官方下载地址

这个是官方新发布的适配了M1、M2芯片的ARM64版本的jdk8，再也不用去第三方下载了，也不用满世界的去找第三方jdk缺少的jar包了，而且更快更强！！

可以下载免安装版， 这样就可以配置多个版本的jdk了，配置如下

m@mdeMacBook-Pro ~ % vim .zprofile# JDK 配置export JAVA_8_HOME=/Users/m/dev_tools/jdk/jdk1.8.0_381.jdk/Contents/Homeexport JAVA_11_HOME=/Users/m/dev_tools/jdk/jdk-11.0.20.jdk/Contents/Homeexport JAVA_17_HOME=/Users/m/dev_tools/jdk/jdk-17.0.8.jdk/Contents/Home# 默认JDK版本export JAVA_HOME=$JAVA_8_HOME# 多版本切换（取了别名，更方便切换）alias jdk8="export JAVA_HOME=$JAVA_8_HOME"alias jdk11="export JAVA_HOME=$JAVA_11_HOME"alias jdk17="export JAVA_HOME=$JAVA_17_HOME"export PATH=$JAVA_HOME/bin:$PATH

使配置文件生效

m@mdeMacBook-Pro ~ % source /etc/profile~/.zprofile

切换jdk版本
