There is System.getEnv(), but it's deprecated since 1.2 - now in the new 5.0
it's been de-deprecated again. 8-)

不好整。getenv会抛出异常的。
还是启动程序时用 -D去传吧。

Oh? That's better. I hate the fact that java cannot read environmental
variables.

5.0
Well, I guess they took it out before because env variables are hardly
platform neutral, then eventually they realized everybody has to write a shell
script to convert the env variables to properties in order to start a java
program, and then shell scripts are kinda hard to be platform neutral
anyway...
