Mac下安裝和管理Java

2020-06-16 18:07:26

Mac OSX 10.9以後系統就自帶了Java 6的環境,路徑在:

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

如果想要安裝升級到Java 7的環境,步驟如下:

  • 1.到Oracle官網下載系統對應JDK7的安裝包, 地址在這裡,安裝成功後JDK7預設的路徑在:
/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
  • 2.安裝成功後設定環境變數

在.bash_profile檔案中新增:

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

需要說明的是Mac OSX 10.5之後蘋果就建議設定$JAVA_HOME變數到/usr/libexec/java_home

  • 3.設定完成後輸入下列命令測試下
$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)

# 檢視系統安裝的java版本
$/usr/libexec/java_home -V
Matching Java Virtual Machines (3):
1.7.0_60, x86_64:	"Java SE 7"	/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
1.6.0_65-b14-462, x86_64:	"Java SE 6"	/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
1.6.0_65-b14-462, i386:	"Java SE 6"	/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

# 返回系統安裝的java最高版本
$/usr/libexec/java_home
/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
