国际化------international
1、配置web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>springmvc_fileupload</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> </web-app>
2、配置springmvc-servlet.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:c="http://www.springframework.org/schema/c" xmlns:cache="http://www.springframework.org/schema/cache" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> <context:component-scan base-package="com.wh.handler"></context:component-scan> <context:annotation-config /> <!--激活Bean中定义的注解 --> <mvc:annotation-driven /> <!-- 配置国际化文件 --> <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> </beans>
3、编写index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'index.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> </head> <body> <!-- ${pageContext.request.contextPath} 这个是比较重要的,否则路径老是不对 --> <form action="${pageContext.request.contextPath}/intern.action" method="get"> <input type="text" name="un" value="xxx"/> <br/> <input type="submit" value="提交"/> <br/> </form> </body> </html>
4、编写handler.java
package com.wh.handler; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.support.RequestContext; @Controller public class InternationHandler { @RequestMapping("intern.action") public String demo(HttpServletRequest request){ System.out.print("后台国际化:"); //后台代码中通过RequestContext对象的getMessage方法获取国际化信息 RequestContext requestContext = new RequestContext(request); String msg = requestContext.getMessage("uname"); System.out.println("msg:"+msg); return "hello.jsp"; } }
5、编写hello.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>My JSP 'index.jsp' starting page</title> </head> <body> <!-- 浏览器问题,有的浏览器不支持国际化,比如360浏览器 --> 前端国际化 <br> <spring:message code="uname"></spring:message> </body> </html>
6、配置国际化文件
messages_zh_CN.properties、messages_en_US.properties、messages_ja_JP.properties、messages.properties
注意:要先从index页面,经过后台处理,再到前台hello页面才行,同时,要注意浏览器问题,一个浏览器不支持国际化,试试其他浏览器。
