java系统国际化的配置

本代码来源于开源MyExam系统

首先写好资源文件:

message_en_US.properties

等等

springmvc-servlet.xml文件

<!-- 国际化操作拦截器  -->

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

<propertyname="basename"value="message"/>

<propertyname="useCodeAsDefaultMessage"value="true"/>

</bean>

  <beanid="localeChangeInterceptor"class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">

  

    <propertyname="paramName"value="siteLanguage"/>

 </bean>


 <beanid="localeResolver"class="org.springframework.web.servlet.i18n.SessionLocaleResolver"/>

 

<beanclass="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"p:order="1">

     <propertyname="interceptors"ref="localeChangeInterceptor"/>

</bean>

<beanclass="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"p:order="2">

     <propertyname="interceptors"ref="localeChangeInterceptor"/>

   </bean>

说明:该文件配置了springmvc自带的动态国际化,可以去网站搜索相关更多的信息,下面配置js文件国际化,加载个过滤器

Web.xml文件

<filter>

        <filter-name>I18nFilter</filter-name>

        <filter-class>com.exam.filter.I18nFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>I18nFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>解析说明:

com.exam.filter.I18nFilte类代码:

      package com.exam.util;

 

import java.io.IOException;

import java.io.InputStream;

import java.util.ArrayList;

import java.util.Enumeration;

import java.util.Properties;

 

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpSession;

 

import org.springframework.context.support.ResourceBundleMessageSource;

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.i18n.SessionLocaleResolver;

import org.springframework.web.servlet.mvc.AbstractController;

 

public classI18n extendsAbstractController{

protected ModelAndView handleRequestInternal(HttpServletRequestarg0,HttpServletResponse arg1)throwsIOException, IllegalArgumentException, IllegalAccessException{

    Propertiesprop = newProperties();

    InputStreamin = getClass().getResourceAsStream("/message_en_US.properties");

    prop.load(in);

 

    ArrayList<String>i18nList=newArrayList<String>();

 

    Enumeration<String>enu =(Enumeration<String>)prop.propertyNames()

    while (enu.hasMoreElements()){

        Stringkey = enu.nextElement();

        i18nList.add(key);

    }

    HttpSessionsession =arg0.getSession();

    session.setAttribute("i18nList",i18nList);

 

   

 

    ModelAndViewmodel=newModelAndView();

    //model.addObject("i18nList",i18nList);

    return model;

 

 

}

}

header.jsp

<div style="display:none" id="i18nDiv">
<c:forEach var="i18n" items="${i18n}" varStatus="step">
<input id="${i18n}" name="${i18n}" value="<fmt:message key="${i18n}"/>"/>
</c:forEach>
</div>

前台使用

1.      jsp页面用jstl国际化标签输出:<fmt:messagekey="system.site"/>

2.      js文件:$(“# system.site”).val()

大家可以下载源代码,慢慢研究吧
