为什么我将fmt:message用于JSP页面时会出现这种国际化\本地化问题?

我遇到了与旧Java Web应用程序的internazionalization \ localization相关的以下问题。

所以我有这种情况:我有两个非常相似的Web应用程序,我不得不从第一个获取JSP页面并将其复制到第二个。

此JSP页面包含以下内容:

<thead>
    <tr>
        <th><input id="myCheck" onclick="changeBoxAll(this)" type="checkbox"></th>
        <th></th>
        <th><fmt:message key="emittente_fatt"/></th>
        <th><fmt:message key="mandataria"/></th>
        <th><fmt:message key="id"/></th>
        <th><fmt:message key="numero_fatt"/></th>
        <th><fmt:message key="data_invio"/></th>
        <th><fmt:message key="data_approvazione"/></th>
        <th><fmt:message key="data_documento"/></th>
        <th><fmt:message key="totale_fattura"/></th>
        <th><fmt:message key="stato"/></th>
    </tr>
</thead>

正如您在上面的代码中看到的,它包含 标记。

此标记属于JSTL标记库,用于将键映射到本地化消息并执行参数替换。

因此,例如,第一个应用程序中的 显示为发票发行者(如果用户是engligh)或 emittente_fatt = Emittente fattura (如果用户是意大利人)。

在第一个应用程序(从我将JSP推入第二个应用程序的orignal)中,它工作正常,这些日期存储在2个属性文件中,这些文件各自名称:

  • /src/config/l18n/messages_en.properties
  • /src/config/l18n/messages_it.properties

(第一个用于英文版,第二个用于意大利版)。

因此,在第二个Web应用程序中,我没有 l18n 子文件夹进入 / src / config / 文件夹,因此,当我执行上一个JSP页面时,我看到了密钥消息属性文件(例如: ??? emittente_fatt ??? 而不是值发票发行者

好的,所以我尝试复制并粘贴 l18n 文件夹(及其所有内容)并将其放入第二个Web应用程序的 / src / config /

现在,如果我从Intellij工作到我的视图,我可以看到捆绑的 messages_en.properties messages_it.properties 的链接(CTRL +点击关键字标记如果打开其中一个文件我可以选择。

因此,这些属性文件似乎已正确捆绑到项目中。

问题是,如果我尝试运行我的项目,我仍然会看到密钥,而不是相关的值,我看到这样的事情:

为什么呢?我错过了什么?我怎样才能解决这个问题并正确地将价值看到我的?

答案 0 :(得分:1)

您的JSP需要两个taglib:

<%@ taglib uri="/WEB-INF/displaytag-11.tld" prefix="display" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

您的web.xml未加载第二个taglib - 必须如下所示并包含两个taglib条目

<taglib> 
    <taglib-uri>http://displaytag.sf.net</taglib-uri> 
    <taglib-location>/WEB-INF/displaytag-11.tld</taglib-location>
</taglib>
<taglib>
  <taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
  <taglib-location>/WEB-INF/lib/fmt.tld</taglib-location>
</taglib>

并提供包含WEB-INF/lib

的文件夹fmt.tld
