How to achieve localization in Spring MVC applications?

Ref:- http://howtodoinjava.com/2015/03/02/spring-mvc-interview-questions-with-answers/

Spring framework is shipped with LocaleResolver to support the internationalization and thus localization as well. To make Spring MVC application supports the internationalization, you will need to register two beans.

1) SessionLocaleResolver : It resolves locales by inspecting a predefined attribute in a user’s session. If the session attribute doesn’t exist, this locale resolver determines the default locale from the accept-language HTTP header.

<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">     <property name="defaultLocale" value="en" /> </bean>

2) LocaleChangeInterceptor : This interceptor detects if a special parameter is present in the current HTTP request. The parameter name can be customized with the paramName property of this interceptor. If such a parameter is present in the current request, this interceptor changes the user’s locale according to the parameter value.

<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">     <property name="paramName" value="lang" /> </bean>   <!-- Enable the interceptor --> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">     <property name="interceptors">         <list>             <ref bean="localeChangeInterceptor" />         </list>     </property> </bean>

Next step is to have each locale specific properties file having texts in that locale specific language e.g.messages.properties and messages_zh_CN.properties etc.
