确保正确设置JAVA_HOME [英] Making sure JAVA_HOME is correctly set

问题描述

对Java和Mac都很新......我想确保JAVA_HOME设置在其他程序中，我可以使用它的路径。
所以我做了一些谷歌搜索，这是我得到的：

Pretty new to Java and also to Mac ... I want to make sure JAVA_HOME is set so in other programs I can use its path. So I did some Googling and here is what I got:

如果我在终端I输入 / usr / libexec / java_home 得到这个：
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
但如果我输入 echo $ JAVA_HOME 在终端，我什么都没收到。

If I enter /usr/libexec/java_home in terminal I get this: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home but if I enter echo $JAVA_HOME in terminal, I don't get anything back.

你能告诉我这里发生了什么吗？

Can you please tell me what is going on in here?

谢谢。

推荐答案

OSX上默认情况下未设置JAVA_HOME。您可以通过打开终端并执行以下命令来解决此问题：

JAVA_HOME isn't set by default on OSX. You can resolve this by opening terminal and executing the following:

echo "export JAVA_HOME=`/usr/libexec/java_home`" >> ~/.profile    
. ~/.profile

这将导致JAVA_HOME在启动时设置（而不仅仅是当前会话） ，并立即添加它。

This will cause JAVA_HOME to be set on startup (rather than just the current session), and immediately add it.
