问题描述
我的所有 ResourceBundle 值都在一个表格中，并根据要求进行了格式化.我必须根据页面顶部下拉菜单中的用户选择更改网站上的语言.
I have all my ResourceBundle values in a table and formatted as per requirement. I have to change the languages on the website based on user selection in a dropdown at the top of the page.
如果我使用诸如 en_US 之类的语言代码，那么它可以正常工作.如果我使用 en-US 作为语言代码，则它不起作用.可能是什么问题?这样做的正确方法是什么?
If I use a language code such as en_US, then it works fine. If I use en-US as a language code, then it doesn't work. What might be the problem? Which is the correct way to do this?
推荐答案
en"是ISO 639指定的语言代码.而US是3166指定的国家代码.
在 Java 中，Locale 对象将语言识别为 languageCode_countryCode(例如 en_US)而不是 languageCode-countryCode.
"en" is the language code specified by ISO 639. while US is country code specified by 3166.
In Java, the Locale object recognizes the language as languageCode_countryCode (e.g. en_US) and not as languageCode-countryCode.
