mac zsh环境配置java_home环境变量

用zsh，修改～/.zshrc

修改这些文件之后，重修打开terminal，配置不会丢

首先确保已经安装了jdk：

## check the present running java

which java

## check java version

java -version

以zsh为例：

## check all the available jdk

/usr/libexec/java_home -V

## check the top jdk

/usr/libexec/java_home

## check some jdk (eg. version 1.7)

/usr/libexec/java_home -v 1.7

## edit .zshrc to set java_home variable

vim ~/.zshrc

## add the following line into the file

export JAVA_HOME=$(/usr/libexec/java_home)

## you can also use the following line to set the variable, which is not recommended, only for older mac os.

## export JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

##let the configuration in .zshrc take effect

source ~/.zshrc

## check if configure succeed

echo $JAVA_HOME

如果用bash，修改~/.bash_profile 或 ~/.profile；
