Feign 传输 MultipartFile 的一些问题

File 转 MultipartFile

pom.xml

<!-- https://mvnrepository.com/artifact/org.springframework/spring-mock --><dependency><groupId>org.springframework</groupId><artifactId>spring-mock</artifactId><version>2.0.8</version></dependency>

publicstatic MultipartFilegetMultipartFile(String fileName, File file)throws IOException{returnnewMockMultipartFile(fileName, file.getName(), ContentType.APPLICATION_OCTET_STREAM.toString(),newFileInputStream(file));}

报错 Current request is not a multipart request、Content type ‘’ not supported

• @PostMapping设置 consumes = MediaType.MULTIPART_FORM_DATA_VALUE
• 使用@RequestPart()，不能使用@RequestParam()

@PostMapping(value="/upload", consumes= MediaType.MULTIPART_FORM_DATA_VALUE)
ResultBodyupload(@RequestPart(value="file") MultipartFile file);

报错 Required request part ‘file’ is not present
