Mule DataWeave DB 结果到对象数组列表

Question

我正在尝试使用 Mule 3.7.3 中的 DataWeave 将 Db 结果集转换为 "Flight" 对象的 ArrayList。

我的代码如下图。我不是 DataWeave 专家:(

%dw 1.0
%type user=:object {class: "java.util.ArrayList<MyFlightClass>"}
%output application/java
---
payload map ((payload01 , indexOfPayload01) -> {
    airlineName: payload01.airlineName,
    departureDate: payload01.takeOffDate as :string,
    destination: payload01.toAirport,
    origination: payload01.fromAirport,
    price: payload01.price as :number
})

我得到的不是 MyFlightClass 的 ArrayList，而是 LinkedHashMap 的 ArrayList。我确定我遗漏了一些微不足道的东西:(。

Answer 1

将每个分配为飞行对象

%dw 1.0
%output application/java
---
payload map ((payload01 , indexOfPayload01) -> {
    airlineName: payload01.airlineName,
    departureDate: payload01.takeOffDate as :string,
    destination: payload01.toAirport,
    origination: payload01.fromAirport,
    price: payload01.price as :number
} as :object {class: "com.mulesoft.training.Flight"})
