利用目标观测站插入MySQL数据库
原标题:Use ObjectOutputStream to insert into a MySQL database

目前,我担任多功能游戏服务器。 目前,它拯救了每个参与者,将其作为一个序列化文件,我期望通过我的SQL将其转换为拯救所有东西,以便我也能在我的网站上查阅。

我很想知道的是,要写到序列化档案中,我使用目标OutputStream。 以下是我挽救档案的方法。

public static final void storeSerializableClass(Serializable o, File f)
        throws IOException {
    ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(f));
    out.writeObject(o);
    out.close();
}

因此,我不禁要问的是,我是如何做到这一点的,但还是拯救了库克,而不是序列化? 我在玩弄几个不同的事情,但我似乎无法找到这样做的坚实方法。

我也没有必要知道如何在 Java使用我的SQL,我知道,我只需要知道我如何利用目标OutputStream。

You can store it as a Blob and then deserialize it. There is an example here: http://www.mindfiresolutions.com/Store-Java-Class-Object-in-Database-754.php

另一种可能性是将档案作为文本储存。 这一切都取决于要求。
