Spring的本地化不会切换语言

Spring的本地化不会切换语言

Vad*_*kry 8 java localization spring-mvc

主题是在主题中 - 我无法弄清楚我的Spring MVC应用程序中的语言环境切换有什么问题.作为一个教程,我正在使用该链接 +我尝试了在谷歌中发现的不同变体.当我点击我的网页链接更改语言时,字符串?lang=XX将被附加到地址,但没有任何反应.

这是我的servlet-context.xml

我messages_en.properties和messages_ru.properties我的src/main/resources目录.显然,我错过了一些细节,但我肯定无法解决问题.顺便说一句,当我改变<beans:property name="defaultLocale" value="en"/>语言中的值时,正确地改变了.我将衷心感谢您的帮助.

<mvc:annotaion-driven />LocaleChangeInterceptorXML配置中定义的覆盖.尝试将此(根据spring参考)添加到XML配置:

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

或者试图摆脱<mvc:annotaion-driven />,这里讨论.

这对我也有用.别人注意:我可能错了,但是mvc:interceptors在使用Spring MVC 3.1时似乎是必需的.另请注意,使用时请mvc:interceptors确保您没有handlermapping bean:

<bean id="handlerMapping"
    class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="interceptors">
        <ref bean="localeChangeInterceptor" />
    </property>
</bean>

有这个bean会导致错误:

"在设置bean属性'拦截器'时无法解析对bean'localeChangeInterceptor'的引用"这是我8小时挫折的根源.
