我在SpringMVC中面临语言区域设置更改的问题。当我打开fr等新语言时，浏览器会显示参数名称。但是，它并没有改变语言。我还用$ {pageContext.response.locale}测试。它没有改变。在我的代码下面。

答案 0 :(得分：1)
那是因为你还没有注册你的拦截器。
<bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<ref bean="localeChangeInterceptor" />
</property>
</bean>
由于您使用<mvc:annotation-driven />，因此该bean定义无法执行任何操作。
您应该使用<mvc:interceptors />标记正确注册拦截器。
<mvc:interceptors>
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
</bean>
</mvc:interceptors>
这将使用HandlerMapping标记配置的所有已配置<mvc:annotation-driven />实例注册您的拦截器。另请参阅参考指南中的Configuring Interceptors。
