스프링 부트 1.5 : 파일 업로드시 "multipart/*"허용

Question

My Spring Boot 1.5.1 + Commons Fileupload 1.3.2 파일 업로드 요청 매핑이 multipart/form-data과 함께 실패합니다. 이 같은 내 요청 매핑 모습하십시오 curl와

@RequestMapping(method=RequestMethod.POST, value="/api/users/uploads") 
public @ResponseBody ResponseEntity<?> uploadUsers(
    @RequestParam(value="file", required=true) MultipartFile file 
    ) throws IOException { 
    String uploadFilename = file.getName(); 

    try(InputStream input = file.getInputStream()) { 
     usersConverter.read(input); 
    } 

    return ResponseEntity.ok("Uploaded " + uploadFilename + " successfully."); 
} 

:

* Trying ::1... 
* Connected to localhost (::1) port 8080 (#0) 
* Server auth using Basic with user 'username'

하지만 대신 multipart/mixed의 multipart/form-data을 보내 일부 클라이언트가 내가 좋겠 :

curl -v -u 'username:password' 
    -H "Content-Type: multipart/mixed" 
    -X POST -F file=@users.csv 
    http://localhost:8080/api/users/uploads 

잘 작동합니다 이 요청 매핑과 같이 두 가지를 모두 처리 할 수 ​​있습니다.

• consumes="multipart/*"
• consumes={"multipart/mixed", "multipart/form-data"
• headers="content-type=multipart/*"
• headers={"content-type=multipart/mixed", "content-type=multipart/form-data"}

을하지만, 각각의 경우에 : 나는 추가 해봤하여 @RequestMapping에 다음

curl -v -u 'username:password' 
    -H "Content-Type: multipart/form-data" 
    -X POST -F file=@users.csv 
    http://localhost:8080/api/users/uploads 

는 400 실패 : multipart/form-data를 전송

* Connected to localhost (::1) port 8080 (#0) 
* Server auth using Basic with user 'username'

내 각도 2.4 클라이언트는 (아마도 같은) 400와 함께 실패합니다.

어떻게하면 multipart/form-data을 처리 할 요청 매핑을 얻을 수 있습니까?

Answer 1

어 - 그게 문제 야.

<!-- 
    <dependency> 
    <groupId>commons-fileupload</groupId> 
    <artifactId>commons-fileupload</artifactId> 
    <version>1.3.2</version> 
    </dependency> 

    <dependency> 
    <groupId>commons-io</groupId> 
    <artifactId>commons-io</artifactId> 
    <version>2.4</version> 
    </dependency> 
    --> 

및 multipartResolver 빈 정의를 제거 : commons-fileupload 및 commons-io 종속성을 제거

/* 
    @Bean(name = "multipartResolver") 
    public CommonsMultipartResolver multipartResolver() { 
     CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(); 
     multipartResolver.setMaxUploadSize(100000); 

     return multipartResolver; 
    } 
    */ 

는 요청 매핑은 multipart/mixed 예상대로 multipart/form-data 모두 작동 ... 내 각도 클라이언트도 작동합니다.
