所謂國際化就是支持多種語言,web應(yīng)用在不同的瀏覽環(huán)境中可以顯示出不同的語言,比如說漢語、英語等。下面我將以具體的實(shí)例來舉例說明:
(1)新建動(dòng)態(tài)Java web項(xiàng)目,并導(dǎo)入幾個(gè)SpringMVC必需的幾個(gè)jar包,項(xiàng)目結(jié)構(gòu)圖和所需jar包如下:
(2)配置web.xml:

常規(guī)配置,沒有什么特殊的地方,不多解釋

<? 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中定義的注解 --> < mvc:annotation-driven /> <!-- 視圖相關(guān)配置 --> < bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver" > < property name = "prefix" value = "/WEB-INF/pages/" /> <!-- 視圖前綴 --> < property name = "suffix" value = ".jsp" /> <!-- 視圖后綴 --> </ bean > <!-- 存儲(chǔ)區(qū)域設(shè)置信息 --> < bean id = "localeResolver" <!-- 國際化資源文件 --> < 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類通過一個(gè)預(yù)定義會(huì)話名將區(qū)域化信息存儲(chǔ)在會(huì)話中。緊接著的“messageSource”配置的是國際化資源文件的路徑,”classpath:messages”指的是classpath路徑下的messages_zh_CN.properties文件和messages_en_US.properties文件。在這個(gè)配置文件的最后配置的是一個(gè)攔截器,該攔截器通過名為”lang”的參數(shù)來攔截HTTP請(qǐng)求,使其重新設(shè)置頁面的區(qū)域化信息
(4)兩個(gè)國際化資源文件:
i)messages_zh_CN.properties文件:
1

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:
1
2
3

|
language.cn = Chinese language.en = English internationalisation = \u0020Internationalisation welcome = Welcome to visit "zifangsky's personal blog",URL\uff1ahttp://www.zifangsky.cn |
注:上面一些看起來“亂碼”的地方實(shí)際上是經(jīng)過Unicode編碼的
(5)后臺(tái)處理請(qǐng)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; } } |
這個(gè)controller很簡單,就是轉(zhuǎn)到一個(gè)視圖頁面welcome.jsp
(6)首頁的index.jsp:
1
|
<% response.sendRedirect( "hello.html" ); %> |
意思很簡單,就是項(xiàng)目啟動(dòng)之后就請(qǐng)求htllo.html,也就是讓controller中的welcome方法處理這個(gè)請(qǐng)求
(7)welcome.jsp:
1

<%@ 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,在需要使用國際化處理的地方都使用了spring的message標(biāo)簽,code屬性對(duì)應(yīng)資源文件中的“鍵”名稱
(8)最后的顯示效果如下:
i)中文:
ii)英文:
以上就是本文的全部內(nèi)容,希望對(duì)大家的學(xué)習(xí)有所幫助,也希望大家多多支持服務(wù)器之家。
