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

Important things to note are as follows:

• <property name="defaultLocale" value="en" />: By default, en locale is used.
• <mvc:interceptors>: LocaleChangeInterceptor is configured as a HandlerInterceptor. It would intercept all the handler requests and check for the locale.
• <property name="paramName" value="language" />: LocaleChangeInterceptor is configured to use a request param 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.
