所谓国际化就是支持多种语言,web应用在不同的浏览环境中可以显示出不同的语言,比如说汉语、英语等。下面我将以具体的实例来举例说明:
(1)新建动态Java web项目,并导入几个SpringMVC必需的几个jar包,项目结构图和所需jar包如下:
(2)配置web.xml:

常规配置,没有什么特殊的地方,不多解释
(3)SpringMVC的配置文件springmvc-servlet.xml:

<? 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:context = "http://www.springframework.org/schema/context" xmlns:mvc = "http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> < context:component-scan base-package = "cn.zifangsky.* *.controller" /> < context:annotation-config /> <!-- 激活Bean中定义的注解 --> < mvc:annotation-driven /> <!-- 视图相关配置 --> < bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver" > < property name = "prefix" value = "/WEB-INF/pages/" /> <!-- 视图前缀 --> < property name = "suffix" value = ".jsp" /> <!-- 视图后缀 --> </ bean > <!-- 存储区域设置信息 --> < bean id = "localeResolver" <!-- 国际化资源文件 --> < bean id = "messageSource" class = "org.springframework.context.support.ReloadableResourceBundleMessageSource" > < property name = "basename" value = "classpath:messages" /> </ bean > < mvc:interceptors > < bean id = "localeChangeInterceptor" class = "org.springframework.web.servlet.i18n.LocaleChangeInterceptor" > < property name = "paramName" value = "lang" /> </ bean > </ mvc:interceptors > </ beans > |
在上面的配置中,SessionLocaleResolver类通过一个预定义会话名将区域化信息存储在会话中。紧接着的“messageSource”配置的是国际化资源文件的路径,”classpath:messages”指的是classpath路径下的messages_zh_CN.properties文件和messages_en_US.properties文件。在这个配置文件的最后配置的是一个拦截器,该拦截器通过名为”lang”的参数来拦截HTTP请求,使其重新设置页面的区域化信息
(4)两个国际化资源文件:
i)messages_zh_CN.properties文件:

language.cn = \u4e2d\u6587 language.en = \u82f1\u6587 internationalisation = \u56fd\u9645\u5316 welcome = \u6b22\u8fce\u8bbf\u95ee\u201c\u007a\u0069\u0066\u0061\u006e\u0067\u0073\u006b\u0079\u7684\u4e2a\u4eba\u535a\u5ba2\u201d\uff0c\u0055\u0052\u004c\uff1a\u0068\u0074\u0074\u0070\u003a\u002f\u002f\u0077\u0077\u0077\u002e\u007a\u0069\u0066\u0061\u006e\u0067\u0073\u006b\u0079\u002e\u0063\u006e |
ii)messages_en_US.properties文件:

language.cn = Chinese language.en = English internationalisation = \u0020Internationalisation welcome = Welcome to visit "zifangsky's personal blog",URL\uff1ahttp://www.zifangsky.cn |
注:上面一些看起来“乱码”的地方实际上是经过Unicode编码的
(5)后台处理请求的controller:

package cn.zifangsky.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; @Controller public class I18nController { @RequestMapping (value = "/hello" ) public ModelAndView welcome() { ModelAndView modelAndView = new ModelAndView( "welcome" ); return modelAndView; } } |
这个controller很简单,就是转到一个视图页面welcome.jsp
(6)首页的index.jsp:
1
|
<% response.sendRedirect( "hello.html" ); %> |
意思很简单,就是项目启动之后就请求htllo.html,也就是让controller中的welcome方法处理这个请求
(7)welcome.jsp:

<%@ page language= "java" contentType= "text/html; charset=UTF-8" pageEncoding= "UTF-8" %> <% @taglib prefix= "mvc" uri= "http://www.springframework.org/tags/form" %> <% @taglib prefix= "spring" uri= "http://www.springframework.org/tags" %> <html> <head> <title>SpringMVC<spring:message code= "internationalisation" /></title> </head> <body> Language: <a href= "?lang=zh_CN" rel= "external nofollow" ><spring:message code= "language.cn" /></a> - <a href= "?lang=en_US" rel= "external nofollow" ><spring:message code= "language.en" /></a> <h2> <spring:message code= "welcome" /> </h2> Locale: ${pageContext.response.locale } </body> </html> |
可以看出,在需要使用国际化处理的地方都使用了spring的message标签,code属性对应资源文件中的“键”名称
(8)最后的显示效果如下:
i)中文:
ii)英文:
