在系列(7)中我们讲了数据的格式化显示,Spring在做格式化展示的时候已经做了国际化处理,那么如何将我们网站的其它内容(如菜单、标题等)做国际化处理呢?这就是本篇要将的内容—>国际化。
一.基于浏览器请求的国际化实现:
首先配置我们项目的springservlet-config.xml文件添加的内容如下:
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> <!-- 国际化信息所在的文件名 --> <property name="basename" value="messages" /> <!-- 如果在国际化资源文件中找不到对应代码的信息,就用这个代码作为名称 --> <property name="useCodeAsDefaultMessage" value="true" /> </bean>
在com.demo.web.controllers包中添加GlobalController.java内容如下:
package com.demo.web.controllers; import java.util.Date; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.support.RequestContext; import com.demo.web.models.FormatModel; @Controller @RequestMapping(value = "/global") public class GlobalController { @RequestMapping(value="/test", method = {RequestMethod.GET}) public String test(HttpServletRequest request,Model model){ if(!model.containsAttribute("contentModel")){ //从后台代码获取国际化信息 RequestContext requestContext = new RequestContext(request); model.addAttribute("money", requestContext.getMessage("money")); model.addAttribute("date", requestContext.getMessage("date")); FormatModel formatModel=new FormatModel(); formatModel.setMoney(12345.678); formatModel.setDate(new Date()); model.addAttribute("contentModel", formatModel); } return "globaltest"; } }
这里展示模型还用系列(7)中的作为演示。
在项目中的源文件夹resources中添加messages.properties、messages_zh_CN.properties、messages_en_US.properties三个文件,其中messages.properties、messages_zh_CN.properties里面的"money", "date",为中文,messages_en_US.properties里面的为英文。
在views文件夹中添加globaltest.jsp视图,内容如下:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@taglib prefix="spring" uri="http://www.springframework.org/tags" %> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> 下面展示的是后台获取的国际化信息:<br/> ${money}<br/> ${date}<br/> 下面展示的是视图中直接绑定的国际化信息:<br/> <spring:message code="money"/>:<br/> <spring:eval expression="contentModel.money"></spring:eval><br/> <spring:message code="date"/>:<br/> <spring:eval expression="contentModel.date"></spring:eval><br/> </body> </html>
运行测试:
更改浏览器语言顺序,刷新页面:
二.基于Session的国际化实现:
在项目的springservlet-config.xml文件添加的内容如下(第一种时添加的内容要保留):
<mvc:interceptors> <!-- 国际化操作拦截器 如果采用基于(请求/Session/Cookie)则必需配置 --> <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" /> </mvc:interceptors> <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver" />
更改globaltest.jsp视图为如下内容:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@taglib prefix="spring" uri="http://www.springframework.org/tags" %> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <a href="test?langType=zh">中文</a> | <a href="test?langType=en">英文</a><br/> 下面展示的是后台获取的国际化信息:<br/> ${money}<br/> ${date}<br/> 下面展示的是视图中直接绑定的国际化信息:<br/> <spring:message code="money"/>:<br/> <spring:eval expression="contentModel.money"></spring:eval><br/> <spring:message code="date"/>:<br/> <spring:eval expression="contentModel.date"></spring:eval><br/> </body> </html>
更改GlobalController.java为如下内容:
package com.demo.web.controllers; import java.util.Date; import java.util.Locale; import javax.servlet.http.HttpServletRequest; import org.springframework.context.i18n.LocaleContextHolder; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; 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.i18n.SessionLocaleResolver; import org.springframework.web.servlet.support.RequestContext; import com.demo.web.models.FormatModel; @Controller @RequestMapping(value = "/global") public class GlobalController { @RequestMapping(value="/test", method = {RequestMethod.GET}) public String test(HttpServletRequest request,Model model, @RequestParam(value="langType", defaultValue="zh") String langType){ if(!model.containsAttribute("contentModel")){ if(langType.equals("zh")){ Locale locale = new Locale("zh", "CN"); request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale); } else if(langType.equals("en")){ Locale locale = new Locale("en", "US"); request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale); } else request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,LocaleContextHolder.getLocale()); //从后台代码获取国际化信息 RequestContext requestContext = new RequestContext(request); model.addAttribute("money", requestContext.getMessage("money")); model.addAttribute("date", requestContext.getMessage("date")); FormatModel formatModel=new FormatModel(); formatModel.setMoney(12345.678); formatModel.setDate(new Date()); model.addAttribute("contentModel", formatModel); } return "globaltest"; } }
