Internationalization(I18N) in Spring
almost 10 years ago
Internationalization using MessageSource:- In Spring MVC we can show the LocaleResolver to achieve the Internationlization(I18N) to support the multiple language.
WelcomeController.java
package com.manish.controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; public class WelcomeController extends AbstractController{ @Override protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView model = new ModelAndView("WelcomePage"); return model; } }WelcomePage.jsp
<%@ page contentType="text/html;charset=UTF-8" %> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> <html> <body> <h1>Spring MVC internationalization example</h1> Language : <a href="?language=en">English</a>| <a href="?language=fr">French</a> <h3> welcome.springmvc : <spring:message code="welcome.springmvc" text="default text" /> </h3> Current Locale : ${pageContext.response.locale} </body> </html>app-context.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"> <property name="defaultLocale" value="en" /> </bean> <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"> <property name="paramName" value="language" /> </bean> <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" > <property name="interceptors"> <list> <ref bean="localeChangeInterceptor" /> </list> </property> </bean> <!-- Register the welcome.properties --> <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> <property name="basename" value="welcome" /> </bean> <!-- Register the bean --> <bean class="com.manish.controller.WelcomeController" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" > <property name="prefix"> <value>/WEB-INF/pages/</value> </property> <property name="suffix"> <value>.jsp</value> </property> </bean> </beans>welcome_fr.properties
welcome.springmvc = Bonjour tout le monde partir du printemps
welcome.properties
welcome.springmvc = Hello world from spring
In above example we can achieve I18N using the two properties file( welcome_fr.properties,welcome.properties) the welcome.properties can contain the message in english that is default locale and welcome_fr.properties can contain the same message in france language
