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?

下载javase和JDK
jdk从Oracle网站http://www.oracle.com/technetwork/java/javase/downloads/index.html下载 解压缩exe。例如:jdk-8u5-windows-x64.exe 将以下文件:tools.zip(在解压缩文件夹下找到)解压缩到所需的JAVA_HOME。 更新JAVA_HOME环境变量以指向所需的路径。
测试版本:jdk-7u60-windows-x64.exe, jdk-7u60-windows-x64.exe
下载javaee和JDK
jdk从Oracle网站http://www.oracle.com/technetwork/java/javaee/downloads/index.html下载 解压缩exe。例如:jdk-7u55-windows-x64.exe Product\Packages\jdk.zip(在解压缩文件夹下找到)解压缩到所需的JAVA_HOME。 更新JAVA_HOME环境变量以指向所需的路径。
已测试版本:jdk-7u55-windows-x64.exe

The Process described by Igor and CharlesB Works to me, since IDE's like NetBeans and Eclipse permit specify the location of the JDK, even software like Apache Tomcat (the ZIP Distribution) use BASH - FILES to set it up (then specify the JDK location using relatives URI). I Have a USB-HardDisk With NetBeans, Eclipse, Apache Tomcat working with a JDK in "portable mode". I Had a way to extract a copy of the JDK from the installers files: Install it, Copy it in other place and then uninstall it. A dirty way to extract it, but was successfull. The place to put EXTRA - LIBS was: %PLACE_WHERE_JDK_ARE%\jre\lib\ext
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。

至少可以帮助你避免讨厌的预加载安装程序直接进入SDK。
从那里，我将把它安装在一个一次性的VM，在你的旧的杂乱的PC或其他地方，然后转移结果
C:\Program Files (x86)\Java\jre7
(或类似)到你的新机器，设置很少的常用ENV变量，理想情况下，你就可以实现了，没有所有的营销垃圾和潜在的捆绑。当然，也没有安全的频繁自动更新。
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.
