Java 如何过滤JSON数组

我有一个动态JSON数组，需要根据“isCalculatedField”：false过滤JSON

如何获取包含“isCalculatedField”的子JSON列表：false？？ 我有字符串形式的JSON数据。

使用：

你可以使用图书馆。通过使用它，您可以在读取JSON数据时过滤JSON

您将定义一个包含映射定义的YAML文件

映射文件：

result:
  type: array     # result is array
  path: /
  filter: self.data.isCalculatedField  # filter by isCalculatedField
  fields:
    id:
    description:
    modelPath:
    isCalculatedField: boolean
    format:

使用DSM过滤数据

DSM dsm=new DSMBuilder(new File("path/to/config.yaml")).create();
Object object=dsm.toObject(new File("path/to/data.json");

结果如下：

[ {
  "id" : "CX.YEARS.AT.EMPLOYER",
  "description" : "Years employed",
  "format" : "DROPDOWNLIST",
  "modelPath" : "Loan.CustomFields[(FieldName == 'CX.YEARS.AT.EMPLOYER')].StringValue",
  "isCalculatedField" : true
}, {
  "id" : "CX.YEARS.AT.RESIDENCE",
  "description" : "Years at residence",
  "format" : "DROPDOWNLIST",
  "modelPath" : "Loan.CustomFields[(FieldName == 'CX.YEARS.AT.RESIDENCE')].StringValue",
  "isCalculatedField" : true
}, {
  "id" : "CX.YEARS.AT.RESIDENCE",
  "description" : "Years at residence",
  "format" : "DROPDOWNLIST",
  "modelPath" : "Loan.CustomFields[(FieldName == 'CX.YEARS.AT.RESIDENCE')].StringValue",
  "isCalculatedField" : true
} ]

请包括保存此数据的声明/实际数据结构。这完全取决于数据类型，问题中显示的内容可以是任何内容：字符串、集合、列表……欢迎使用堆栈溢出！在这里提问时，请向我们展示您自己试图解决的问题。同时，这里有一个建议：解析JSON。如果您使用的是Visual Studio，您可以使用Newtonsoft的JSON解析器来实现此目的。简单的解决方案是，迭代JSON数组（使用任何JSON API），检查

isCalculatedField

的值，并相应地创建一个新的JSON。试着带着更多的信息回来。仅供参考：请参见和您的问题。

result:
  type: array     # result is array
  path: /
  filter: self.data.isCalculatedField  # filter by isCalculatedField
  fields:
    id:
    description:
    modelPath:
    isCalculatedField: boolean
    format:

DSM dsm=new DSMBuilder(new File("path/to/config.yaml")).create();
Object object=dsm.toObject(new File("path/to/data.json");

  "id" : "CX.YEARS.AT.EMPLOYER",
  "description" : "Years employed",
  "format" : "DROPDOWNLIST",
  "modelPath" : "Loan.CustomFields[(FieldName == 'CX.YEARS.AT.EMPLOYER')].StringValue",
  "isCalculatedField" : true
