Question

我正在一个需要动态更改语言的网站上工作我使用的是弹簧4.2.4.RELEASE.jar

我已经制作了proerties文件。属性文件目录是WebContent \ language_src \ content_en_US.properties为英语印地文的content_hi_IN.properties

和eclipse在拦截器标签上显示错误

cvc-complex-type.2.4.a: Invalid content was found starting with element 'interceptors'. One of '{"springframework.org/schema/beans":import, "springframework.org schema/beans":alias, "springframework.org/schema/beans":bean, WC[##other:"springframework.org/schema/beans"], "springframework.org/schema beans":beans}'

DefaultServlet-servlet.xml代码：

    <mvc:resources mapping="/resources/**" location="/resources/design/" />
    <mvc:resources mapping="/language_src/**" location="/language_src/" />

当我运行我的代码时，它会给出异常

Answer 1

我怀疑这是你的例外问题，但是，这是怎么回事。将您的消息来源更改为：

@Bean
public MessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("/WEB-INF/propFiles/messages");
    messageSource.setDefaultEncoding("UTF-8");
    return messageSource;
}

请注意，您的属性文件应该以：messages_en，messages_in等开头。

定义LocalChangeInterceptor bean：

@Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
    LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
    localeChangeInterceptor.setParamName("lang");
    return localeChangeInterceptor;
}

它让你有能力改变语言。即 www.mysite.com?lang=en改为英语。

另外，LocaleResolver bean：

@Bean
public LocaleResolver localeResolver() {
    SessionLocaleResolver localeResolver = new SessionLocaleResolver();
    localeResolver.setDefaultLocale(new Locale("en"));
    return localeResolver;
}

设置默认语言。在这种情况下，英语。

Answer 2

您必须为拦截器节点提供mvc名称空间。

<mvc:interceptors>...</mvc:interceptors>

Parser理所当然地抱怨，因为在bean命名空间中没有找到拦截器标记（这是你的默认值）
