为帖子请求创建一个json [英] Creating a json for a post request

问题描述

我正在尝试将JSON字符串发送到post方法以便接收航班信息，我有以下json示例我必须修改以提出不同的请求

I am trying to send JSON string to post method in order to receive flights information, i have the following json example i must modify to make different requests

{
  "request": {
    "passengers": {
      "adultCount": 1
    },
    "slice": [
      {
        "origin": "BOS",
        "destination": "LAX",
        "date": "YYYY-MM-DD"
      },
      {
        "origin": "LAX",
        "destination": "BOS",
        "date": "YYYY-MM-DD"
      }
    ]
  }
}

我有以下课程

public class Request {
    public class Passengers{
        private int adultCount;

        public int getAdultCount() {
            return adultCount;
        }

        public void setAdultCount(int adultCount) {
            this.adultCount = adultCount;
        }
    }

    private List<Slice> slice;

    public List<Slice> getSlice() {
        return slice;
    }

    public void setSlice(List<Slice> slice) {
        this.slice = slice;
    }


    public static class Slice{
        private String origin;
        private String destination;
        private String date;

        public String getOrigin() {
            return origin;
        }

        public void setOrigin(String origin) {
            this.origin = origin;
        }

        public String getDestination() {
            return destination;
        }

        public void setDestination(String destination) {
            this.destination = destination;
        }

        public String getDate() {
            return date;
        }

        public void setDate(String date) {
            this.date = date;
        }
    }
}

我如何映射此类设置值并使用相同的格式创建不同的json？我正在尝试杰克逊，但我没有得到合适的输出

how do i map this class to set the values and create a different json with the same format? i am trying with Jackson but im getting no suitable output

推荐答案

这是JSON格式。了解它。

JSON字符串映射到Java String 。 JSON编号映射到Java Number 类型。 JSON数组映射到集合类型或数组类型。 JSON对象映射到Java Map 类型或任何其他Java类型（之前未提及）。

A JSON string maps to a Java String. A JSON number maps to a Java Number type. A JSON array maps to a Collection type or an array type. A JSON object maps to a Java Map type or any other Java type (not mentioned previously).

所以Java类如

class Foo {
    String name;
    int[] array;
    Map<String, List<Double>> ref;
}

映射到

{
    "name" : "string",
    "array" : [1, 2, 3],
    "ref" : {
        "val1" : [1.2, 3.4]
    }
}

您的JSON是根目录下的JSON对象。它包含

Your JSON is a JSON object at the root. It contains

"request": {

这是一个键值对，其中键是JSON字符串，值是JSON对象。

which is a key value pair where the key is a JSON string and the value is a JSON object.

这应该告诉你您需要一个带有名为 request 的字段的Java对象，该字段应该引用另一个对象。递归地执行此分析，您将获得Java对象格式。

This should tell you that you need a Java object with a field named request which should be referencing another object. Do this analysis recursively and you will get your Java Object formats.
