There are two parts to configuring SessionLocaleResolver. The first one is to configure a localeResolver bean. The second one is to configure an interceptor to handle the change in the locale:

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

    <mvc:interceptors> 
      <bean id="springMVCLocaleChangeInterceptor" 
                   class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"> 
        <property name="paramName" value="language" /> 
      </bean>
    </mvc:interceptors>

The following definitions explain the workings of the preceding code block:

• <property name="defaultLocale" value="en" />: By default, the en locale is used.
• <mvc:interceptors>: LocaleChangeInterceptor is configured as a HandlerInterceptor. It would intercept all of the handler requests and check for the locale.
• <property name="paramName" value="language" />: LocaleChangeInterceptor is configured to use a request parameter name called language to indicate the locale. So, any URL of the http://server/uri?language={locale} format would trigger a change in the locale.
• If you append language=en to any URL, you would be using en locale for the duration of the session. If you append language=fr to any URL, then you would be using a French locale.
