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：

  1. {
  2.   "displayName": "Tony Stark",
  3.   "givenName": "Tony",
  4.   "surname": "Stark"
  5. },
  6. {
  7.   "displayName": "James Martin",
  8.   "givenName": "James",
  9.   "surname": "Martin"
  10. }

我需要像这样的格式：

  1. {
  2.    "users": 
  3.       [
  4.             {
  5.                   "displayName": "Tony Stark",
  6.                   "givenName": "Toney",
  7.                   "surname": "Stark"
  8.             },
  9.             {
  10.                   "displayName": "James Martin",
  11.                   "givenName": "James",
  12.                   "surname": "Martin"
  13.             }
  14.       ]
  15. }

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"

  1. {
  2.   &quot;displayName&quot;: &quot;Tony Stark&quot;,
  3.   &quot;givenName&quot;: &quot;Tony&quot;,
  4.   &quot;surname&quot;: &quot;Stark&quot;
  5. },
  6. {
  7.   &quot;displayName&quot;: &quot;James Martin&quot;,
  8.   &quot;givenName&quot;: &quot;James&quot;,
  9.   &quot;surname&quot;: &quot;Martin&quot;
  10. }

I need something like this:

  1. {
  2.    &quot;users&quot;: 
  3.       [
  4.             {
  5.                   &quot;displayName&quot;: &quot;Tony Stark&quot;,
  6.                   &quot;givenName&quot;: &quot;Toney&quot;,
  7.                   &quot;surname&quot;: &quot;Stark&quot;
  8.             },
  9.             {
  10.                   &quot;displayName&quot;: &quot;James Martin&quot;,
  11.                   &quot;givenName&quot;: &quot;James&quot;,
  12.                   &quot;surname&quot;: &quot;Martin&quot;
  13.             }
  14.       ]
  15. }

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。"

  1. import java.util.List;
  3. public class UserWrap {
  4.     private List<User> users;
  6.     public UserWrap(List<User> users) {
  7.         this.users = users;
  8.     }
  9. }
英文:

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

  1. import java.util.List;
  3. public class UserWrap {
  4.     private List&lt;User&gt; users;
  6.     public UserWrap(List&lt;User&gt; users) {
  7.         this.users = users;
  8.     }
  9. }
