设置特定的 JSONPATH 元素值

Set specific JSONPATH element value

我试图从以下 JSON 文本中设置作者值,但我的代码正在删除 json 文本的所有其他子项。

   {
    "store": {
        "book": [
            {
                "category": "reference",
                "author": "XXXXXXXXXXXXXXXXX",
                "title": "Sayings of the Century",
                "price": 8.95
            },
            {
                "category": "fiction",
                "author": "Evelyn Waugh",
                "title": "Sword of Honour",
                "price": XXXXXXXXXXXXXXXXXXXXX
            },
            {
                "category": "fiction",
                "author": "Herman Melville",
                "title": "Moby Dick",
                "isbn": "0-553-21311-3",
                "price": 8.99
            },
            {
                "category": "fiction",
                "author": "J. R. R. Tolkien",
                "title": "The Lord of the Rings",
                "isbn": "0-395-19395-8",
                "price": 22.99
            }
        ],
        "bicycle": {
            "color": "red",
            "price": 19.95
        }
    },
    "expensive": 10
}

我尝试将第一本书中的作者更新为其他值,如下所示。

Object updatedJson = JsonPath.using(configuration).parse(jsonInput).json();
String jayPath = "$..book[0].author";
String tagValue = "ReplacedText";
                String jsonToParse = updatedJson.toString();
                updatedJson = JsonPath.parse(jsonToParse).set(jayPath, tagValue).json();

设置步骤后,我的 json 只有 book[1] 的内容,如下所示。请告知我怎样才能得到我给出的整个 json 输入和替换值作为输出。

{store={book=[{"category"=reference, author=XXXXXXXXXXXXXXXXX, title=Sayings of the Century, price=8.95}

此致, 萨提斯

无需将 DocumentContext 转换为 json

即可正常工作
public static void main(String[] args) {
    DocumentContext json = JsonPath.using(configuration).parse(jsonInput);
    String jayPath = "$..book[0].author";
    String tagValue = "ReplacedText";
    System.out.println(json.set(jayPath, tagValue).jsonString());
}
