If i will try to access to the http://localhost:8080/index.htlm directly - it's set default Locale. For the SessionLocaleResolver - result the same.

Thank your for attention.

Answer 1

Update your Interceptor like this.

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

Answer 2

Thanks to mr. M. Deinum. The issue -
Don't use a welcome page and let all pages be served by the DispatcherServlet. additionaly can use:

 <mvc:view-controller path="/" view-name="first-view page"> 

Thanks all.
