Is there an open source java enum of ISO 3166-1 country codes
提问by Jason Jenkins
Does anyone know of a freely available java 1.5 package that provides a list of ISO 3166-1 country codes as a enum or EnumMap? Specifically I need the "ISO 3166-1-alpha-2 code elements", i.e. the 2 character country code like "us", "uk", "de", etc. Creating one is simple enough (although tedious), but if there's a standard one already out there in apache land or the like it would save a little time.
有谁知道一个免费提供的 java 1.5 包，它提供了一个 ISO 3166-1 国家代码列表作为枚举或 EnumMap？具体来说，我需要“ISO 3166-1-alpha-2 代码元素”，即 2 个字符的国家/地区代码，如“us”、“uk”、“de”等。创建一个很简单（虽然很乏味），但是如果在 apache 土地或类似的地方已经有一个标准的，它会节省一点时间。

This code gets 242 countries in Sun Java 6:
此代码在 Sun Java 6 中获取 242 个国家/地区：
String[] countryCodes = Locale.getISOCountries();
Though the ISO websiteclaims there are 249 ISO 3166-1-alpha-2 code elements, though the javadoclinks to the same information.

There is an easy way to generate this enum with the language name. Execute this code to generate the list of enum fields to paste :
有一种简单的方法可以使用语言名称生成此枚举。执行此代码以生成要粘贴的枚举字段列表：
/**
* This is the code used to generate the enum content
*/
public static void main(String[] args) {
String[] codes = java.util.Locale.getISOLanguages();
for (String isoCode: codes) {
Locale locale = new Locale(isoCode);
System.out.println(isoCode.toUpperCase() + "(\"" + locale.getDisplayLanguage(locale) + "\"),");
}
}

Here's how I generated an enum with country code + country name:
下面是我如何生成一个带有国家代码 + 国家名称的枚举：
package countryenum;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Locale;
public class CountryEnumGenerator {
public static void main(String[] args) {
String[] countryCodes = Locale.getISOCountries();
List<Country> list = new ArrayList<Country>(countryCodes.length);
for (String cc : countryCodes) {
list.add(new Country(cc.toUpperCase(), new Locale("", cc).getDisplayCountry()));
}
Collections.sort(list);
for (Country c : list) {
System.out.println("/**" + c.getName() + "*/");
System.out.println(c.getCode() + "(\"" + c.getName() + "\"),");
}
}
}
class Country implements Comparable<Country> {
private String code;
private String name;
public Country(String code, String name) {
super();
this.code = code;
this.name = name;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public int compareTo(Country o) {
return this.name.compareTo(o.name);
}
}

This still does not answer the question. I was also looking for a kind of enumerator for this, and did not find anything. Some examples using hashtable here, but represent the same as the built-in get
这仍然没有回答问题。我也在为此寻找一种枚举器，但没有找到任何东西。此处使用哈希表的一些示例，但表示与内置 get 相同
I would go for a different approach. So I created a script in python to automatically generate the list in Java:
我会采用不同的方法。所以我在python中创建了一个脚本来自动生成Java中的列表：
#!/usr/bin/python
f = open("data.txt", 'r')
data = []
cc = {}
for l in f:
t = l.split('\t')
cc = { 'code': str(t[0]).strip(),
'name': str(t[1]).strip()
}
data.append(cc)
f.close()
for c in data:
print """
/**
* Defines the <a href="http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2">ISO_3166-1_alpha-2</a>
* for <b><i>%(name)s</i></b>.
* <p>
* This constant holds the value of <b>{@value}</b>.
*
* @since 1.0
*
*/
public static final String %(code)s = \"%(code)s\";""" % c
where the data.txt file is a simple copy&paste from Wikipedia table (just remove all extra lines, making sure you have a country code and country name per line).
其中 data.txt 文件是从 Wikipedia 表中简单的复制和粘贴（只需删除所有多余的行，确保每行都有一个国家/地区代码和国家/地区名称）。
Then just place this into your static class:
然后把它放到你的静态类中：
/**
* Holds <a href="http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2">ISO_3166-1_alpha-2</a>
* constant values for all countries.
*
* @since 1.0
*
* </p>
*/
public class CountryCode {
/**
* Constructor defined as <code>private</code> purposefully to ensure this
* class is only used to access its static properties and/or methods.
*/
private CountryCode() { }
/**
* Defines the <a href="http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2">ISO_3166-1_alpha-2</a>
* for <b><i>Andorra</i></b>.
* <p>
* This constant holds the value of <b>{@value}</b>.
*
* @since 1.0
*
*/
public static final String AD = "AD";
//
// and the list goes on! ...

