knife4j的3.0.3版本文件上传不显示上传按钮【已解决】

使用SpringBoot3集成3.0.3版本knife4j之后的文件上传一直不显示上传按钮,经过不断尝试终于解决

这是原来的代码

@PostMapping("/upload")
@OptLog(optCode = OptCode.ADD, optDesc = "上传文件")
@Operation(summary = "上传文件")
public CommonResult<FileInfoUploadVO> uploadFileInfo(@RequestParam(value= "file") MultipartFile file) throws IOException {
    FileInfoUploadVO uploadVO = fileInfoService.saveFileInfo(file);
    return CommonResult.buildSuccess(uploadVO);
}

解决办法

将file的 @RequestParam 更换为 @RequestPart 即可,如下

@PostMapping("/upload")
@OptLog(optCode = OptCode.ADD, optDesc = "上传文件")
@Operation(summary = "上传文件")
public CommonResult<FileInfoUploadVO> uploadFileInfo(@RequestPart(value= "file") MultipartFile file) throws IOException {
    FileInfoUploadVO uploadVO = fileInfoService.saveFileInfo(file);
    return CommonResult.buildSuccess(uploadVO);
}
