〖Linux〗多個JDK版本之間快速切換

#!/bin/sh

usage: . this_file [argvs]

jdk6_home=~/apt/jdk1.6.0_34 jdk7_home=~/apt/jdk1.7.0_67 jdk8_home=~/apt/jdk1.8.0_05

默認JDK6

case $1 in jdk6 ) export JAVA_HOME=$jdk6_home ;; jdk7 ) export JAVA_HOME=$jdk7_home ;; jdk8 ) export JAVA_HOME=$jdk8_home ;; * ) export JAVA_HOME=$jdk6_home ;; esac

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

使用方法：

　　例如：在須要切換的JDK7的時候，在Shell中執行 . [腳本文件名] jdk7

　　前提：把JDK7下載並解壓到 ~/apt/jdk1.7.0_67（根據自身需求修改）
