Question

我想将动态分隔符传递给csv编组，如下所示。

<marshal>
    <csv delimiter="${header.FIELD_DELIMITER}"/>
</marshal>

当我尝试如上所述时，我得到了这个例外：

Answer 1

而不是这样做

<marshal>
    <csv delimiter="${header.FIELD_DELIMITER}"/>
</marshal>

你需要这样做：

<toD uri="dataformat:csv:marshal?delimiter=${header.FIELD_DELIMITER}"/>

这是动态路由，只要您想根据运行时值在运行时创建URI，就需要使用它。

你不能用元帅那样做。但是，您可以使用dataformat端点和动态模式。有关详细信息，请访问：
