编写带条件判断的Jolt规格：根据restrictionType设置布尔属性

需求说明 #

当输入JSON中body.Contract.stayRestrictions[]内的restrictionType值为"ClosedToArrival"时，在输出JSON的body.Block.stayRestriction[]中设置isClosedToArrival="true"；否则设置为"false"。

[
  {
    "operation": "shift",
    "spec": {
      "body": {
        "Contract": {
          "stayRestrictions": {
            "*": {
              "restrictionType": {
                "ClosedToArrival": {
                  "#true": "body.Block.stayRestriction[&3].isClosedToArrival"
                },
                "*": {
                  "#false": "body.Block.stayRestriction[&3].isClosedToArrival"
                }
              }
            }
          }
        }
      }
    }
  }
]

输入输出验证 #

输入示例

{
  "body": {
    "Contract": {
      "stayRestrictions": [
        {
          "restrictionType": "ClosedToArrival"
        }
      ]
    }
  }
}

输出示例

{
  "body": {
    "Block": {
      "stayRestriction": [
        {
          "isClosedToArrival": "true"
        }
      ]
    }
  }
}

规格说明 #

• 采用shift操作完成字段映射与条件分支判断
• 通过*遍历stayRestrictions数组的每一项元素
• 针对restrictionType的值做精准匹配：匹配到ClosedToArrival时赋值"true"，其余情况统一赋值"false"
• &3用于回溯到数组的索引层级，确保输出数组结构与输入数组的元素位置一一对应
