1. When login is supported, specify the language, or switch the language after login (param_lang=en)

2. Support Cookie Storage Language Settings, Use Session Storage without Cookie, Support Mobile

3. Support property files and databases to store translations and facilitate the management of translated data.

4. Translatable: Fixed data (e.g. page title, label, message prompt), dynamic data (e.g. menu data, dictionary data, etc.)

5. Chinese free zh_CN translation, such as: text('Hello'), can not find the corresponding key directly output the original "Hello"

6. Support kay and translation parameters, such as text('Today's Day {0}, 3), output "Today's Day 3"

Language file

Backend language file

Fixed Data Language

Text translations that do not change, such as a prompt, field label, list title, button text, etc., need to be put in properties.

File directory structure, supporting modular categorization language file structure, as follows:

/ src/main/resources/messages/module encoding/i18n_language encoding.

For example: msg module en translation configuration:

/src/main/resources/messages/msg/i18n_en.properties

Document content:

• File content is stored in key=value mode, such as: Hello = Hello
• If the Key contains spaces, you can use the "escape, such as Ti intersection = Submit
• Parametric translations, such as today's {0} day. = Today is the {0} day.

Maintain the newly added language in the system dictionary: sys_lang_type, which is coded as language coding;

Dynamic Data Language

Business or administrator can modify or configure some text translation through database, such as menu name, dictionary name, dictionary value, etc.

These can be logged in through the system account, enter the menu "System Management - > System Settings - > Internationalization Management" to add translations.

Front-end language file

Expand language files according to requirements, such as:

<script src="${ctxStatic}/modules/i18n/i18n_${lang()}.js" ></script>

Examples are as follows:

window.jeesiteMessage = $.extend({}, window.jeesiteMessage, {
    'Hello' : 'Hello',
    'Today's first {0} day' : ' Today is the {0} day.'
});
