Mac修改文件 ~/.bash_profile

代码语言：javascript复制
# 定义不同版本jdk的java_home
export JAVA_8_HOME=/Users/maruifu/work/tools/java/jdk1.8.0_411.jdk/Contents/Home
export JAVA_17_HOME=/Users/maruifu/work/tools/java/jdk-17.0.11.jdk/Contents/Home
export JAVA_21_HOME=/Users/maruifu/work/tools/java/jdk-21.0.4.jdk/Contents/Home

# 给JAVA_HOME默认值  这个必须要有
export JAVA_HOME=$JAVA_17_HOME


# alias命令动态切换JDK版本
alias jdk8="export JAVA_HOME=$JAVA_8_HOME"
alias jdk17="export JAVA_HOME=$JAVA_17_HOME"
alias jdk21="export JAVA_HOME=$JAVA_21_HOME" 



PATH=$PATH:$JAVA_HOME/bin
export PATH

修改完后，执行source ~/.bash_profile 命令使改动生效
