Spring Boot Multipart文件与JSON数据一起上传

Question

我想使用Spring Boot Multipart文件上传作为json主体的一部分来编写api，也想将img url保存在数据库中。 看起来像这样的请求：

------WebKitFormBoundarynBsAcX7rJhOGsmfY
Content-Disposition: form-data; name="fdata"; filename="blob"
Content-Type: application/json

{"firstname":"saurabh","lastname":"mishra","mobile":"943847557"}
------WebKitFormBoundarynBsAcX7rJhOGsmfY
Content-Disposition: form-data; name="files"; filename="download.jpg"
Content-Type: image/jpeg


------WebKitFormBoundarynBsAcX7rJhOGsmfY--

请帮助我找到解决方案。

Answer 1

我以这种方式解决了这个问题。

我的API方法

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/singleFileUploadWithObject/{folder}",
        method = RequestMethod.POST)
@ResponseBody
public String singleFileUploadWithObject(
        @PathVariable(name="bucket-uuid", required = true) String bucketUUId,
        @PathVariable(name="folder", required = false) String folder,
        FileWithObject rawData) {
    return pingResponse;
}

我的FileWithObject DTO

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({ "file", "files", "data" })
public class FileWithObject<T> {

    @JsonProperty("file")
    private MultipartFile file;
    @JsonProperty("files")
    private MultipartFile[] files;
    @JsonRawValue
    @JsonProperty("data")
    private T data;
    // getter/setter and other...
}

注意：-对于数据参数，您可以在singleFileUploadWithObject方法中使用映射过程，希望对您和其他人有帮助
