java - 使用java从路径创建JSON

Question

我需要从路径创建一个 JSON。例如，我的路径及其值如下所示

root/departments[name=dept1]/employees[id=emp1]/firstName = firstName
root/departments[name=dept1]/employees[id=emp1]/lastName = lastName
root/departments[name=dept1]/employees[id=emp2]/firstName = firstName
root/departments[name=dept2]/employees[id=emp1]/firstName = firstName

从这里我需要生成看起来像这样的json。

{
"root": {
    "departments": [
        {
            "name": "dept1",
            "employees": [
                {
                    "id": "emp1",
                    "firstName": "firstName",
                    "lastName": "lastName"
                },
                {
                    "id": "emp2",
                    "firstName": "firstName"
                }
            ]
        },
        {
            "name": "dept2",
            "employees": [
                {
                    "id": "emp1",
                    "firstName": "firstName"
                }
            ]
        }
    ]
}

}

当我签入 JsonPath 和 JsonPointers 时，不支持这种结构。
