How to convert List<JsonObject> to JsonArray in JAVA

问题

我已经编写了一段代码,需要从一个“select * 查询”中创建一个JSON格式的输出。到目前为止,我能够获取以下输出,但我需要将其包装在“users”内:

{
  "displayName": "Tony Stark",
  "givenName": "Tony",
  "surname": "Stark"
},
{
  "displayName": "James Martin",
  "givenName": "James",
  "surname": "Martin"
}

我需要像这样的格式:

{
   "users": 
      [
            {
                  "displayName": "Tony Stark",
                  "givenName": "Toney",
                  "surname": "Stark"
            },
            {
                  "displayName": "James Martin",
                  "givenName": "James",
                  "surname": "Martin"
            }
      ]
}

请帮助我解决这个问题。

英文:

I have written a code, where I need to create a JSON format output from a "select * query". So far I am able to get the output like this, but I have to wrap it up inside "users"

{
  &quot;displayName&quot;: &quot;Tony Stark&quot;,
  &quot;givenName&quot;: &quot;Tony&quot;,
  &quot;surname&quot;: &quot;Stark&quot;
},
{
  &quot;displayName&quot;: &quot;James Martin&quot;,
  &quot;givenName&quot;: &quot;James&quot;,
  &quot;surname&quot;: &quot;Martin&quot;
}

I need something like this:

{
   &quot;users&quot;: 
      [
            {
                  &quot;displayName&quot;: &quot;Tony Stark&quot;,
                  &quot;givenName&quot;: &quot;Toney&quot;,
                  &quot;surname&quot;: &quot;Stark&quot;
            },
            {
                  &quot;displayName&quot;: &quot;James Martin&quot;,
                  &quot;givenName&quot;: &quot;James&quot;,
                  &quot;surname&quot;: &quot;Martin&quot;
            }
      ]
}

Please help me out in this.

是的,如果您创建一个名为"Users"的模型类,并正确映射它以及其属性,那么它将与您在截图中显示的内容完全一样。

以下是已经翻译好的部分:

"如果添加一个包装类并将其转换为JSON将会很容易。"

import java.util.List;

public class UserWrap {
    private List<User> users;

    public UserWrap(List<User> users) {
        this.users = users;
    }
}
英文:

It would be easy if add a wrap class and convert it to json

import java.util.List;

public class UserWrap {
    private List&lt;User&gt; users;

    public UserWrap(List&lt;User&gt; users) {
        this.users = users;
    }
}
