我在Websphere中使用Angular-EL表达式有什么问题？

我在Java Web应用程序中使用了完全服务器端的i18n机制 .

我们为 java.text.MessageFormat.format 函数创建了一个EL包装器，它将一个局部模式和参数作为输入 .

我需要显示随用户语言（服务器端）和Angular变量值而变化的文本 .

请考虑以下示例

• EN："Hello, {0}"

• IT："Ciao, {0}"

现在 {{vmApp.principal}} 是 'Bobby'

以下类型的表达式在Websphere中不起作用

${acme:messageFormat1(messages.GREETING,'{{vmApp.principal}}'}

错误是......

我的研究引导我到IBM的this article，但我没有使用保留的变量名 .

可能导致此问题的原因是什么？

我想呈现以下HTML

• EN："Hello, {}"

• IT："Ciao, {}"
