Spring Roo 2.0.0.RC1：如果我在诊所示例中使用我的新语言Addon，我会得到很长的堆栈跟踪

测试新语言插件

我现在有德语的语言Addon，并在诊所的例子中使用ist。

安装新语言插件后我设置

web mvc language --code de --useAsDefault in clinic.roo

之前

web mvc language --code es

当我开始申请时，全部都是德语。但是在命令shell中，我启动了应用程序，会发生长堆栈跟踪。

只能从stacktrace中获取一小段代码。 然后我切换到西班牙语或英语没有堆栈跟踪。 当我切换回德语时，堆栈跟踪发生。 为什么？有什么问题？

我在northwind-multimodule中测试新语言并获取堆栈跟踪 当我切换到德语并且在menues不工作之后。我可以添加url param lang = en然后再次使用menues。

另一个备注：

标签用德语切换语言所有标签确定（我已将它们放在message_de.properties中）但是用西班牙语或英语标记德国标签是不行的。

在消息属性中没有适用于德语的language_Label属性，因为在I18N插件中，消息属性对于德语没有language_Label。 插件现在没有关于其他语言的任何内容。 我已手动添加此条目，然后一切正常。

好我测试它只使用普通的message.properties并将名称更改为message_de.properties。 然后构建新的插件，并在临床示例中使用语言并获取stacktrace：

当语言不是英语或西班牙语时，你似乎发现了Roo生成的Thymeleaf布局中的问题，以及moment.js库的webjar。

要解决此问题，您必须在 src / main / resources / templates / layouts 文件夹中编辑项目中生成的布局，并找到以下行：

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.13.0/locale/es.js" data-th-src="@{/webjars/momentjs//locale/}+ ${#locale.language}+'.js'" data-th-if="${#locale.language} != 'en' and ${#locale.language} != 'es'">
  </script>

似乎moment.js webjar包含所有语言环境相关文件的两个副本，webjars解析器找到它们并且不知道要使用哪个。要解决它，必须使用webjar版本的路径。此外，URL格式不正确。用以下代码替换上一个片段：

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.13.0/locale/es.js" data-th-src="@{/webjars/momentjs/2.13.0/locale}+ '/' + ${#locale.language}+'.js'" data-th-if="${#locale.language} != 'en' and ${#locale.language} != 'es'">
  </script>
