国际化 Internationalization

介绍 Introduction

在创建一个新项目期间，您将被问及是否要启用国际化支持。

如果启用它，您将需要选择应用程序的母语。之后，您可以选择要安装的其他语言。如果您不想从开始支持任何其他语言，您可以随时通过运行语言子生成器添加语言。

如果您确定不会将此应用程序翻译成另一种语言，则不应启用国际化。

项目生成后如何添加语言？ How to add languages after project generation?

为此，您可以使用以下语言运行语言子生成器：

jhipster languages

请注意，如果您希望使用刚添加的语言翻译实体，则需要重新生成实体。

如何添加不支持的新语言？ How to add a new language that is not supported?

所有语言都保存在文件夹 src/main/webapp/i18n （客户端）和 src/main/resources/i18n (服务器端)

以下是安装新语言的步骤 new_lang:

1. 复制 src/main/webapp/i18/en folder to src/main/webapp/i18/new_lang (这是存储所有前端翻译的地方)
2. Translate all files under the folder src/main/webapp/i18/new_lang

3. 对于AngularJS 1，将语言代码添加 new_lang 到 LANGUAGES 定义的常量中src/main/webapp/app/components/language/language.constants.js

   .constant('LANGUAGES', [
       'en',
       'fr',
       'new_lang'
       // jhipster-needle-i18n-language-constant - JHipster will add/remove languages in this array
   ]
   

   对于Angular 2+，add the language code new_lang to the LANGUAGES constant defined in src/main/webapp/app/shared/language/language.constants.ts

   export const LANGUAGES: string[] = [
       'en',
       'fr',
       'new_lang'
       // jhipster-needle-i18n-language-constant - JHipster will add/remove languages in this array
   ];
   

4. In the src/main/resources/i18n folder, copy the messages_en.properties file to messages_new_lang.properties (这是存储服务器端翻译的地方)

5. Translate all keys in the messages_new_lang.properties file
6. For AngularJS 1 add the new language's name in the function of filter('findLanguageFromKey') in the src/main/webapp/app/components/language/language.filter.js file. For Angular 2+ add the new language's name in the languages variable of FindLanguageFromKeyPipe in the src/main/webapp/app/shared/language/language.pipe.ts

7. 对于Angular 2+，添加新的语言捆绑 webpack.common.js

    new MergeJsonWebpackPlugin({
        output: {
            groupBy: [
                { pattern: "./src/main/webapp/i18n/en/*.json", fileName: "./i18n/en.json" },
                { pattern: "./src/main/webapp/i18n/new_lang/*.json", fileName: "./i18n/new_lang.json" }
                // jhipster-needle-i18n-language-webpack - JHipster will add/remove languages in this array
            ]
        }
    })
   

新语言 new_lang 现在可以在语言菜单中使用，它可以在前端Angular应用程序和后端Spring应用程序中使用。

如何删除现有语言？ How to remove an existing language?

Here are the steps to remove a language called old_lang:

1. Remove the language folder from src/main/webapp/i18/old_lang
2. Remove the constant entry in src/main/webapp/app/components/language/language.constants.js or src/main/webapp/app/shared/language/language.constants.ts
3. Remove the src/main/resources/i18n/messages_old_lang.properties file
