如何从Java中的String表示中获取Locale？ [英] How to get Locale from its String representation in Java?

问题描述

是否有一种巧妙的方法来获取区域设置来自其程序化名称的实例，由Locale的 toString（）方法返回？一个明显而丑陋的解决方案是解析String然后根据它构建一个新的Locale实例，但也许有更好的方法/就绪解决方案呢？

Is there a neat way of getting a Locale instance from its "programmatic name" as returned by Locale's toString() method? An obvious and ugly solution would be parsing the String and then constructing a new Locale instance according to that, but maybe there's a better way / ready solution for that?

需求是我想在SQL数据库中存储一些特定于语言环境的设置，包括Locales本身，但将序列化的Locale对象放在那里会很难看。我宁愿存储他们的字符串表示，这些表示似乎相当充分。

The need is that I want to store some locale specific settings in a SQL database, including Locales themselves, but it would be ugly to put serialized Locale objects there. I would rather store their String representations, which seem to be quite adequate in detail.

推荐答案

参见 Locale.getLanguage（）， Locale.getCountry（） ...将此组合存储在数据库中而不是中编程名称 ...

如果要重新构建Locale，请使用 public Locale（String language，String country）

See the Locale.getLanguage(), Locale.getCountry()... Store this combination in the database instead of the "programatic name"...
When you want to build the Locale back, use public Locale(String language, String country)

以下是示例代码:)

// May contain simple syntax error, I don't have java right now to test..
// but this is a bigger picture for your algo...
public String localeToString(Locale l) {
    return l.getLanguage() + "," + l.getCountry();
}

public Locale stringToLocale(String s) {
    StringTokenizer tempStringTokenizer = new StringTokenizer(s,",");
    if(tempStringTokenizer.hasMoreTokens())
    String l = tempStringTokenizer.nextElement();
    if(tempStringTokenizer.hasMoreTokens())
    String c = tempStringTokenizer.nextElement();
    return new Locale(l,c);
}
