根据节点列表构造树代码的prompt

根据给定的数据结构和数据，写构造树状结构的java 代码，90% 可用。在通义千问，智谱 AI 测试良好。

下面的<json>是一个树状节点的列表，<code>定义了节点的类，parentId表示上级节点的ID，请写一个java方法把它整理成树状结构。 
<code> 
public class TreeNodeVO {
    private Long id;
    private Long appId;
    private String tagName;
    private Long parentId;
    private String idPath;
    private JSONObject extInfo;
    private Long status;
    @JsonFormat(timezone = "GMT+8", pattern = "yyyy-MM-dd HH:mm:ss")
    private Date createdTime;
    private List<TreeNodeVO> children;
}
</code>

<json> 
[ { "id": 2, "appId": 1, "tagName": "C", "parentId": 1, "idPath": "1/", "extInfo": "{}", "status": 1, "createdTime": "2024-03-19 08:01:43" }, { "id": 3, "appId": 1, "tagName": "D", "parentId": 2, "idPath": "1/2/", "extInfo": "{}", "status": 1, "createdTime": "2024-03-19 18:44:27" }, { "id": 4, "appId": 1, "tagName": "E", "parentId": 3, "idPath": "1/2/3/", "extInfo": "{}", "status": 1, "createdTime": "2024-03-20 09:34:49" } ]
</json>
