在Spring MVC中更改过滤器类中的语言环境

Question

如何在springMVC中更改过滤器类中的语言环境.

在我的过滤器类中我使用下面的代码:

LocaleContextHolder.setLocale(new Locale(lang));

我传递的郎值是"ms".

当我从UI更改语言环境时,它工作正常.我想要改变过滤器calss,它不起作用.

在我配置的东西下面的spring-servlet.xml中.

<bean id="localeResolver"
    class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
    <property name="defaultLocale" value="en" />    
</bean>
<mvc:interceptors>
    <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName">
            <value>locale</value>
        </property>
    </bean>
</mvc:interceptors>

Web.xml org.springframework.web.context.ContextLoaderListener

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
    classpath:/conf/context/spring-platform.xml 
    classpath:/conf/context/spring-beans.xml 
    classpath:/conf/context/spring-security.xml 
    </param-value>
</context-param>


<filter>
    <filter-name>accessFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>

<servlet-mapping>

</servlet-mapping>

<servlet-mapping>

    <url-pattern>/services/*</url-pattern>

注意到正在发生(Locale没有改变).日志或控制台中没有异常.

您正在使用SessionLocaleResolver,请尝试使用以下代码.

Locale locale = new Locale(lang);
WebUtils.setSessionAttribute(httpRequest,SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale);

它会将您的语言环境设置为会话.我认为它会解决你的问题.
