Mac OSX 10.9以后系统就自带了Java 6的环境,路径在:

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

如果想要升级到Java 7的环境,步骤如下:

  • 1.到Oracle官网下载系统对应JDK7的安装包, 地址在这里,安装成功后JDK7默认的路径在:
/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
  • 2.安装成功后配置环境变量

在.bash_profile文件中添加:

export JAVA_HOME=$(/usr/libexec/_)
export PATH=$JAVA_HOME/bin:$PATH

需要说明的是Mac OSX 10.5之后苹果就建议设置$JAVA_HOME变量到/usr/libexec/_

  • 3.设置完成后输入下列命令测试下
$java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
