如何使spring mvc应用程序多语言？

我正在使用SpringMVC4开发web服务，我必须使它成为多语言的。这样：如果即将到来的url请求包含土耳其语的

“…？lang=tr”

，英语的

“…？lang=en”

。我在stackoverflow上读到

覆盖

LocaleChangeInterceptor

。但当我删除它时，应用程序不起作用了。我正在使用它。我还没有找到解决办法。对于下面的配置，即使我切换语言，消息也始终为英语。此外，我还需要用java而不是jsp获取lang消息。但当我初始化时，它总是在java类中返回默认消息。我把这里搞砸了。请求你的帮助

@Autowired
private MessageSource messageSource;

Locale locale = LocaleContextHolder.getLocale();
String msg = messageSource.getMessage("deneme", null, "Deault Message!", locale);

dispatcher servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

      <!-- Defining which view resolver to use -->
     <bean class= "org.springframework.web.servlet.view.InternalResourceViewResolver" > 
          <property name="prefix" value="/WEB-INF/views/" /> 
          <property name="suffix" value=".jsp" /> 
     </bean>
</beans>

将此项添加到xml中以注册localChangeInterceptor，它将正常工作

<mvc:annotation-driven/>
    <context:component-scan
        base-package="controller">
    </context:component-scan> 

    <bean id="handlerMapping"
            class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">

        </bean>

可能重复ofhttp://stackoverflow.com/questions/22490558/internationalization-with-spring-mvc?rq=1yes. 有点像我的问题。但我也在问如何用java获取消息。当我根据那篇文章修改xml时，我得到“没有名为”localeChangeInterceptor“的bean定义为”异常。还有这个错误：“类”org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping“被标记为已弃用”
