Mule 比较2个JSON数组以获得匹配和不匹配的输出

我需要使用Mule 4 dataweave 2.0比较2个JSON数组，以获得匹配和不匹配的输出。 下面给出了示例输入JSON负载：

[
    {
        "CODE": "A11",
        "NAME": "Alpha",
        "ID": "C10000"
    },
    {
        "CODE": "B12",
        "NAME": "Bravo",
        "ID": "B20000"
    },
    {
        "CODE": "C11",
        "NAME": "Charlie",
        "ID": "C30000"
    },
    {
        "CODE": "D12",
        "NAME": "Delta",
        "ID": "D40000"
    },
    {
        "CODE": "E12",
        "NAME": "Echo",
        "ID": "E50000"
    }
]

这必须与下面的ID/IDENTITY字段进行比较

[
    {
        "IDENTITY": "D40000",
        "NM": "Delta"
    },
    {
        "IDENTITY": "C30000",
        "NM": "Charlie"
    }
]

我的预期输出是包含匹配和不匹配对象的2个变量数组：

varMatch: 
[
    {
        "CODE": "C11",
        "NAME": "Charlie",
        "ID": "C30000"
    },
    {
        "CODE": "D12",
        "NAME": "Delta",
        "ID": "D40000"
    }
]
varUnmatch:
[
    {
        "CODE": "A11",
        "NAME": "Alpha",
        "ID": "C10000"
    },
    {
        "CODE": "B12",
        "NAME": "Bravo",
        "ID": "B20000"
    },
    {
        "CODE": "E12",
        "NAME": "Echo",
        "ID": "E50000"
    }
]

---

如果ID映射来自其他地方，并且您无法更改其结构，我可能会重新映射它，然后像这样使用它：

%dw 2.0
output application/json

var identMap = [
    {
        "IDENTITY": "D40000",
        "NM": "Delta"
    },
    {
        "IDENTITY": "C30000",
        "NM": "Charlie"
    }
]

var remapped = identMap reduce ((item,accum={}) -> accum ++ (item.IDENTITY): 1)

---
payload groupBy (if (remapped[$.ID]?) "varMatched" else "varUnmatched")

产生

{
  "varUnmatched": [
    {
      "CODE": "A11",
      "NAME": "Alpha",
      "ID": "C10000"
    },
    {
      "CODE": "B12",
      "NAME": "Bravo",
      "ID": "B20000"
    },
    {
      "CODE": "E12",
      "NAME": "Echo",
      "ID": "E50000"
    }
  ],
  "varMatched": [
    {
      "CODE": "C11",
      "NAME": "Charlie",
      "ID": "C30000"
    },
    {
      "CODE": "D12",
      "NAME": "Delta",
      "ID": "D40000"
    }
  ]
}

%dw 2.0

var identMap = [
    {
        "IDENTITY": "D40000",
        "NM": "Delta"
    },
    {
        "IDENTITY": "C30000",
        "NM": "Charlie"
    }
]

var remapped = identMap reduce ((item,accum={}) -> accum ++ (item.IDENTITY): 1)

---
payload groupBy (if (remapped[$.ID]?) "varMatched" else "varUnmatched")

产生

{
  "varUnmatched": [
    {
      "CODE": "A11",
      "NAME": "Alpha",
      "ID": "C10000"
    },
    {
      "CODE": "B12",
      "NAME": "Bravo",
      "ID": "B20000"
    },
    {
      "CODE": "E12",
      "NAME": "Echo",
      "ID": "E50000"
    }
  ],
  "varMatched": [
    {
      "CODE": "C11",
      "NAME": "Charlie",
      "ID": "C30000"
    },
    {
      "CODE": "D12",
      "NAME": "Delta",
      "ID": "D40000"
    }
  ]
}

希望这有帮助

谢谢你的回答。我会试试这个。谢谢你的回答。我会尝试一下。谢谢你的回答。谢谢你的回答。谢谢你提供了一个替代的解决方案，非常感谢。只是为了语义准确<代码>（data dw:：core:：Array:：partition（e）->searchData.*标识包含e.ID）mapObject{（（$$）用（“varMatch”）替换“success”）用“varUnMatched”替换“failure”）：$}非常感谢您提供了另一种解决方案，非常感谢。只是为了在语义上准确<代码>（数据dw:：core:：array:：partition（e）->searchData.*标识包含e.ID）映射对象{（（$$）将“success”替换为（“varMatch”））将“failure”替换为“varUnMatched”）：$}
