下面是我的Spring上下文文件，但是当尝试更改本地lang时，它没有切换....我在google上做了很多搜索+在stackoverflow上引用其他问题，但没有什么是有用的..大多数地方建议在bean标记localeChangeInterceptor周围添加<mvc:interceptors>标记。

您正在使用<mvc:annotation-driven />，那么您还必须使用命名空间来注册拦截器。使用<mvc:interceptors />注册您的拦截器，而不是声明（另一个未使用的）DefaultAnnotationHandlerMapping。
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
</bean>
</mvc:interceptors>
由于使用了<context:annotation-config />，我们暗示了另一件事<context:component-scan />。

很抱歉，我没有足够的评分来评论，但正如M.Denim指出的那样，很可能你的index.jsp在WEB-INF文件夹之外。 您可以将index.jsp移动到WEB-INF / jsp /文件夹中，并在配置中添加静态视图以进行渲染，而无需使用显式控制器：
<mvc:view-controller path="/" view-name="index"/>
整个事情将是：
