  • I18N国际化

    一、在spring.xml中配置

     1 <beans xmlns="http://www.springframework.org/schema/beans"
 2  xmlns:context="http://www.springframework.org/schema/context"
 3  xmlns:p="http://www.springframework.org/schema/p"
 4  xmlns:mvc="http://www.springframework.org/schema/mvc"
 5  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 6  xsi:schemaLocation="http://www.springframework.org/schema/beans
 7       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
 8       http://www.springframework.org/schema/context
 9       http://www.springframework.org/schema/context/spring-context.xsd
10       http://www.springframework.org/schema/mvc
11       http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
12      <!-- 启动注解驱动的Spring MVC功能，注册请求url和注解POJO类方法的映射-->
13      <mvc:annotation-driven />
14      <!-- 启动包扫描功能，以便注册带有@Controller、@Service、@repository、@Component等注解的类成为spring的bean -->
15      <context:component-scan base-package="com.**.**" />
16      <!-- 对模型视图名称的解析，在请求时模型视图名称添加前后缀 -->
17      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/" p:suffix=".jsp" />
18     
19     <!-- 根据浏览器语言判断start -->
20    <!--  <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource" p:basename="i18n/messages"/> -->
21      <!-- 根据浏览器语言判断end -->
22     <!-- ******************************************************************************** --> 
23      <!-- 根据session判断start -->
24     <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource" p:basename="i18n/messages"/>
25     <mvc:interceptors>  
26         <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />  
27     </mvc:interceptors>  
28     <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver" />
29      <!-- 根据session判断end -->
30      <!-- ******************************************************************************** --> 
31      <!-- 根据cookie判断start -->
32 <!--      <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource" p:basename="i18n/messages"/>
33     <mvc:interceptors>  
34         <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />  
35     </mvc:interceptors>  
36     <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" /> -->
37      <!-- 根据cookie判断end -->
38      <!-- ******************************************************************************** --> 
39 
40 </beans>
    View Code

    二、创建三个jsp页面

    　　1.根据cookie判断language_cookie.jsp　　

     1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2     pageEncoding="UTF-8"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 
 5 <%@taglib prefix="spring" uri="http://www.springframework.org/tags" %>
 6 
 7 <html>
 8 <head>
 9 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
10 <title>Insert title here</title>
11 </head>
12 <body>
13 <a href="language_cookie?langType=zh">中文</a> | <a href="language_cookie?langType=en">英文</a><br/>
14     下面展示的是后台获取的国际化信息：<br/>
15     ${text}<br/>
16 
17     页面获取信息：<br/>
18     <spring:message code="text"/>  <br/>
19     Locale: ${pageContext.response.locale }
20 </body>
21 </html>
    View Code

     　　2.根据浏览器当前语言判断language_liulanqi.jsp

     1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2     pageEncoding="UTF-8"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 
 5 <%@taglib prefix="spring" uri="http://www.springframework.org/tags" %>
 6 
 7 <html>
 8 <head>
 9 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
10 <title>根据浏览器语言获取</title>
11 </head>
12 <body>
13     后台获取的国际化信息：<br/>
14     ${text}<br/>
15 
16     页面获取信息：<br/>
17     <spring:message code="text"/>  <br/>
18     Locale: ${pageContext.response.locale }
19 </body>
20 </html>
    View Code

    　　3.根据session判断language_session.jsp

     1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2     pageEncoding="UTF-8"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 
 5 <%@taglib prefix="spring" uri="http://www.springframework.org/tags" %>
 6 
 7 <html>
 8 <head>
 9 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
10 <title>Insert title here</title>
11 </head>
12 <body>
13 <a href="language_session?langType=zh">中文</a> | <a href="language_session?langType=en">英文</a><br/>
14     下面展示的是后台获取的国际化信息：<br/>
15     ${text}<br/>
16 
17     页面获取信息：<br/>
18     <spring:message code="text"/>  <br/>
19     Locale: ${pageContext.response.locale }
20 </body>
21 </html>
    View Code

