解析国际化中的异常 - 未找到消息

标签： jsf internationalization el

我在开始开发之前试图将我的应用程序国际化，以便我以后更容易扩展它。

然而，尽管我尝试按照教程进行操作，但我总是得到同样的错误：我的xhtml中的标签无法解析，就好像按摩甚至不存在一样（即使Eclipse自动完成它们）。

stacktrace的摘要如下（Here for the full stacktrace at Pastebin）：

Type Exception Report

我正在使用Java 8 + JSF2.2 + Tomcat 9

答案 0 :(得分：0)

我非常有信心将#{msg.['title.index']}"更改为#{msg['title.index']}"（删除。）会有很大帮助
