springcloud feign增加响应报文解码类型

feign 默认只支持application/json 类型的响应报文，如果响应的并非这种类型，则无法解析，此时需要自定义实现

案例如下：

package com.eno.config.feign;import java.util.ArrayList;
import java.util.List;import org.springframework.http.MediaType;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
/*** * @ClassName: FeignMessageConverter* @Description: 新增feign 消息解码类型支持*/
public class FeignMessageConverter extends MappingJackson2HttpMessageConverter {public FeignMessageConverter() {List<MediaType> mediaTypes = new ArrayList<>();mediaTypes.add(MediaType.TEXT_PLAIN);mediaTypes.add(MediaType.TEXT_HTML);setSupportedMediaTypes(mediaTypes);}
}

2.自定义实现decoder

@Beanpublic Decoder feignDecoder() {FeignMessageConverter converter = new FeignMessageConverter();ObjectFactory<HttpMessageConverters> objectFactory = () -> new HttpMessageConverters(converter);return new SpringDecoder(objectFactory);}
