Java proxy settings - Ubuntu
提问by nepdev
How do I set the Java proxy settings in Ubuntu (10.04 or 12.04), from the command line? What I am aiming at is to get direct connection, but by default it takes it from browser settings which are meant to go via a proxy - just I don't want Java to go via the proxy.
如何从命令行在 Ubuntu（10.04 或 12.04）中设置 Java 代理设置？我的目标是获得直接连接，但默认情况下，它从浏览器设置中获取，这些设置旨在通过代理 - 只是我不希望 Java 通过代理。
I am running an application server in Ubuntu which serves remote desktop sessions. I can put the Java control panel into the user's desktop, and then they (each individual user) can set the proxy settings under Network Settings. However - this means I have to tell each user to make this setting, which is not workable.
我在 Ubuntu 中运行一个应用程序服务器，它提供远程桌面会话。我可以将 Java 控制面板放入用户的桌面，然后他们（每个单独的用户）可以在网络设置下设置代理设置。但是 - 这意味着我必须告诉每个用户进行此设置，这是行不通的。
I want it set via some command line or environment variable on the server itself, so it defaults to "direct connection". I am not familiar with Java programming and it won't help much to give me Java code for this, I think it must be possible to set the defaults upon Java startup? Any pointers are welcome.
我希望它通过服务器本身的一些命令行或环境变量设置，所以它默认为“直接连接”。我不熟悉 Java 编程，为此提供 Java 代码也无济于事，我认为必须可以在 Java 启动时设置默认值？欢迎任何指点。

Instead of command line you can edit $javaDirectory/jre/lib/net.properties.
您可以编辑$javaDirectory/jre/lib/net.properties.
Remove #in-front of:
删除#前面的：
http.proxyHost="proxy host"
http.proxyPort="proxy port"
and set your proxy there.
并在那里设置您的代理。

You can export the http_proxyenvironment variable via command line.
您可以通过命令行导出http_proxy环境变量。
Ex:
前任：
$ export http_proxy=http://proxy-server:port
There is a environment variable ftp_proxyalso, just in case you need it.
还有一个环境变量ftp_proxy，以防万一您需要它。
