在 Talend 中合并多个 JSON 条目

Question

我正在尝试使用 tExtractJSONFields。在 JSON 文本中有多个作者，其 FirstName 和 LastName 在不同的标签下。我想将两者结合起来并分隔每个作者的名字，然后可以在 tLogRow 中看到。

我在tExtractJSONFields组件的"columns"部分勾选了Array的字段：

我从 tLogRow 获取输出为 [Han, Kamber], [Jiawei, Micheline]:

我要输出韩家伟；坎贝尔，米歇尔。

Answer 1

我可以使用 tJavaRow。将输入分开，因为它们是数组，然后合并相关索引。它非常复杂，但我不需要它。我正在寻找的信息已经存在于源中，我只需要重新路由即可。
