我的 mule 代码正在打两个表并获取一些详细信息。第一个是订单详细信息，我将其存储在流变量中，即订单，另一个数据库正在返回我存储在orderitem变量中的订单项目详细信息。
我想根据一个条件聚合两个有效负载。每个 orderId 都有订单项（存储在 flowVars.orderitem 中）并将这些订单项映射到各自的 orderID。
flowVars.order 值如下
[{partnerId=e83185e9f33e4234ba9eaa81dba515ad, orderId=12345, orderDate=2017-02-28 16:41:41.0, id=22}, {partnerId=e83185e9f33e4234ba9eaa81dba515ad, orderId=123456, orderDate=2017-02-28 16:41:41.0, id=23}, {partnerId=e83185e9f33e4234ba9eaa81dba515ad, orderId=11111, orderDate=2017-02-28 16:41:41.0, id=24}, {partnerId=e83185e9f33e4234ba9eaa81dba515ad, orderId=321123, orderDate=2017-05-19 15:25:41.0, id=26}]
和flowVars.orderitem 值如下
[{productCode=ELT-LP-ICND1-020067, orderId=12345, quantity=10, id=14}, {productCode=ELT-IP-ICND1-1.0, orderId=12345, quantity=11, id=15}, {productCode=ELT-LP-ICND1-020067, orderId=123456, quantity=12, id=16}, {productCode=ELT-IP-ICND1-1.0, orderId=123456, quantity=13, id=17}, {productCode=ELT-LP-ICND1-020067, orderId=11111, quantity=14, id=18}, {productCode=ELT-IP-ICND1-1.0, orderId=11111, quantity=15, id=19}, {productCode=ELT-LP-ICND2-020067, orderId=321123, quantity=5, id=20}]
预期产出
[
{
"orderId": "12345",

在这里，我需要显示订单的各个订单项目详细信息。所以基本上我需要结合两个有效载荷。
我尝试使用 dataweave 但没有运气。
数据编织代码：
%dw 1.0
%output application/json
%var mergeddata = flowVars.orderitem groupBy $.orderId
---
flowVars.order map ((data,index) ->
{
orderid: data.orderId,
partnerid: data.partnerId,
orderdate: data.orderDate,
order: flowVars.orderitem default [] map ((data1 ,indexOf) ->
{
(productcode: data1.productCode) when (data1.orderId == data.orderId),
(quantity: data1.quantity) when (data1.orderId == data.orderId) ,
(id: data1.id) when (data1.orderId == data.orderId)
}
)})
以及转换后的输出：
{
"orderid": "12345",
"partnerid": "e83185e9f33e4234ba9eaa81dba515ad",
"orderdate": "2017-02-28T16:41:41",
"order": [
{
"productcode": "ELT-LP-ICND1-020067",
"quantity": 10,
"id": 14
},
{
"productcode": "ELT-IP-ICND1-1.0",
"quantity": 11,
"id": 15
},
{
},
{
},
{
},
{
},
{
}
]
},
{

{
"productcode": "ELT-IP-ICND1-1.0",
"quantity": 15,
"id": 19
},
{
}
]
},
{
"orderid": "321123",
"partnerid": "e83185e9f33e4234ba9eaa81dba515ad",
"orderdate": "2017-05-19T15:25:41",
"order": [

{
"productcode": "ELT-LP-ICND2-020067",
"quantity": 5,
"id": 20
}
]
}
]
如您所见，我几乎就在那里，并且能够将订单项目详细信息与相应的 orderId 映射，但在转换后我仍然得到一些空白值。
任何人都可以帮助我实现预期的输出。提前致谢！！！
