在Mac OS X上安装了Java 7，但终端仍在使用版本6 [英] Installed Java 7 on Mac OS X but Terminal is still using version 6

问题描述

我安装了从oracle网站下载的JDK 7u7。但安装后，终端仍显示java版本6

I've installed JDK 7u7 downloaded from oracle's website. But after installation, the terminal is still showing java version 6

$java -version
java version "1.6.0_35"
Java(TM) SE Runtime Environment (build 1.6.0_35-b10-428-11M3811)
Java HotSpot(TM) 64-Bit Server VM (build 20.10-b01-428, mixed mode)

任何想法为什么java 7没有出现？

any idea why java 7 is not showing up?

答案：
好​​的，问题已经解决了。答案如下：
我发现我的终端有一个.bash_profile，java主变量设置为1.6

export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home"

因此，这是每次打开新终端窗口时导致问题的行。
只需删除此行即可解决问题。您仍然需要遵循@aleroot所说的内容，但如果这对您不起作用，请检查.bash_profile（或.bashrc）设置文件以查看您之前是否已导出任何Java版本。

So this is the line causing the problem every time I opened a new terminal window. Simply remove this line will solve the problem. You still need to follow what @aleroot said, but if that doesn't work for you, check the .bash_profile (or .bashrc) setting file to see if you've previously exported any java version.

推荐答案

因为您需要输入Java Preferences窗格并以这种方式仅标记JVM 7：

Because you need to enter in Java Preferences pane and flag only the JVM 7 in this way :

轻松快速地打开在Mac OS X中的 Java首选项窗格中，您只需使用⌘ + SPACE 调用聚光灯并输入系统偏好设置它将显示在窗口的最后一行。

To easily and quickly open the Java Preferences pane in Mac OS X you can simply call spotlight with ⌘+SPACE and type System Preferences it will show up in the last row of the window.
