设置环境变量在Windows 8上不起作用

Question

我使用此命令设置环境变量，但我不知道它为什么不起作用

D:\Developing tools\apache-tomcat-platform\bin>setx JAVA_HOME "C:\Program Files\
Java\jdk1.7.0_51"

SUCCESS: Specified value was saved.

D:\Developing tools\apache-tomcat-platform\bin>startup.bat
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program

Answer 1

只需重新启动电脑即可解决问题：）
