spring internationalization with CookieResolve

 本文简单介绍下如何利用spring3.0 改变cookie来进行国际化，当然spring国际化有几种方式，本文只是简单使用cookie这种方式，配置的大致代码如下：

  

applicationcontext.xml

 

<bean id="messageSource"

class="org.springframework.context.support.ResourceBundleMessageSource">

<property name="basename">

<value>message</value>

</property>

</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="zh" />

</bean>

 

messageSource 这个主要是加载国际化文件和配置文件的前缀，CookieLocaleResolver这个主要是用来配置cookie存活时间和默认显示。

 

下面是配置文件名称的格式

resource files

message_en.properties

message_zh.properties

 

  控制改变cookie code:

 

package com.softterk.controller.front;

 

import java.util.Locale;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

 

import org.apache.log4j.Logger;

import org.springframework.beans.propertyeditors.LocaleEditor;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.servlet.LocaleResolver;

import org.springframework.web.servlet.support.RequestContext;

import org.springframework.web.servlet.support.RequestContextUtils;

 

import com.softterk.util.AjaxUtil;

 

@Controller

public class ChangeLanguageController {

 

   private static Logger LOG =Logger.getLogger(ChangeLanguageController.class);

   

   @RequestMapping(value="/changelanguage",method=RequestMethod.POST)

   public void changelanguage(@RequestParam String new_lang,HttpServletResponse response,HttpServletRequest request)

   {

  LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(request);

  if (localeResolver == null) {  

    LOG.error("No LocaleResolver found: not in a DispatcherServlet request?");

    throw new IllegalStateException("No LocaleResolver found: not in a DispatcherServlet request?");  

}

 

  LocaleEditor localeEditor = new LocaleEditor();

  localeEditor.setAsText(new_lang);

  localeResolver.setLocale(request, response, (Locale)localeEditor.getValue());  

  RequestContext requestContext = new RequestContext(request);

  Locale locale = requestContext.getLocale();

  request.setAttribute("locale", locale.toString());   

  if(LOG.isDebugEnabled())

    LOG.debug("locale=="+locale.toString());

    AjaxUtil.backData(response, "1");

   }

}

 

 

jsp page:这里写的是一个js 方法，用来动态改变。

 

function changeLanguage(language)

   {

       $.ajax({

           type: "POST",

           url: "<%=path%>/changelanguage",

           data: "new_lang="+language,

           dataType:"text",

           async: true,

           error: function(data, error) {

          alert("error!please try it again soon");

          },

          success: function(data)

          {

             window.location.reload();

          }

      });

   }

 

获得配置文件的内容的话，就直接使用jstl的fmt和spring的标签都可以获得。
