedMediaTypes(fastMediaTypes);
