배치 파일을 사용하여 Java 설치 경로를 가져 오시겠습니까?

Question

• 배치 스크립트를 사용하여 JAVA_HOME 변수를 설정해야합니다.
• 코드는 시도했지만 사용하지는 마십시오.

는 ("java.exe를")에서/f를 %% j에 대한 @echo을 %% ~ DP의 $ 경로 :. j는

위의 스크립트가 비어

제공

FOR/F %% 설정 않는 IN ('REG QUERY "HKLM \ SOFTWARE \ Java 소프트웨어 \ 자바 런타임 환경"/ V CurrentVersion을') 대답 : CurVer = %% B

"= 2 개 토큰 = 2 * 이동"을

위의 스크립트가 제공

1.6 디렉토리에 java.exe/B/S

위의 스크립트가 제공 C : \ WINDOWS \ system32를 실제로 C에 설치된 자바 : \ 프로그램 파일 \ 자바 \ jdk1.6.0_31

• JAVA_HOME을 C : \ Program Files \ Java \ jdk1.6.0_31로 설정해야합니다.

어떻게 만드나요? 에 대해

Answer 1

방법 :

setx JAVA_HOME "path/to/it" 

이 %JAVA_HOME%

Answer 2

을 수행하여 그것을 얻을 당신의 JAVA_HOME이 someName.bat로 실행이 configured.save 경우이 작동합니다.

Answer 3

내가 가진를 해결책. 이것은 정확히 설치된 경로를 제공합니다. 자바 1.6 JavaHome에

FOR /F "skip=2 tokens=2*" %%A IN ('REG QUERY "HKLM\Software\JavaSoft\Java Development Kit" /v CurrentVersion') DO 
set CurVer=%%B ECHO %CurVer% 


FOR /F "skip=2 tokens=2*" %%A IN ('REG QUERY "HKLM\Software\JavaSoft\Java Development Kit\%CurVer%" /v JavaHome') 
DO set JavaPath=%%B ECHO %JavaPath% 

Answer 4

경로 :

@ECHO OFF &SETLOCAL 
FOR /F "tokens=2*" %%a IN ('REG QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.6" /v JavaHome') DO set "JavaHome16=%%b" 
ECHO %JavaHome16% 

경로 자바 1.7 JavaHome에 :

@ECHO OFF &SETLOCAL 
FOR /F "tokens=2*" %%a IN ('REG QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7" /v JavaHome') DO set "JavaHome17=%%b" 
ECHO %JavaHome17%
