如何在Java中构造JSON数据 [英] How to construct JSON data in Java

问题描述

我想使用Apache HttpClient来发布JSON请求.但是，我想将Json数据发送到目标系统的过程并不复杂.以下是我要发送的json

I would want to POST JSON request using Apache HttpClient. But the Json data is little complex that I would want to send to target system. Below is the json that I would send

{
  "name":"xyz",
  "id":"428",
"mailId":
  [
   "[e-mail]"
  ],
  "bundle1":
  {
      "opwarden":
      {
         "number":"132344345",
         "title":"title"
      }     
  }
}

在Java中，对json数据进行收缩的最佳和最简便的方法是什么?

What is the best and easiest way to contract above json data in Java?

推荐答案

使用POJO和和Opwarden:

public class Opwarden {

    private final String number;
    private final String title;

    public Opwarden(final String number, final String title) {
        this.number = number;
        this.title = title;
    }

    public String getNumber() {
        return number;
    }

    public String getTitle() {
        return title;
    }
}

您可以使用以下方法创建JSON:

You can create a JSON with:

ObjectMapper objectMapper = new ObjectMapper();
Data data = new Data("xyz", "428", List.of("[e-mail]"), List.of(new Opwarden("132344345", "title")));
System.out.println(objectMapper.writeValueAsString(data));

输出:

{
    "name": "xyz",
    "id": "428",
    "mailId": [
        "[e-mail]"
    ],
    "bundle1": [
        {
            "number": "132344345",
            "title": "title"
        }
    ]
}
