怎么用reg文件添加环境变量，下面的方法不行。请高手解答。

Posted 2023-05-10

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
"Path"=%path%;"C:\\Program Files"

此处虽然可以引用已经存在的环境变量，但是因为这里是在修改Path变量，所以引用自身会发生问题(但是引用其他的环境变量是可以的)

可以使用批处理解决这个问题。

将下面的代码保存为1.bat

@echo off
echo Windows Registry Editor Version 5.00>path.reg
echo [HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment]>>path.reg
echo\\>>path.reg
echo "Path"="%path%;D:\\test\\" >>path.txt
(for /f "tokens=1* delims=:" %%i in ('findstr /n .* path.txt') do (
set "line=%%j"
setlocal enabledelayedexpansion
if "!line!"=="" (echo.!line!) else (
set "line=!line:\\=\\\\!"
echo.!line!
endlocal
)))>tmp.txt
move tmp.txt path.txt
type path.txt>>path.reg
del path.txt
pause

D:\\test\\是你追加的新的内容，相应修改即可

然后会得到一个path.reg双击导入注册表即可。
注意：要使修改生效，需要重启电脑。

docker中，jdk用镜像 怎么配置环境变量

docker中，jdk用镜像配置环境变量的方法如下：
一、安装 JDK
1、首先，解压 JDK 程序包：
tar -zxf /mnt/software/jdk-7u67-linux-x64.tar.gz -C .

2、重命名 JDK 目录：
mv jdk1.7.0_67/ jdk/

二、设置环境变量
首先，编辑.bashrc文件
vi ~/.bashrc

然后，在该文件末尾添加如下配置：
export JAVA_HOME=/opt/jdk
export PATH=$PATH:$JAVA_HOME

最后，需要使用source命令，让环境变量生效：
source ~/.bashrc 参考技术A 使用Docker 进行Java 开发步骤：
1、准备工作
现在最流行的是选择Spark，它是一个基于Java 8的极小的框架。Spark使用Maven作为构建工具。
2、源代码和配置文件
在这个例子中你要增加三个文件：
Maven的配置文件： pom.xml
一个Java类：Hello.java
一个Dockerfile
例子：

hello.java:
package sparkexample;
import static spark.Spark.get;
public class Hello
public static void main(String[] args)
get("/", (req, res) ->
return "hello from sparkjava.com";
);
