如何在jsonpath中获取条件

{
  "employees": [
    {
      "name": "John",
      "age": 30,
      "department": "IT"
    },
    {
      "name": "Jane",
      "age": 25,
      "department": "HR"
    },
    {
      "name": "Bob",
      "age": 35,
      "department": "Finance"
    }
  ]
}

$.employees[?(@.age > 30)]

[
  {
    "name": "Bob",
    "age": 35,
    "department": "Finance"
  }
]
