如果您使用的是spring security
，请将您的LocaleChangeInterceptor放入mvc中：拦截器标记如

In case you are using spring security put your LocaleChangeInterceptor inside mvc:interceptors tag like

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

并从配置中删除handlerMapping bean。希望它能正常工作。
