1. Current request is not a multipart request

feign接口参数使用@RequestPart 而非@RequestParam, 同时需要指定consumes,比如这样：

@PostMapping(value="/upload",consumes= MediaType.MULTIPART_FORM_DATA_VALUE)
    Result<FileStorage>upload(@RequestPart(value="file") MultipartFile file);

2. Feign failed and no fallback

这是hystrix导致，关闭feign熔断，或者延长熔断的超时时间,我简单粗暴的直接关了

3.Read timed out executing POST for “xxx”

配置了hystrix还不行，或者延长ribbon的超时时间，参考了Feign超时问题的办法，简单来说就是feign经过了ribbonn和hystrix两级调用，而且都有一个默认的超时时间，延长超时时间就好了
