问题描述

在springboot 2的版本中通过feign进行调用，在引入私服jar包并进行调用时，报错：

feign.codec.DecodeException: Could not extract response: no suitable HttpMessageConverter found for response type [xxx.Response<com.xxx.XxxResponseDto>] and content type [application/octet-stream;charset=utf-8]

其中，Response是返回报文实体类，XxxResponseDto是返回报文中的响应体（body部分），返回报文分为head和body两部分，如下

{"head": {"retFlag": "00000","retMsg": "成功"},"body": {"data": {// 报文数据}}
}

分析原因

暂无

解决方法

首先，调用时在请求头header中添加Content-Type = application/json，不行！

其次，像下边的代码一样添加consumes和produces属性

@FeignClient(name = "服务实例名")
public interface XxxClient {@PostMapping(value = "/x/x/x/x", consumes = "application/json;charset=utf-8", produces = "application/json;charset=utf-8")Response<XxxResponseDto> getXXX(@Valid @RequestBody XxxRequestDto requestDto);
}

在加上之后还是不行！

后来，直接用postman调用url为“/x/x/x/x”的接口，发现调不通了，在解决单独调接口调不通这个问题后，再次通过之前的方式调用，可以调通了。
