Spring MVC 3 Locale使用链接无法更改

Question

编辑:我的Spring框架版本3.0.5

这是一个小问题,当我点击语言转换器链接时,语言没有改变.

语言文件(messages_xx.properties)位于类路径i18n目录中.文件是:

i18n/messages_en.properties
i18n/messages_ar.properties

<!-- Component scanner. This is used to automatically find Spring annotations like @Service and @Repository -->
    <context:component-scan base-package="com.keype" />

    <!-- Annotation driven programming model -->
    <mvc:annotation-driven />   
    <context:annotation-config />
    <mvc:resources mapping="/static/**" location="/static/" />


    <!-- Session Object Configuration -->
    <bean id="session" class="com.keype.system.Session" scope="session">
        <aop:scoped-proxy />
    </bean>

    <!-- The View Resolver -->
    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/jsp/"
          p:suffix=".jsp"
          />

    <!-- i18n Configuration. Default language is english. Change language using ?language=en -->
    <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName" value="lang" />
    </bean>

    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
        <property name="defaultLocale" value="en" />
    </bean>

    <!-- Message text files. This is set UTF-8 to display Arabic UTF correctly. -->    
    <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
        <property name="basename" value="classpath:i18n/messages" />
        <property name="defaultEncoding" value="UTF-8"/>
    </bean>

JSP代码中的一节

<a href="?lang=ar"><spring:message code="header.arabic" /></a> | 
    <a href="?lang=en"><spring:message code="header.english" /></a> 

问题是,当我单击上面的链接来更改语言时,语言环境更改功能无效.我通过将"defaultLocate"更改为"ar"进行测试,并且我收到了阿拉伯语文本.

这可能有什么问题？tomcat日志中也没有任何内容.

您必须在Spring-MVC的MVC拦截器中注册localeChangeInterceptor才能考虑它.将拦截器添加到配置中:

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