无法解析嵌套 json 和更改响应结构

Question

我在解析 json 并稍微更改响应结构时遇到问题。下面是我正在尝试解析的 json -

{
  "subRecords": [
    {
      "row": [
        {
          "practice": [
            {
              "addressId": "123",
              "name":"JON"
     
            }
          ]
        }
      ],
      "Key": "123456-ABC"
    }
  ]
}

我的预期输出是没有 row -

{
  "subRecords": [
    {
      "practice": [
        {
          "addressId": "123",
          "name": "JON"
        }
      ],
      "Key": "123456-ABC"
    }
  ]
}

下面是我的pojo -

@Getter
@Setter
@ToString
@JsonInclude(JsonInclude.Include.NON_NULL)
public class Test{
     private Map<String,Object>Key;
    
    private List<Map<String,Object>>practice;
    
        private List<Map<String, Object>> subRecords;
    
    
        public List<Map<String, Object>> getSubRecords() {
            return subRecords;
        }
    
        public void setSubRecords(List<Map<String, Object>> row) {
    
           this.practice= (List<Map<String, Object>>) row.get(0).get("practice");
        }
}

但我不断收到如下解析错误-

 "errors": {
        "status": "500",
        "title": "Internal Server Error",
        "detail": "N/A\n at [Source: (String)\

我不确定我是否正确访问 json 我将不胜感激任何帮助。

要将第一个 JSON 解析为 Java 对象，您需要以下数据模型：

public class Original {
    private List<OriginalSubRecords> subRecords;
}

public class OriginalSubRecords {
    private OriginalSubRecordsRow row;
    private String Key;
}

public class OriginalSubRecordsRow {
    private List<OriginalSubRecordsRowPractice> practice;
}

public class OriginalSubRecordsRowPractice {
    private String addressId;
    private String name;
}

然后您需要使用以下数据模型将 Original 映射到 Restructured 对象：

public class Restructured {
    private List<RestructuredSubRecords> subRecords;
}

public class RestructuredSubRecords {
    private List<RestructuredSubRecordsPractice> practice;
    private String Key;
}

public class RestructuredSubRecordsPractice {
    private String addressId;
    private String name;
}

映射它们非常简单，唯一的细节是您似乎只对 row 中的第一个 practice 感兴趣。
