Setting java locale settings
提问by
When I use the default java locale on my linux machine it comes out with the US locale settings, where do I change this so that it comes out with the correct locale?
当我在我的 linux 机器上使用默认的 java 语言环境时，它带有美国语言环境设置，我应该在哪里更改它以使其具有正确的语言环境？

I believe java gleans this from the environment variables in which it was launched, so you'll need to make sure your LANG and LC_* environment variables are set appropriately.
我相信 java 从启动它的环境变量中收集到这一点，因此您需要确保正确设置了 LANG 和 LC_* 环境变量。
The locale manpagehas full info on said environment variables.
语言环境联机帮助页包含有关所述环境变量的完整信息。

You could call during init or whatever Locale.setDefault()or -Duser.language=, -Duser.country=, and -Duser.variant= at the command line. Here's something on Sun's site.
您可以在 init 或任何Locale.setDefault()或 -Duser.language=、-Duser.country= 和 -Duser.variant= 期间在命令行调用。这是 Sun 网站上的一些内容。

One way to control the locale settings is to set the java system properties user.language and user.region.
控制区域设置的一种方法是设置 java 系统属性 user.language 和 user.region。

With the user.language, user.countryand user.variantproperties.
与user.language,user.country和user.variant属性。
Example:
例子：
java -Duser.language=th -Duser.country=TH -Duser.variant=TH SomeClass
java -Duser.language=th -Duser.country=TH -Duser.variant=TH SomeClass

If you are on Mac, simply using System Preferences -> Languages and dragging the language to test to top (before English) will make sure the next time you open the App, the right locale is tried!!
如果您使用的是 Mac，只需使用 System Preferences -> Languages 并将要测试的语言拖到顶部（在英语之前）将确保您下次打开应用程序时尝试正确的语言环境！！

I had to control this in a script that ran on a machine with French locale, but a specific Java program had to run with en_US. As already pointed out, the following works:
我必须在使用法语语言环境的机器上运行的脚本中控制它，但特定的 Java 程序必须使用 en_US 运行。正如已经指出的，以下工作：
java -Duser.language=en -Duser.country=US ...
Alternatively,
或者，
LC_ALL=en_US.UTF-8 java ...
I prefer the latter.
我更喜欢后者。

For tools like jarsignerwhich is implemented in Java.
对于像jarsigner在 Java 中实现的工具。

On linux, create file in /etc/default/localewith the following contents
在linux上，/etc/default/locale使用以下内容创建文件
LANG=en.utf8
and then use the sourcecommand to export this variable by running
然后使用source命令通过运行导出此变量
source /etc/default/locale
The source command sets the variable permanently.
source 命令永久设置变量。

If you ever want to check what locale or character set java is using this is built into the JVM:
如果您想检查 java 正在使用的语言环境或字符集，这内置于 JVM 中：
java -XshowSettings -version
and it will dump out loads of the settings it's using. This way you can check your LANGand LC_*values are getting picked up correctly.
它会转储它正在使用的设置的负载。通过这种方式，您可以检查您的LANG和LC_*值是否被正确提取。
