如何將SFTP字節有效載荷轉換爲數據編織中的java

Question

我想使用數據織物將SFTP字節有效載荷轉換爲java，以便我可以使用現有流程循環輸入記錄。我該怎麼做呢？

我已經在Dataweave中將它設置爲java，並且預覽應該輸出正確的輸出，但是當我運行它時它是一個字節，並且我轉換爲例如Transform消息連接器之前的字符串在轉換消息連接器之後保持爲字符串。

Answer 1

嘗試登錄消息#[message.payloadAs(java.lang.String)]而不是#[payload]。

這<dw:set-payload>

希望這有助於之前還添加<dw:input-payload mimeType="application/csv" />線。
