Question

All: I am facing a problem here, my app is composed by some jar files and some other files, they are all located in one directory. I am planning to implement an auto-update feature. When the app know there is a new version on the server, it will download a zip file to temp directory. After downloading, it will ask customer if he d like to install it. If yes, my app will exit and I need to unzip the zip file and overwrite all files in the original directory. Now I am wondering:

我怎么能够回避档案并 over灭目录? 创建文字(这意味着我需要书写视窗的批量和其他平台的批量)? a. 创建支薪阶层,以做到这一点?

在离开后,我怎么能开始这种描述/ava?

一旦完成这项工作,我如何删除安装装置? 在新版本何时开始时,将其保存在温床上并加以检查?

I know JWS is a good choice, but for reason "my boss denied", I can t use it.

Answer 1

可采取几种办法。由于你说申请是交叉格式,因此最好利用 Java进行更新。

You can create a small jar file which will handle the update process. It could be part of the initial application (with the assumption it won t be updated) or it could be part of the update package (then you can update it as well).

因此,您的申请书下载了纸浆,没有包装给临时目录,并开始更新,然后从中提取。更新者复制了旧的轮胎。

然而,我们最好不要重新发明轮.。考虑使用国际社:它提供了更多的特点,需要较少努力执行。必须有良好理由,以否定JWS。你们应该通过解释利用日本妇女论坛的好处来说服你们。

Since the app. has a GUI (judging by the Swing tag), deploy it using Java Web Start:

Java Webstart(JWS)是Oracle Corporation技术,用于直接从网络或互联网上发射丰富的客户(Swing、AWT、SWT)。它为支持 Java的平台提供一只点击装置。

JWS提供了许多吸引力的特点,包括但不限于:闪电屏幕、桌面整合、档案协会、automatic Update(包括 la下载和对更新内容的方案控制)、分拨本地人和安插;按平台、结构或 Java版本分列的其他资源下载、临时环境配置(最低J2SE版本、实用选择、RAM等)、利用推广对共同资源的轻松管理。
