Scala中通过JsonPath读取或者修改指定key的值_scala jsonpath 方法

pom.xml 中引入依赖

    <dependency>
      <groupId>com.jayway.jsonpath</groupId>
      <artifactId>json-path</artifactId>
      <version>2.4.0</version>
    </dependency>

  测试数据文件

{
  "visitPlanList": [
    {
      "visitBizId": "aaa",
      "subject": "Create Visit aaa",
      "startDateTime": "2021-08-13T07:00:00",
      "endDateTime": "2021-08-13T07:30:00",
      "visitTexts": [],
      "toBeReAssigned": false
    }
  ]
}

 
    val = 文件路径
//读文件
    val jsonString: String = Source.fromFile(value).mkString
//解析文件
    val context: DocumentContext = JsonPath.parse(jsonString)
    val resultDate: String = LocalDate.now().toString
//生成UUID
    val visitBid = UUID.randomUUI
