## 1、报错信息 ##

由于报错 提示信息太长，所以只截取了一部分，不影响判断，原因是因为数据传输格式选择错误。

## 2、访问的Controller ##

@ApiOperation("添加广告")
    @ApiImplicitParam(name = "advertInfoParam",value = "添加广告" , dataType = "AdvertInfoParam", paramType = "body")
    @PostMapping("/advert/insertAdvert")
    public CommResponse<?> insertAdvert(@RequestHeader("accessToken") String accessToken,
                                        @RequestBody AdvertInfoParam advertInfoParam) {
         return this.advertInfoServiceFacade.insertAdvert(advertInfoParam);
    }

## 3、解决方案 ##

1、POSTMAN测试工具，原因是因为数据传输格式选择错误。

postman之所以报Unsupported Media Type: Content type 'text/plain;charset=UTF-8' not supported错误，是发送数据的格式不正确，需要修改数据的发送方式所匹配的格式。因为发送的数据是json格式的，而postman默认是text格式，有些会报错，所以改成选择json样式。

2、配置HTTP信息头管理器，增加消息头 Content-Type：application/json;charset=UTF-8
