序列化对象并从Web Java下载

发布于 2025-02-14 01:01:33 字数 1251 浏览 4 评论 0原文

我有一个项目（Spring Boot，MVC），其中：

1。单击按钮时，应打开窗口，用户选择路径，并应将新创建的文件导出到那里用户的计算机。该文件是使用对象序列化创建的。

2。和另一个按钮以相反的顺序：文件导入，避免，对象获取。

我知道这是通过此形式解决的，但是我无法确切地弄清楚如何解决。

<form id="singleUploadForm" name="singleUploadForm">
     <input id="singleFileUploadInput" type="file" name="file" class="file-input" required />
     <button type="submit" class="primary submit-btn">Submit</button>
</form>

用静态保存路径序列化对象的示例：

SavedGame savedGame = new SavedGame(info1, info2, info3);

FileOutputStream outputStream = new FileOutputStream("C:\\Users\\Username\\Desktop\\save.ser");
ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream);

objectOutputStream.writeObject(savedGame);

objectOutputStream.close();

我在Internet上没有找到解决此特定问题的解决方案，我只找到了很多此类教程 https://www.callicoder.com/spring-boot-file-upload-download-download-rest-api-example/ ，这不能直接解决我的问题。具体来说，我不明白在哪里插入我的序列化文件。

问题：是否有有关灭菌的明确教程或视频，然后是从网络中保存的？

我会为任何帮助感到高兴！我已经解决问题了一个星期...

原文

I have a project (Spring Boot, MVC) where:

1. When the button is clicked, a window should open in which the user selects a path, and a newly created file should be exported there to the user's computer. The file is created using object serialization.

2. And in reverse order by another button: file import, deserialization, object acquisition.

I know that this is solved by this form, but I can't figure out exactly how.

<form id="singleUploadForm" name="singleUploadForm">
     <input id="singleFileUploadInput" type="file" name="file" class="file-input" required />
     <button type="submit" class="primary submit-btn">Submit</button>
</form>

Example of serializing my object with a static save path:

SavedGame savedGame = new SavedGame(info1, info2, info3);

FileOutputStream outputStream = new FileOutputStream("C:\\Users\\Username\\Desktop\\save.ser");
ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream);

objectOutputStream.writeObject(savedGame);

objectOutputStream.close();

I didn't find a solution to this particular problem on the Internet, I only found a lot of such tutorials https://www.callicoder.com/spring-boot-file-upload-download-rest-api-example/ which don't solve my problem directly. Specifically in this I do not understand where to insert my serialized file.

The question: is there any clear tutorial or video on sterilization followed by saving from the web?

I will be very glad of any help! I've been solving the problem for a week now...
