java如何取消设置/销毁一级JSONArray密钥

Question

我想知道如何取消设置或销毁一级JSON对象。 这可以使用任何JavaSpring框架来完成，也可以为这个解决方案定义任何自定义功能。 但需要在“txtFrameArr”的内部数组中保留数据，如下所示。例如，我有一个结果：

 [
  {
    "txtFrameArr": {
      "CEPDuplicateTextFrame1": [
        {
          "marked": 1,

I need to remove {"txtFrameArr"} but the key,value needs to be retain
Is there any specific function in Java Spring for this solution?

应该是通过删除“TXTFramerarr”来实现的

Answer 1

如果我正确理解你的意思，你可以使用JSON路径：

1. 获取对象的所有值
2. 使用提取的值创建新的json数组：

第一步，你可以使用com。乱穿马路。jsonpath:json path:*，用于第二步-GSON或Jackson

        <dependency>
            <groupId>com.jayway.jsonpath</groupId>
            <artifactId>json-path</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
            <version>2.8.6</version>
        </dependency>

代码如下所示：

        List<Map<String, Object>> frames = JsonPath.parse(json).read("$[*].txtFrameArr");
        String newJson = new Gson().toJson(frames);
        System.out.println("object: " + newJson);
