客户端将一个JSON字符串传递给服务器,服务器将该字符串反序列化为一个Object,如下所示:
@PostMapping("/web/UploadVideo")
@ApiOperation("UploadVideo")
public Result uploadVideoWB(HttpServletRequest request,
@RequestParam("sourceFile") MultipartFile sourceFile,
@RequestParam("videoBean") String videoBean) {
Object object = request.getSession().getAttribute("UserId");
if (object == null) {
System.out.println("userId is null");
return new Result(false, "UserId is null", null, null);
} else {
System.out.println("1. " + videoBean);
VideoBean video = new Gson().fromJson(videoBean, VideoBean.class);
video.setVideoUser((String) object);
System.out.println("2. " + new Gson().toJson(video));
return videoService.uploadVideo(sourceFile, new Gson().toJson(video));
}
}
控制台输出如下所示:格式化它们:

}
您可以看到,originalFileName属性已消失!!!
VideoBean.class:
public class VideoBean {
private String objectId;
private String videoId;
private String sha1;
private long duration;
private String fileCategory;
private String originalFilename;
private String sourceFileName;
private String coverFileName;
private String thumbnailFileName;
private String blurFileName;
private String videoUser;
private int videoStatus;
private long createTime;
getter/setter ...
}
为什么?
我应该怎么做才能使反序列化正常?

您的
VideoBean
是错误的(您的类中的originalFilename
与JSON中的originalFileName
,请注意name
中的小写n
)。请使用以下代码:
