SpringMvc多语言配置

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>