运行测试:
三.基于Cookie的国际化实现:
把实现第二种方法时在项目的springservlet-config.xml文件中添加的
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver" />
注释掉,并添加以下内容:
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" />
更改GlobalController.java为如下内容:
package com.demo.web.controllers; import java.util.Date; import java.util.Locale; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.context.i18n.LocaleContextHolder; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; 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.i18n.CookieLocaleResolver; //import org.springframework.web.servlet.i18n.SessionLocaleResolver; import org.springframework.web.servlet.support.RequestContext; import com.demo.web.models.FormatModel; @Controller @RequestMapping(value = "/global") public class GlobalController { @RequestMapping(value="/test", method = {RequestMethod.GET}) public String test(HttpServletRequest request, HttpServletResponse response, Model model, @RequestParam(value="langType", defaultValue="zh") String langType){ if(!model.containsAttribute("contentModel")){ /*if(langType.equals("zh")){ Locale locale = new Locale("zh", "CN"); request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale); } else if(langType.equals("en")){ Locale locale = new Locale("en", "US"); request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale); } else request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,LocaleContextHolder.getLocale());*/ if(langType.equals("zh")){ Locale locale = new Locale("zh", "CN"); //request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale); (new CookieLocaleResolver()).setLocale (request, response, locale); } else if(langType.equals("en")){ Locale locale = new Locale("en", "US"); //request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale); (new CookieLocaleResolver()).setLocale (request, response, locale); } else //request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,LocaleContextHolder.getLocale()); (new CookieLocaleResolver()).setLocale (request, response, LocaleContextHolder.getLocale()); //从后台代码获取国际化信息 RequestContext requestContext = new RequestContext(request); model.addAttribute("money", requestContext.getMessage("money")); model.addAttribute("date", requestContext.getMessage("date")); FormatModel formatModel=new FormatModel(); formatModel.setMoney(12345.678); formatModel.setDate(new Date()); model.addAttribute("contentModel", formatModel); } return "globaltest"; } }
运行测试:
关于<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" />3个属性的说明(可以都不设置而用其默认值):
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver"> <!-- 设置cookieName名称,可以根据名称通过js来修改设置,也可以像上面演示的那样修改设置,默认的名称为 类名+LOCALE(即:org.springframework.web.servlet.i18n.CookieLocaleResolver.LOCALE--> <property name="cookieName" value="lang"/> <!-- 设置最大有效时间,如果是-1,则不存储,浏览器关闭后即失效,默认为Integer.MAX_INT--> <property name="cookieMaxAge" value="100000"> <!-- 设置cookie可见的地址,默认是“/”即对网站所有地址都是可见的,如果设为其它地址,则只有该地址或其后的地址才可见--> <property name="cookiePath" value="/"> </bean>
四.基于URL请求的国际化的实现:
首先添加一个类,内容如下:
import java.util.Locale; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.DispatcherServlet; import org.springframework.web.servlet.LocaleResolver; public class MyAcceptHeaderLocaleResolver extends AcceptHeaderLocaleResolver { private Locale myLocal; public Locale resolveLocale(HttpServletRequest request) { return myLocal; } public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) { myLocal = locale; } }
然后把实现第二种方法时在项目的springservlet-config.xml文件中添加的
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver" />
注释掉,并添加以下内容:
<bean id="localeResolver" class="xx.xxx.xxx.MyAcceptHeaderLocaleResolver"/>
“xx.xxx.xxx”是刚才添加的MyAcceptHeaderLocaleResolver 类所在的包名。
保存之后就可以在请求的URL后附上 locale=zh_CN 或 locale=en_US 如 http://xxxxxxxx?locale=zh_CN 来改变语言了,具体这里不再做演示了。
国际化部分的内容到此结束。
