在jsonpath中如何为嵌套的json对象放置新值？

Question

我有这样的杰森：

{
  "attachments": [
    "string"
  ],
  "contact": {
    "name": "Mahesh"
  },
  "contactCode": "C-0000001",
  "journalEntryCode": "JE-0000002",
  "linkedDocuments": [
    {
      "contactCode": "C-0000001",
      "documentCode": "0000018",
      "documentItemDetails": [
        {
          "productCode": "P-0000001"
        }
      ],
      "documentType": "QUOTATION",
    }
  ],
  "taxAmount": 2.322,
  "totalAmount": 12.322,
  "unitPriceGstInclusive": false
}

在“ linkedDocuments”下，我要为“ documentCode”放置/替换新值“ 1234”我尝试采用json路径进行跟踪：

JSONObject requestParams = Utilities.readJSON("createInvoiceFromQuote.json");

        requestParams.put("$.linkedDocuments[*].documentCode", "1234");

但是它只是像这样在json的末尾创建一个新字段“ $ .linkedDocuments [*]。documentCode”

{
  "attachments": [
    "string"
  ],
  "contact": {
    "name": "Mahesh"
  },
  "contactCode": "C-0000001",
  "journalEntryCode": "JE-0000002",
  "linkedDocuments": [
    {
      "contactCode": "C-0000001",
      "documentCode": "0000018",
      "documentItemDetails": [
        {
          "productCode": "P-0000001"
        }
      ],
      "documentType": "QUOTATION",
    }
  ],
  "taxAmount": 2.322,
  "totalAmount": 12.322,
  "unitPriceGstInclusive": false
  "$.linkedDocuments[*].documentCode":"1234"
}

应该是这样

{
  "attachments": [
    "string"
  ],
  "contact": {
    "name": "Mahesh"
  },
  "contactCode": "C-0000001",
  "journalEntryCode": "JE-0000002",
  "linkedDocuments": [
    {
      "contactCode": "C-0000001",
      "documentCode": "1234",
      "documentItemDetails": [
        {
          "productCode": "P-0000001"
        }
      ],
      "documentType": "QUOTATION",
    }
  ],
  "taxAmount": 2.322,
  "totalAmount": 12.322,
  "unitPriceGstInclusive": false
}

如何使用Java放置/替换嵌套字段值？

Answer 1

由于LinkedDocuments是JSONObject的JSONArray，因此“ $ .linkedDocuments [*]。documentCode”键将无法正常工作。要更新JSONArray中JSONObject的任何键，请访问JOSNArray并迭代所有JSONObject，然后执行更新。

Answer 2

您需要对代码进行小的更正。
