我希望通过复制Java文件夹的内容并设置环境变量来确保一切都能正常工作。
我通常在虚拟机中运行安装程序，压缩\java文件夹内容，回到虚拟机的快照，然后解压缩压缩文件。
我找不到一个地方有最新的JRE / JDK压缩文件…
http://java.sun.com/javase/downloads/index.jsp
http://download.java.net/jdk6/
另外，假定sun的exe安装程序只是解压缩整个文件，而不会弄乱注册表、环境变量等等，这是否安全?

创建目标文件夹，您可以RWX(例如C:\jdk8) 从Oracle下载jdk exe(例如:jdk-8u72-windows-x64.exe) 将其中的tools.zip解压到目标文件夹中 在cmd.exe中运行: cd C: \ jdk8 在(x / r % * .pack)。\ bin \ unpack200 - r“% x”“% ~ dx % ~ px % ~ nx.jar”
这个解决方案也适用于没有Admin权限的JDK 8。

对于JDK 8u102，事情已经发生了变化，这对我来说是有效的:
下载windows JDK exe 用7-Zip打开 将内容转储到%JDK-EXE%目录中 cmd: cd %JDK-EXE%.rsrc\1033\JAVA_CAB10 命令:extrac32 111 现在在目录中有一个tools.zip，用7-Zip打开它 将内容提取到一个新目录%JDK-VERSION% cmd: cd %JDK-VERSION% cmd: / r % x (* .pack)。\ bin \ unpack200 - r“% x”“% ~ dx % ~ px % ~ nx.jar” src.zip在%JDK-EXE%中。rsrc\1033\JAVA_CAB9\110\ -拷贝到%JDK-VERSION%
现在你已经准备好了。 您可能希望将JAVA_HOME和PATH设置为指向%JDK-VERSION% dir及其BIN子目录。
不幸的是，JDK不能作为可移植的ZIP文件提供。但是，你可以遵循以下步骤:
Create working JDK directory (C:\JDK in this case) Download latest version of JDK from Oracle (for example jdk-7u7-windows-x64.exe) Download and install 7-Zip (or download 7-Zip portable version if you are not administrator) With 7-Zip extract all the files from jdk-XuXX-windows-x64.exe into the directory C:\JDK Execute the following commands in cmd.exe: cd C:\JDK\.rsrc\1033\JAVA_CAB10 extrac32 111 Unpack C:\JDK\.rsrc\1033\JAVA_CAB10\tools.zip with 7-zip Execute the following commands in cmd.exe: cd C:\JDK\.rsrc\1033\JAVA_CAB10\tools\ for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar" (this will convert all .pack files into .jar files) Copy all contents of C:\JDK\.rsrc\1033\JAVA_CAB10\tools where you want your JDK to be Setup JAVA_HOME and PATH manually to point to your JDK dir and its BIN subdirectory.
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
下面提示中的命令包装为批处理脚本。保存为unpack.bat。然后将它与jdk/jre提取文件一起放置到dir。
@echo off
cd /d "%~dp0"
for /r %%x in (*.pack) do .\bin\unpack200 -r "%%x" "%%~dx%%~px%%~nx.jar"
Sun JVM可以作为MSI，它可以从脚本执行。
