参考：http://shihuan830619.iteye.com/blog/2003903

applicationContext.xml文件中加入如下代码:

Java代码  
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">  
        <property name="basenames">    
            <list>  
                <value>messages</value>  
            </list>    
        </property>  
          
        <!-- 这个是配置单一路径的做法,也好用  
        <property name="basename">  
            <value>messages</value>  
        </property>  
         -->  
          
        <property name="defaultEncoding" value="UTF-8" />  
    </bean>  
      
      
    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">  
        <property name="cookieName" value="clientlanguage"/>  
        <property name="cookieMaxAge" value="94608000"/>  
        <property name="defaultLocale" value="en" />  
    </bean>  

spring-servlet.xml文件加入如下代码:

Java代码  
<context:component-scan base-package="com.easeye.ymail.web.eventmail.appbusiness.multilanguage.control"/>  
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">  
        <property name="paramName" value="language" />  
    </bean>  

messages_en.properties文件加入如下代码:

Java代码  
contact.mytestkey=hello\!  

messages_zh.properties文件加入如下代码:

Java代码  
contact.mytestkey=\u60A8\u597D\!  

web.xml文件加入如下代码:

Java代码  
<filter>  
        <filter-name>systemLanguageFilter</filter-name>  
        <filter-class>com.easeye.ymail.web.webcore.lang.SystemLanguageFilter</filter-class>  
    </filter>  
    <filter-mapping>  
        <filter-name>systemLanguageFilter</filter-name>  
        <url-pattern>*.do</url-pattern>  
    </filter-mapping>  
    <filter-mapping>  
        <filter-name>systemLanguageFilter</filter-name>  
        <url-pattern>*.jsp</url-pattern>  
    </filter-mapping>  

SystemLanguageFilter.java代码如下:

Java代码  
import java.io.IOException;  
import java.util.Locale;  
  
import javax.servlet.Filter;  
import javax.servlet.FilterChain;  
import javax.servlet.FilterConfig;  
import javax.servlet.ServletException;  
import javax.servlet.ServletRequest;  
import javax.servlet.ServletResponse;  
import javax.servlet.http.HttpServletRequest;  
  
import org.springframework.web.servlet.DispatcherServlet;  
import org.springframework.web.servlet.support.RequestContextUtils;  
  
import com.easeye.ymail.web.webcore.utils.SpringUtil;  
  
  
public class SystemLanguageFilter implements Filter {  
  
    @Override  
    public void init(FilterConfig filterConfig) throws ServletException {  
  
    }  
  
    @Override  
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {  
        request.setAttribute(DispatcherServlet.LOCALE_RESOLVER_ATTRIBUTE, SpringUtil.getBean(org.springframework.web.servlet.i18n.CookieLocaleResolver.class));  
        Locale locale = RequestContextUtils.getLocale((HttpServletRequest) request);  
        request.setAttribute("easeyeI18nLang", locale.getLanguage());  
        chain.doFilter(request, response);  
    }  
  
    @Override  
    public void destroy() {  
    }  
  
}  

ChangeLanguageControl.java代码如下:

Java代码  
import java.util.Locale;  
  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
  
import org.slf4j.Logger;  
import org.slf4j.LoggerFactory;  
import org.springframework.beans.propertyeditors.LocaleEditor;  
import org.springframework.stereotype.Controller;  
import org.springframework.util.StringUtils;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.RequestMethod;  
import org.springframework.web.bind.annotation.ResponseBody;  
import org.springframework.web.servlet.LocaleResolver;  
import org.springframework.web.servlet.support.RequestContextUtils;  
  
import com.easeye.ymail.web.webcore.messaging.OpMessage;  
  
/**功能: 动态改变系统的语言*/  
@Controller  
@RequestMapping("/")  
public class ChangeLanguageControl {  
  
protected Logger logger = LoggerFactory.getLogger(getClass().getName());  
  
@RequestMapping(value = "changelanguage.do")  
public String changeLanguage(HttpServletRequest request, HttpServletResponse response) {  
return "redirect:" + request.getParameter("originalUrl");  
}  
  
}  

easeye-en.js文件加入如下代码(注意引用顺序一定是先引用easeye-en.js后引用easeye-ch.js):

Java代码  
var easeyeI18n={};  
easeyeI18n["en"] = {  
"contactName" : "contact name",  
"userName" : "user name"  
}  

easeye-ch.js文件加入如下代码:

Java代码  
easeyeI18n["ch"] = {  
"contactName" : "联系人姓名",  
"userName" : "用户帐号"  
}  

mybusiness.js文件加入如下代码:

Java代码  
function getEaseyeI18nText(langKey){  
return easeyeI18n[easeyeI18nLang][langKey];  
}  
function switchLanguage(language){  
if(window.location.href.indexOf(".do")==-1){  
open("/eventmail/changelanguage.do?language="+language+"&originalUrl="+encodeURI(window.location.href),"_self");  
}else{  
if(window.location.href.indexOf(".do?")==-1){  
open("?language="+language,"_self");  
}else{  
open("&language="+language,"_self");  
}  
}  
}  

在login.jsp文件中代码如下:

Java代码  
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>  
  
<font color="red">  
                                                                    mytestkey: <spring:message code="contact.mytestkey"  />  
                                                                    Current Locale : ${pageContext.response.locale}  
                                                                    </font>  
  
<a href="${ctx}/changelanguage.do?language=en">EN</a>  
                                                                    <a href="${ctx}/changelanguage.do?language=zh_CN">CN</a>
