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?

您可以从上面的链接获取jre-7u75-windows-i586.zip。

谢谢关心;JDK似乎不与Windows注册表交互。
但是，JRE在某些情况下是这样的。

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
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.
得到广泛好评的答案很好，我已经用了很长一段时间，以这个bat文件的形式:
@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET ROOT=%cd%
REM Get the tools.zip from the innards of the installer
7z e *.exe .rsrc/1033/JAVA_CAB10/111
7z e 111 7z x tools.zip
REM Extract all
7z x -aoa tools.zip -ojdk
del tools.zip
del 111
REM Searching directory structure from root for subfolders and zipfiles.
FOR /F "delims==" %%d IN ('dir /ogne /ad /b /s "%ROOT%"') DO (
echo Descending into %%d
FOR /F "delims==" %%f IN ('dir /b "%%d\*.pack"') DO (
echo Extracting "%%d\%%f"
REM Extract all packs into jars.
jdk\bin\unpack200 -r "%%d\%%f" "%%d\%%~nf.jar"
)
)
ENDLOCAL
pause;
它需要访问7zip的路径，并且必须在你选择的JDK的文件夹中运行(它会找到它，因为上面有*.exe)。
在8u144上也能用，我猜在8u20上也能用。
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
