Spring mvc SpringMVC:上传一个文件
我在用SpringMVC4.2.1上传文件时遇到一些问题 以下是端点的代码:Spring mvc SpringMVC:上传一个文件,spring-mvc,multipartform-data,Spring Mvc,Multipartform Data,我在用SpringMVC4.2.1上传文件时遇到一些问题 以下是端点的代码: @CrossOrigin @ApiOperation(value = "Add an attachment to a video", notes = "Add an attachment to the video with a specific id.", response = String.class) @ApiResponses(value = { @ApiResponse(code = 20
@CrossOrigin
@ApiOperation(value = "Add an attachment to a video", notes = "Add an attachment to the video with a specific id.", response = String.class)
@ApiResponses(value = {
@ApiResponse(code = 200, message = "Succesfully attached."),
@ApiResponse(code = 403, message = "Request could not be authorized."),
@ApiResponse(code = 500, message = "Internal Server Error."),
@ApiResponse(code = 400, message = "Malformed request.") })
@RequestMapping(value = "/attachment/add",
produces = { "application/json" },
consumes = { "multipart/form-data" },
method = RequestMethod.POST)
public ResponseEntity<String> addAttachmentVideo(@ApiParam(value = "ID of the document", required = true) @RequestParam(value = "docId", required = true) String docId,
@ApiParam(value = "file detail") @RequestPart("file") MultipartFile file,
@ApiParam(value = "Name of the attachment", required = true) @RequestParam(value = "attachmentName", required = true) String attachmentName)
throws NotFoundException {
VideoControllerMock dummyClass = new VideoControllerMock();
ResponseEntity<String> dummyResponse = dummyClass.addAttachmentVideo(docId, file, attachmentName);
return dummyResponse;
}
最后是函数getMultiPartHeaders
:
public HttpHeaders getMultiPartHeaders() {
HttpHeaders headers = new HttpHeaders();
//headers.add(CREDENTIALS_NAME, "true");
//headers.add(ORIGIN_NAME, "http://localhost:8080");
headers.add(METHODS_NAME, "GET, OPTIONS, POST, HEAD");
headers.add(HEADERS_NAME, "Origin, X-Requested-With, Content-Type, Accept");
headers.add(CONTENT_TYPE, "multipart/form-data");
headers.add(MAX_AGE_NAME, "3600");
return headers;
}
遗憾的是,我无法更改端点的代码。。它是由swagger codegen自动生成的。。但是我可以改变另外两个功能
如果使用此选项,则会出现以下错误:
[WARNING]
org.springframework.web.util.NestedServletException:
Request processing failed;
nested exception is java.lang.IllegalArgumentException:
Expected MultipartHttpServletRequest:
is a MultipartResolver configured?
有人知道如何解决这个问题吗??问题是我不知道如何配置这个多部分解析器
提前感谢您(在您的mvcconfig中)这样配置
CommonsMultipartResolver
:
你说的mvcconfig是什么意思??

@Bean
public CommonsMultipartResolver multipartResolver(){
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
multipartResolver.setDefaultEncoding("UTF-8");
multipartResolver.setMaxUploadSize(-1);
return multipartResolver;
}
