SpringBoot微服务项目，一个微服务调用另一个微服务的feign传文件时报错。

Question

用postman测试一个接口，这个接口调用另一个微服务的feign接口上传文件时，出现
feign.codec.EncodeException: Type definition error: [simple type, class java.io.FileDescriptor]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class java.io.FileDescriptor and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: org.springframework.web.multipart.support.StandardMultipartHttpServletRequest$StandardMultipartFile["inputStream"]->java.io.FileInputStream["fd"])错误

然后在PostMapping处添加consumes = MediaType.MULTIPART_FORM_DATA_VALUE，又出现
feign.codec.EncodeException: Could not write request: no suitable HttpMessageConverter found for request type [org.springframework.web.multipart.support.StandardMultipartHttpServletRequest$StandardMultipartFile] and content type [multipart/form-data].
这个应该怎么解决？

Answer 1

feign需要加依赖才能传文件，其实用restTemplate也行
