spring 国际化

首先spring 配置

<bean id="messageSource"
    class="org.springframework.context.support.ResourceBundleMessageSource">
    <!-- 国际化信息所在的文件名,根据ResourceBundleMessageSource类加载资源文件.\src\main\resources\messages\messages_en_US.properties -->
    <property name="basename" value="message" />
    <!-- 如果在国际化资源文件中找不到对应代码的信息，就用这个代码作为名称 -->
    <property name="useCodeAsDefaultMessage" value="true" />
</bean>

<mvc:interceptors>
    <!-- <bean class="com.cetc.i18n.LanguageInterceptor" /> -->
    <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />
</mvc:interceptors>
    <!--cookie是为了避免setLocal错误，需要有一个实现-->
<bean id="localeResolver"
    class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
    <property name="cookieName">
        <value>locale</value>
    </property>
    <property name="cookieMaxAge">
        <!-- one year -->
        <value>31536000</value>
    </property>
</bean>

国际化切换

@RequestMapping("test")
@ResponseBody
public String test(HttpServletRequest request, HttpServletResponse response,
        @RequestParam(value = "langType", defaultValue = "zh") String langType) {

    Locale locale = new Locale("zh", "CN");
    if (langType.equals("zh")) {
        (new CookieLocaleResolver()).setLocale(request, response, locale);
    } else if (langType.equals("en")) {
        locale = new Locale("en", "US");
        (new CookieLocaleResolver()).setLocale(request, response, locale);
    } else
        (new CookieLocaleResolver()).setLocale(request, response, LocaleContextHolder.getLocale());
    // 从后台代码获取国际化信息
    // RequestContext requestContext = new RequestContext(request);
    // String msg = requestContext.getMessage("msg");
    return "返回数据";
}

@RequestMapping("local")
@ResponseBody
public String local(HttpServletRequest request, HttpServletResponse response,
        @RequestParam(value = "langType", defaultValue = "zh") String langType) {
    LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(request);
    System.out.println("入口--->" + langType);
    Locale locale = new Locale("zh", "CN");
    if (langType.equals("zh")) {
        localeResolver.setLocale(request, response, locale);
    } else if (langType.equals("en")) {
        locale = new Locale("en", "US");
        localeResolver.setLocale(request, response, locale);
    } else {
        localeResolver.setLocale(request, response, LocaleContextHolder.getLocale());
    }

    System.out.println("出口--->" + locale.getLanguage());
    return "本地国际化";
}

切换的另一种方式（没什么用，网上的）

public class LanguageInterceptor extends LocaleChangeInterceptor {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
    Locale newLocale = getLocale(request.getParameter("lang"));
    LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(request);

    if (localeResolver == null) {
        throw new IllegalStateException("No LocaleResolver found: not in a DispatcherServlet request?");
    }

    localeResolver.setLocale(request, response, newLocale);

    return true;
}

 // 根据language 获取Locale
public static Locale getLocale(String language) {
    System.out.println("进入-->" + language);
//      Locale locale = new Locale("zh", "CN");
    Locale locale = new Locale("en", "US");
//      if (language != null && language.equals("en")) {
//          locale = new Locale("en", "US");
//      }
    System.out.println("出口-->" + locale.getLanguage());
return locale;
}

}

JSP部分，使用spring 标签，所有的请求需要经过后台.do 不然无法解析

<!--引入spring标签-->
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
 <!--标签使用-->
alert('<spring:message code="mTest"/>');

配置文件，注意名称，需要放到resource目录下
