springmvc国际化 基于浏览器语言的国际化配置

项目结构图如下:

说明:lib下存放的是Spring相关包,项目应用包为Spring3.2,message_*.properties中存放的是国际化的资源文件

资源文件

英语的资源文件message_en.properties

main.title=Hello World

main.target=I love you

韩语的资源文件messages_ko.properties

main.title=\uC548\uB155\uD558\uC2ED\uB2C8\uAE4C

main.target=\uC0AC\uB791\uD574

对应的韩语为：

main.title=안녕하십니까

main.target=사랑해

Spring与spring mvc的相关配置

web.xml文件

 spring-mvc的配置文件servlet-context.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans:beans xmlns="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    

    <!-- Enables the Spring MVC @Controller programming model -->

    <annotation-driven />



    <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <beans:property name="prefix" value="/WEB-INF/views/" />

        <beans:property name="suffix" value=".jsp" />

    </beans:bean>



    <context:component-scan base-package="com.pudp" />

</beans:beans>

spring配置文件spring-context.xml中声明国际化

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    

   

   <context:component-scan base-package="com.pudp" />    

    

   <!-- 定义国际化消息-->   

   <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">   

     

     <!-- 其中basename用来指定properties文件的通用名 如实例中的messages_en.properties,messages_ja.properties通用名都是messages -->

     <property name="basename" value="messages"/>

     <property name="useCodeAsDefaultMessage" value="true" />

     

   </bean>   

    

   <!-- 获取本地 -->  

   <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver"/>  

    

</beans>

说明:servlet-context.xml 只会在servlet做出响应,所以加载信息应该放置在spring配置文件中.

视图层应用

视图层应用前,需要先声明spring标签

<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>

 国际化标签引用

  <body>

      <!-- 使用message 标签配置需要显示的国际化文本, code 对应国际化文件中对应的键的名称 -->

    <span style="color: #2D2D2D;">

        <spring:message code="main.title" />

    </span>

    <br>

    <input type="text" value="<spring:message code="main.target"/>">

  </body>

程序运行结果:

因为我浏览器默认语言是韩语,所以运行结果会展示韩语相关.

更改浏览器默认使用语言.实例中更改为日语,如下图

这时运行程序,系统根据浏览器默认的语言选择日语展示
