查看本地安装的 JDK 所在位置以及 JAVA 版本

系统默认的安装处

/Library/Java/JavaVirtualMachines

配置Java

• 添加环境变量

vim  ～/.bash_profile

Add

# 安装位置
export JAVA_11_HOME="/Library/Java/JavaVirtualMachines/zulu-11.jdk/Contents/Home"
export JAVA_17_HOME="/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home"
# 默认java版本
export JAVA_HOME=$JAVA_17_HOME
# alias命令动态切换jdk版本
alias jdk11='export JAVA_HOME=$JAVA_11_HOME'
alias jdk17='export JAVA_HOME=$JAVA_17_HOME'

export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

重新加载配置文件

source /etc/profile ~/.bash_profile

备注：source后边必须跟"/etc/profile" 这个路径，否则通过alias别名切换jdk版本可能会失败
