在java中获取环境变量的值? [英] getting environment variable's value in java?

问题描述

我已经在Windows中通过名称"sample"设置了环境变量.我可以使用以下代码获取此环境变量的值吗?

I have set an environment variable in windows by name "sample". Can I get this environment variable's value using below code?

System.getProperty("sample");

在UAT环境中，我有LINUX OS.我可以在LINUX OS中设置相同的环境变量，然后使用System.getProperty("sample")检索相同的变量吗?

in UAT environment I have LINUX OS. Can I set the same environment variable in LINUX OS and retrieve the same using System.getProperty("sample")?

我的意思是System.getProperty("sample");是否检索与操作系统无关的内容?

I mean does System.getProperty("sample"); retrieves irrespective of the operating system?

此外，我想在JSP中获取环境变量的值.我知道不建议将逻辑保留在jsp中，但仍然需要使用它.我可以在jsp中使用System.getProperty("sample");吗?请帮助我.

Also, I would like to get the environment variable's value in JSP.I know it is not recommended to keep logic in jsp but still, I need to use it. Can I use System.getProperty("sample"); in jsp? Please help me.
