[Solved] Feign upload file related configuration

The service structure is very simple, and consumers call the service of the service provider through Feign.
The provider has a file upload function. According to the interface document, the parameter type is File, which is placed in parallel with other parameters.

Key points: 1. Use @RequestPart annotations for File parameters at the routing layer; 2. Add consumes = MediaType.MULTIPART_FORM_DATA_VALUE instructions at the interface layer.

1. Routing layer

    @PostMapping(value = "/notify/upload")
    @ApiOperation("上传通知音")
    public String upload (
            AudioRecordScooperReq audioRecordScooperReq,
            @RequestPart("file") MultipartFile file) {
   
        audioRecordScooperReq.setToken(tokenValue);
        return audioRecordFeign.upload(audioRecordScooperReq, file);
    }

2. Feign interface layer

    // 上传通知音 -
    @PostMapping(value = "/scooper-record/data/notify/upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    String upload(@SpringQueryMap AudioRecordScooperReq audioRecordScooperReq,
                  @RequestBody() MultipartFile file);