     三、配置测试类GlobalController.java

     1 package com.sh.test;
 2 
 3 
 4 import java.util.Locale;
 5 
 6 import javax.servlet.http.HttpServletRequest;
 7 import javax.servlet.http.HttpServletResponse;
 8 
 9 import org.springframework.context.i18n.LocaleContextHolder;
10 import org.springframework.stereotype.Controller;
11 import org.springframework.web.bind.annotation.RequestMapping;
12 import org.springframework.web.bind.annotation.RequestMethod;
13 import org.springframework.web.bind.annotation.RequestParam;
14 import org.springframework.web.servlet.ModelAndView;
15 import org.springframework.web.servlet.i18n.CookieLocaleResolver;
16 import org.springframework.web.servlet.i18n.SessionLocaleResolver;
17 import org.springframework.web.servlet.support.RequestContext;
18 /**
19  * 需在spring-servlet.xml中开启对应的配置才能生效
20  * @author Administrator
21  *
22  */
23 @Controller
24 public class GlobalController {
25     
26 
27     
28     /**
29      * 根据浏览器语言判断
30      * @param request
31      * @param response
32      * @param langType
33      * @return
34      */
35     @RequestMapping(value="/language_liulanqi", method = {RequestMethod.GET})
36     public ModelAndView test(HttpServletRequest request,HttpServletResponse response){
37             //从后台代码获取国际化信息
38             RequestContext requestContext = new RequestContext(request);
39             request.setAttribute("text",requestContext.getMessage("text"));
40         return new ModelAndView("/i18n/language_liulanqi");
41     }
42     /**
43      * 根据session判断
44      * @param request
45      * @param response    
46      * @param langType
47      * @return
48      */
49     @RequestMapping(value="/language_session", method = {RequestMethod.GET})
50     public ModelAndView test1(HttpServletRequest request,HttpServletResponse response, @RequestParam(value="langType", defaultValue="zh") String langType){
51          request.getSession().removeAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME); 
52         if(langType.equals("zh")){
53              Locale locale = new Locale("zh", "CN"); 
54              request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale); 
55          }
56          else if(langType.equals("en")){
57              Locale locale = new Locale("en", "US"); 
58              request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale);
59          }else{ 
60              request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,LocaleContextHolder.getLocale());
61          }
62         //从后台代码获取国际化信息
63         RequestContext requestContext = new RequestContext(request);
64         String message = requestContext.getMessage("text");
65         request.setAttribute("text",message);
66         return new ModelAndView("/i18n/language_session");
67     }
68     /**
69      * 根据cookie判断
70      * @param request
71      * @param response
72      * @param langType
73      * @return
74      */
75     @RequestMapping(value="/language_cookie", method = {RequestMethod.GET})
76     public ModelAndView test2(HttpServletRequest request,HttpServletResponse response, @RequestParam(value="langType", defaultValue="zh") String langType){
77         if(langType.equals("zh")){
78             Locale locale = new Locale("zh", "CN"); 
79             (new CookieLocaleResolver()).setLocale (request, response, locale);
80         }else if(langType.equals("en")){
81             Locale locale = new Locale("en", "US"); 
82             (new CookieLocaleResolver()).setLocale (request, response, locale);
83         }else{
84             (new CookieLocaleResolver()).setLocale (request, response, LocaleContextHolder.getLocale());
85         }
86         //从后台代码获取国际化信息
87         RequestContext requestContext = new RequestContext(request);
88         request.setAttribute("text",requestContext.getMessage("text"));
89         return new ModelAndView("/i18n/language_cookie");
90     }
91     
92 }
    View Code

    五、在src下创建i18n配置文件，

    messages_en_US.properties

    　　text=English2

    messages_zh_CN.properties

    　　text=中文

    messages.properties

    　　text=默认

     六、使用方式

    　　1.根据浏览器语言选择，需要打开配置文件中的对应配置，开启此模式后只能通过修改浏览器首选语言切换

    　　http://192.168.1.168:8080/i18ntest/language_liulanqi

    　　2.根据session选择，开启对应配置，通过URL参数切换语言

    　　http://192.168.1.168:8080/i18ntest/language_session?langType=zh

    　　3.根据cookie选择，开启对应配置，通过URL参数切换语言

    　　http://192.168.1.168:8080/i18ntest/language_cookie?langType=en
