java - Spring LocaleResolver 对语言环境没有反应

Question

在我的应用程序中，我切换了两种语言 (Eng\Rus)，这两种语言必须更改应用程序的区域设置。但是，Spring LocaleResolver 没有对请求使用react。这是一个带有“locale”变量的自由标记下拉开关:

 <ul class="nav">
   <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown" ><@spring.message "header.lang_switch" /><b class="caret"></b></a>
        <ul class="dropdown-menu">
            <li><a href="?locale=en_US"><@spring.message "header.lang_switch_eng" /></a></li>
            <li><a href="?locale=ru_RU"><@spring.message "header.lang_switch_ru" /></a></li>
        </ul>
   </li>
</ul>

这是我的 spring-servlet.xml 配置:

<!-- serving up static resources -->
<mvc:resources mapping="/static/**" location="/static/"/>

<!-- Configures Handler Interceptors -->
<bean id="localeChangeInterceptor"
      class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"
      p:paramName="locale"/>

<!-- locale Resolver configuration-->
<bean id="localeResolver"
      class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
    <!--<property name="defaultLocale" value="en_US"/>-->
</bean>

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

<!-- Application Message Bundle -->
<bean id="messageSource"
      class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="defaultEncoding" value="UTF-8"/>
    <property name="fileEncodings" value="UTF-8"/>
    <property name="cacheSeconds" value="0"/>
    <property name="fallbackToSystemLocale" value="false"/>
    <property name="useCodeAsDefaultMessage" value="true"/>
    <property name="basenames">
        <list>
            <value>/WEB-INF/messages/messages</value>
            <value>/WEB-INF/messages/labels</value>
            <value>/WEB-INF/messages/include</value>
        </list>
    </property>
</bean>

和 web.xml 配置:

<filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<!-- ===================== i18n configurations =============================================== -->
<filter>
    <filter-name>localizationFilter</filter-name>
    <filter-class>org.springframework.web.filter.RequestContextFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>localizationFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

如果我在“localeResolver”中硬编码“defaultLocale”，页面将正确加载，并且所有翻译都将正确进行。我在 fireBug 中清楚地看到，切换语言环境后，页面标题中的语言环境发生了变化。但是，页面上的内容不会改变。

我拥有通常需要的所有配置:

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

LocalChangeInterseptor 中的更改没有带来任何更改:

<mvc:interceptors>
    <bean id="localeChangeInterceptor"
          class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"
          p:paramName="locale"/>
</mvc:interceptors>

还有一件事； Spring-security和Interceptor机制有什么关系吗？ 任何帮助表示赞赏!谢谢。

Answer 1

我的配置正在运行，我们之间最大的区别是我使用了“拦截器”标签:

<!-- Interceptors for theming support -->
<interceptors>
    <beans:bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" 
        p:paramName="lang"/>

</interceptors>

<!-- Beans for i18n support  -->
<beans:bean
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource"
    id="messageSource" p:basenames="WEB-INF/i18n/view,WEB-INF/i18n/presentation,WEB-INF/i18n/projects,WEB-INF/i18n/forms,WEB-INF/i18n/validation"
    p:fallbackToSystemLocale="false" />
<beans:bean class="org.springframework.web.servlet.i18n.CookieLocaleResolver"
    id="localeResolver" p:cookieName="locale" />

按照我的方式，它可以为你工作。它直接来自《Pro Spring 3》一书。

编辑:这是我的 web.xml，即使我从未对 i18n 支持进行更改
