You can just use 7zip (or another similar app) to get the dirs inside the core.zip file that's bundled in the installer. Just use 7zip to browse the exe, you'll see a core.zip file which has all the files that usually go inside "jreX" dir (where X is the major version number). As for setting env variables and the such, you can follow the other answers. If all you want is a portable jre (for example, you can run your jars by using java.exe jarfile or javaw.exe jarfile) then this solution will do. This is very similar to copying the jre dir from one place to another

Sun JVM可以作为MSI，它可以从脚本执行。

我发现你可以在Wine中运行安装程序。如此:

WINEPREFIX=/home/jason/ jre-7u11-windows-i586.exe

一旦完成，你可以压缩/home/jason/ Java/ drive_c/ program \ Files\ \(x86\)/Java/jre7/

这应该也适用于jdk

OSX指令

用jdk-8u74-macosx-x64.dmg测试。

从Oracle下载。dmg 挂载磁盘映像 提取.pkg，拖动它。不要双击(它会安装)。 打开一个终端并cd到包中。 Mkdir jdk-$version && CD jdk-$version xar -xf ../JDK*.pkg cd jdkTAB tar zxf有效负载 “Contents/Home”文件夹中包含JDK

我就是这么做的，

从安装exe开始，等待下面的屏幕，

访问C:\Program Files (x86)\Java并将JDK复制到另一个地方。

单击“x”取消安装并卸载JDK。

将复制的JDK复制回C:\Program Files (x86)\Java或您选择的其他文件夹
