标签: java spring-boot multipartform-data

我正在使用@RequestPart注释上载一些参数和一个图像文件。

但是我遇到了错误

Content type 'image/jpeg' not supported for bodyType=org.springframework.web.multipart.MultipartFile

下面是我的代码段。如果我在触发HTTP POST请求时跳过了文件部分。一切正常。

仅在传递文件期间。我得到了错误。

@PostMapping(value = "document/uploadFile", consumes = {"multipart/form-data"})
public void  uploadFile(@RequestPart(value = "name", required = true) String name,
                        @RequestPart(value = "fileType", required = true) String fileType,
                        @RequestPart(value = "file",required = false) MultipartFile file) 
                        {
                            ..logic to pick the data using POJO
                        }

application.yaml

## MULTIPART (MultipartProperties)
# Enable multipart uploads

    multipart:
      enabled: true
      # Threshold after which files are written to disk.

      # Max file size.
      max-file-size: 10MB
      # Max Request Size
      max-request-size : 20MB

我怀疑这是问题所在,但您最后在这里缺少括号 consums = {“ multipart / form-data”}

无论如何使用您当前的代码,它都可以正常工作,我进行了本地测试,因此您的问题可能出在如何执行请求上。

请确保将其添加为其余客户端中的RequestHeader: Content-Type:multipart / form-data ,或者如果您使用的是表单,则需要这样添加:< / p>

<form method="POST" action="/upload" enctype="multipart/form-data">
  <input type="file" name="file"/> 
  <input type="name" name="name"/> 
  <input type="fileType" name="fileType"/> 
  <button type="submit">Submit</button>
</form>
