不做特殊处理，openfeign 不能反序列化对方返回的数据，如果response header是text/plain or text/json的话。通常会出现 Could not extract response: no suitable HttpMessageConverter found for response type [cn.justme.sboot.entity.BaseResp<java.lang.String>] and content type [text/plain;charset=UTF-8]

解决方法如下：
全局修改，使所有的调用都支持TEXT_PLAIN的Content-Type

@Configuration
public class FeignConfig {
    /**
     * 处理 no suitable HttpMessageConverter found for response [text/plain;charset=UTF-8]
     */
    @Bean
    public MappingJackson2HttpMessageConverter customMappingJackson2HttpMessageConverter() {
        return new CustomMappingJackson2HttpMessageConverter();
    }
    static class CustomMappingJackson2HttpMessageConverter extends MappingJackson2HttpMessageConverter {
        public CustomMappingJackson2HttpMessageConverter() {
            setSupportedMediaTypes(Collections.singletonList(MediaType.TEXT_PLAIN));
        }
    }
}