}

Now an implementation of country code (ISO 3166-1alpha-2/alpha-3/numeric) list as Java enum is available at GitHub under Apache License version 2.0.
现在，国家代码 ( ISO 3166-1 alpha-2/ alpha-3/ numeric) 列表作为 Java 枚举的实现可在 Apache 许可证版本 2.0 下在 GitHub 上获得。
Example:
例子：
CountryCode cc = CountryCode.getByCode("JP");
System.out.println("Country name = " + cc.getName()); // "Japan"
System.out.println("ISO 3166-1 alpha-2 code = " + cc.getAlpha2()); // "JP"
System.out.println("ISO 3166-1 alpha-3 code = " + cc.getAlpha3()); // "JPN"
System.out.println("ISO 3166-1 numeric code = " + cc.getNumeric()); // 392

CountryCode enum was packaged into com.neovisionaries.i18n with other Java enums, LanguageCode (ISO 639-1), LanguageAlpha3Code (ISO 639-2), LocaleCode, ScriptCode (ISO 15924) and CurrencyCode (ISO 4217) and registered into the Maven Central Repository.
CountryCode 枚举与其他 Java 枚举、LanguageCode ( ISO 639-1)、LanguageAlpha3Code ( ISO 639-2)、LocaleCode、ScriptCode ( ISO 15924) 和 CurrencyCode ( ISO 4217)一起打包到 com.neovisionaries.i18n并注册到 Maven Central存储库。

I didn't know about this question till I had just recently open-sourced my Java enum for exactly this purpose! Amazing coincidence!
我不知道这个问题，直到我最近刚刚为此目的开源了我的 Java 枚举！惊人的巧合！
I put the whole source code on my blog with BSD caluse 3 license so I don't think anyone would have any beefs about it.
我使用 BSD caluse 3 许可证将整个源代码放在我的博客上，所以我认为没有人会对此有任何异议。

Hope it is useful and eases development pains.

If you are already going to rely on Java locale, then I suggest using a simple HashMap instead of creating new classes for countries etc.
如果您已经打算依赖 Java 语言环境，那么我建议使用简单的 HashMap 而不是为国家/地区等创建新类。
Here's how I would use it if I were to rely on the Java Localization only:
如果我仅依赖 Java 本地化，我将如何使用它：
private HashMap<String, String> countries = new HashMap<String, String>();
String[] countryCodes = Locale.getISOCountries();
for (String cc : countryCodes) {
// country name , country code map
countries.put(new Locale("", cc).getDisplayCountry(), cc.toUpperCase());
}
After you fill the map, you can get the ISO code from the country name whenever you need it. Or you can make it a ISO code to Country name map as well, just modify the 'put' method accordingly.
填写地图后，您可以在需要时从国家/地区名称中获取 ISO 代码。或者您也可以将其设为国家名称映射的 ISO 代码，只需相应地修改 'put' 方法。

Not a java enum, but a JSON version of this is available at http://country.io/names.json
不是 java 枚举，而是http://country.io/names.json提供的 JSON 版本

If anyone is already using the Amazon AWS SDK it includes com.amazonaws.services.route53domains.model.CountryCode. I know this is not ideal but it's an alternative if you already use the AWS SDK. For most cases I would use Takahiko's nv-i18nsince, as he mentions, it implements ISO 3166-1.
如果有人已经在使用 Amazon AWS 开发工具包，它会包含com.amazonaws.services.route53domains.model.CountryCode. 我知道这并不理想，但如果您已经使用 AWS 开发工具包，它是一种替代方法。在大多数情况下，我会使用 Takahiko 的，nv-i18n因为正如他所提到的，它实现了 ISO 3166-1。

I have created an enum, which you address by the english country name. See country-util.
On each enum you can call getLocale()to get the Java Locale.
我创建了一个枚举，您可以使用英文国家/地区名称进行寻址。请参阅country-util。
在每个枚举上，您可以调用getLocale()以获取 Java 语言环境。
From the Locale you can get all the information you are used to, fx the ISO-3166-1 two letter country code.
从区域设置中，您可以获得您习惯的所有信息，例如 ISO-3166-1 两个字母的国家/地区代码。
public enum Country{
ANDORRA(new Locale("AD")),
AFGHANISTAN(new Locale("AF")),
ANTIGUA_AND_BARBUDA(new Locale("AG")),
ANGUILLA(new Locale("AI")),
//etc
ZAMBIA(new Locale("ZM")),
ZIMBABWE(new Locale("ZW"));
private Locale locale;
private Country(Locale locale){
this.locale = locale;
}
public Locale getLocale(){
return locale;
}
Pro:
亲：
- Light weight
- Maps to Java Locales
- Addressable by full country name
- Enum values are not hardcoded, but generated by a call to Locale.getISOCountries(). That is: Simply recompile the project against the newest java version to get any changes made to the list of countries reflected in the enum.
- 轻的
- 映射到 Java 语言环境
- 可按国家全名寻址
- 枚举值不是硬编码的，而是通过调用 Locale.getISOCountries() 生成的。即：只需根据最新的 Java 版本重新编译项目，即可获取对枚举中反映的国家/地区列表所做的任何更改。
Con:
骗局：
- Not in Maven repository
- Most likely simpler / less expressive than the other solutions, which I don't know.
- Created for my own needs / not as such maintained. - You should probably clone the repo.
- 不在 Maven 存储库中
- 与我不知道的其他解决方案相比，很可能更简单/缺乏表现力。
- 为我自己的需要而创建/不是这样维护的。- 你应该克隆 repo。
