Tomcat：WebService 响应为 zip 存档而不是文件

发布于 2024-10-13 20:43:35 字数 687 浏览 2 评论 0原文

我希望网络服务以 zip 文件形式做出响应。

一般来说，没有什么难做的事情。但我想知道一件事：即使文件很大（100Mb - 500Mb），我可以压缩文件而不将其保存到硬盘吗？

现在我正在使用这个不错的技巧。我想通过压缩功能来扩展它，而不在文件系统上创建新文件。

public class TempFileInputStream extends FileInputStream {

    private File file;

    public TempFileInputStream(File file) throws FileNotFoundException {
        super(file); // TO WANT: to pass here already zipped stream
        this.file = file;
    }

    @Override
    public void close() throws IOException {
        super.close();
        if (!file.delete()) {
            // baad
        } else {
            // good 
        }
    }
}

如果可以，那么更好/最佳的方法是什么？

感谢您的帮助！

I want web service to make response as a zip file.

Generally there is nothing hard to do. But there is one thing I want to know:
Can I zip file without saving it to the hard disk, even if it's very large (100Mb - 500Mb)?

Now I'm using this nice hack. And i want to extend it with ziping functionality without creating new files on the file system.

public class TempFileInputStream extends FileInputStream {

    private File file;

    public TempFileInputStream(File file) throws FileNotFoundException {
        super(file); // TO WANT: to pass here already zipped stream
        this.file = file;
    }

    @Override
    public void close() throws IOException {
        super.close();
        if (!file.delete()) {
            // baad
        } else {
            // good 
        }
    }
}

If I can, then what is the better/optimal way to do it ?

Thanks for any help !
