springmvc国际化 基于浏览器语言的国际化配置

博客已经迁移至  萌萌的IT人 ，谢谢支持

--------------------------------------------------

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

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>springmvc</servlet-name>

    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

 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
