java 环境变量自动设置 注册表方法

哪位批处理高手给修改一下

不用写入文本中，直接传值

感觉就方便些@echo off
for %%i in (c d e f g h) do (
dir /s/b %%i:/jdk1.* >> e:/file.txt
)
for /f "delims=" %%s in (e:/file.txt) do (
@echo %%s
IF EXIST %%s/bin/java.exe (
@echo jdk安装目录为:%%s
@echo JAVA_HOME =%%s

@reg add "HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Control/Session Manager/Environment" /v JAVA_HOME /t REG_SZ /d "%%s" /f

@reg add "HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Control/Session Manager/Environment" /v CLASSPATH /t REG_SZ /d "%%s/lib/*.jar" /f

@reg add "HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Control/Session Manager/Environment" /v PATH /t REG_SZ /d "%%s/bin" /f

@echo on
@echo Java 2 SDK 环境参数设置完毕，正常退出。
@echo off
pause
)
)
@del del e:/file.txt

如果不能自动设置

就将%JAVA_HOME% 换成%%s
