JAR安装程序，可自动检测Java是否存在并自动启动应用程序 [英] JAR installer that auto-detects if Java is there and autostarts the application
问题描述
我需要构建一个执行以下操作的安装程序：
I need to build an installer that does the following:
- 在客户端上安装我的jar。
- 自动检测是否安装了JRE（在这种情况下不会重新安装），否则安装它时无需用户点击其他按钮。
- 自动启动客户端启动时的应用程序。
- 适用于Windows，Mac和Linux。
- Installs my jar on the client.
- Auto-detects if JRE is installed (in which case it does not re-install it), otherwise installs it without the user clicking on another button.
- Auto-starts the application when the client is booted.
- Works across Windows, Mac and Linux.
任何想法如何去做？
推荐答案
如果商业工具还可以，我可以推荐 install4j 。 1,2和4很容易用它做，但大约3我不确定。 编辑：您可以通过将您的应用程序安装为服务来实现这一点，install4j支持所有平台。引用其功能页面：
If a commercial tool is ok, I can recommend install4j. 1, 2 and 4 are easy to do with it, but about 3 I'm not sure. Edit: You could probably achieve that by installing your app as a "service", which install4j supports for all platforms. Quoting from its Features page:
install4j完全支持
生成和安装服务
（守护进程）。对于服务，install4j
在
Windows上生成服务可执行文件，在Mac OS X上生成启动项，在Unix / Linux
平台上生成
启动/停止脚本。
install4j offers full support for generating and installing services (daemons). For services, install4j generates service executables on Windows, startup items on Mac OS X and start/stop scripts on Unix/Linux platforms.
编辑：关于＃2，JRE检测：install4具有非常好的，灵活的JRE捆绑/检测选项。您可以包含JRE（静态或动态，共享或不共享）或者更喜欢使用已存在的JRE，并可以从安装程序中下载JRE作为后备。请查看以下文档：安装程序如何查找JRE 和 JRE Bundles 。
Edit: Regarding #2, JRE detection: install4 has pretty nice, flexible options for JRE bundling/detecting. You can include a JRE (statically or dynamically, shared or not) or prefer to use one already present, with the possibility to download a JRE from within your installer as a fallback. Check these docs for more: How Installers Find a JRE and JRE Bundles.
