1. Create resource files

Create the folder language under the webapp, add file in it, and name it language.properties, language_en.properties, language_zh_CN.properties. Among them, language.properties is the default resource file.

Add content in it in the following format:

language.properties

welcome=Welcome

language_en.properties

welcome=Welcome

Language_zh_cn.properties

Welcome = U6b22u8fce

Among them, Welcome is key, and this is used in JSP. Properties file Entering Chinese into unicode will be automatically converted into unicode.

Among them, & lt; proprity name = "basenename" value = "/language/language"/& gt; value is the resource file, no suffix name.properties.

3. Call internationalization

3.1 Call internationalization in web

Add

<mvc:interceptors>        <!-- Changes the locale when a 'locale' request parameter is sent; e.g. /?locale=de -->        <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" /></mvc:interceptors><!-- Saves a locale change using a session--><bean id="localeResolver"    class="org.springframework.web.servlet.i18n.SessionLocaleResolver" /><!-- 国际化文件 --><bean id="messageSource"class="org.springframework.context.support.ReloadableResourceBundleMessageSource">    <property name="basename" value="/language/language" />    <property name="defaultEncoding" value="UTF-8"/></bean>

in the jsp file header Change the content at the jsp HTML display content, such as

Copy after login

<a href="javascript:void(0)" class="easyui-linkbutton" data-options="plain:true">    Welcome</a>

changed to

<a href="javascript:void(0)" class="easyui-linkbutton" data-options="plain:true">    <spring:message code="welcome"/></a>

Copy after login

3.2 Call internationalization in javascript

Copy after login

Add

<🎜 in the jsp file header >

Change

<input type="text" value='<spring:message code="welcome"/>' />

Copy after login

in the controller where request is HttpServletRequest and model is Model.

4 Solving Garbled Codes

4.1 Chinese Input Garbled Codes

After completing the above steps, you will find that you enter Chinese in the XCenter interface, click OK, and write Chinese into the database , what is written is garbled code.

if(!model.containsAttribute("contentModel")){    RequestContext requestContext = new RequestContext(request);    String welcome = requestContext.getMessage("welcome");}

Copy after login

The solution is as follows:

In applicationContext.xml, change

Note: Do not add ?useUnicode=true&characterEncoding=UTF-8 after jdbc.url=jdbc:mysql://localhost:3306/demo in jdbc.properties. This is incorrect.

4.2 Some interfaces display Chinese garbled characters

<property name="url" value="${jdbc.url}"/>

Copy after login

Then I found that most interfaces have added this sentence

<%@ page language="java" contentType="text /html; charset=UTF-8" pageEncoding="UTF-8"%>

<property name="url" value="${jdbc.url}?useUnicode=true&amp;characterEncoding=UTF-8"/>

Copy after login

can display Chinese normally, but part of the XCenter interface displays Chinese as???. After inspection, it was found that it is because in the controller The return value is String and marked as @ResponseBody. After checking the information, I found that the default encoding of @ResponseBody in Spring MVC is ISO-8859-1 (others are UTF-8. Does anyone know why another one is used here in the same framework? coding).

Solution:

Add produces ="application/json; charset=utf-8"

< in

🎜> becomes

Then you will find that the Chinese characters in some trees are still displayed as garbled characters. It is found that the return value is converted into JSON format.

@RequestMapping(value = "welcome", method = RequestMethod.POST)

Copy after login

Solution:

Format the return value of tree to

@RequestMapping(value = "welcome", method = RequestMethod.POST, produces = "application/json; charset=utf-8")

Copy after login

5 中英文切换

5.1 资源文件的中英文切换

这个比较简单，使用如下代码就行

<a href="?locale=en" onclick="changeLanguage('en')">English</a><a href="?locale=zh" onclick="changeLanguage('zh_CN')">简体中文</a>

Copy after login

5.2 easyui框架的中英文切换

easyui中有些框架(如datagrid)有些内容是框架自带的，需要在中加入

<script type="text/javascript" src="js/locale/easyui-lang-zh_CN.js"></script>

Copy after login

那如何切换中英文呢

首先不要在中添加上面这句，然后在主界面中加入如下js语句

<script type="text/javascript">    var language=window.navigator.language;    var userLanguage="${sessionScope['org.springframework.web.servlet.i18n.SessionLocaleResolver.LOCALE']}";    if(null != userLanguage&&userLanguage!=""){//not login        language = userLanguage;    }    $(function(){        var src = 'js/locale' + '/easyui-lang-'+language.replace("-","_")+'.js';// when login in China the language=zh-CN             $.getScript(src);    });</script>

Copy after login

这是使用jquery加载js文件。

接下来将项目中需要替换的内容全部用步骤3中的方法替换就行了，这样国际化就完成了。
