你提供的原始数据结构是一个嵌套的 JSON 对象，其中包含 `x` 坐标轴数据和 `y` 中多个带有 `name` 和 `ratio` 的数据项。你需要将其转换为如下格式： ```json { "dimName": "{dimName}", "title": "{title}", "x": "[所提取的x数据]", "data": { "{y}中的{name}": [对应 ratio 数据] } } ``` --- ### ✅ 转换逻辑说明 1. **提取字段**： - `dimName`：直接从原始对象中获取； - `title`：直接从原始对象中获取； - `x`：来自 `map.x`； - `data`：将 `map.y` 中的每个对象的 `name` 作为键，其 `ratio` 数组作为值。 2. **目标结构示例**（简化）： ```json { "dimName": "模型分值", "title": "提升效果", "x": ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10"], "data": { "2024 - 求和项:CUR_REAL_ANP_ADJ": [0.215, 0.127, ..., 0.0607], "2024 - 求和项:PLR": [0.4833, 0.5622, ..., 1.0385], "2024 - 求和项:LR": [0.4237, 0.4333, ..., 0.8478] } } ``` --- ### ✅ Java代码实现（使用 FastJSON） ```java import com.alibaba.fastjson.*; import java.util.*; public class JsonDataTransformer { public static void main(String[] args) { String jsonData = "{\"dimName\":\"模型分值\",\"echatsName\":\"私家车燃油车\",\"map\":{\"x\":[\"1\",\"2\",\"3\",\"4\",\"5\",\"6\",\"7\",\"8\",\"9\",\"10\"],\"y\":[{\"name\":\"2024 - 求和项:CUR_REAL_ANP_ADJ\",\"ratio\":[0.215,0.127,0.1083,0.0989,0.0899,0.0819,0.0763,0.0715,0.0665,0.0607],\"type\":\"1\"},{\"name\":\"2024 - 求和项:PLR\",\"ratio\":[0.4833,0.5622,0.6001,0.6325,0.6656,0.7,0.7401,0.7892,0.8639,1.0385],\"type\":\"3\"},{\"name\":\"2024 - 求和项:LR\",\"ratio\":[0.4237,0.4333,0.6267,0.5871,0.5951,0.6223,0.837,0.8298,0.6898,0.8478],\"type\":\"2\"}],\"issueMonth\":[\"2024 - 求和项:CUR_REAL_ANP_ADJ\",\"2024 - 求和项:PLR\",\"2024 - 求和项:LR\"]},\"title\":\"提升效果\",\"type\":\"2\"}"; JSONObject original = JSON.parseObject(jsonData); JSONObject map = original.getJSONObject("map"); // 提取 x 轴数据 List<String> xList = map.getJSONArray("x").toJavaList(String.class); // 提取 y 数据 JSONArray yArray = map.getJSONArray("y"); Map<String, List<Double>> dataMap = new LinkedHashMap<>(); for (Object obj : yArray) { JSONObject item = (JSONObject) obj; String name = item.getString("name"); List<Double> ratio = item.getJSONArray("ratio").toJavaList(Double.class); dataMap.put(name, ratio); } // 构建结果 JSONObject result = new JSONObject(); result.put("dimName", original.getString("dimName")); result.put("title", original.getString("title")); result.put("x", xList); JSONObject dataObj = new JSONObject(); for (Map.Entry<String, List<Double>> entry : dataMap.entrySet()) { dataObj.put(entry.getKey(), entry.getValue()); } result.put("data", dataObj); System.out.println(result.toJSONString()); } } ``` --- ### ✅ 依赖要求 同样使用阿里巴巴的 `FastJSON`，请确保引入以下 Maven 依赖： ```xml <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.83</version> </dependency> ``` --- ### ✅ 输出结果示例 ```json { "dimName": "模型分值", "title": "提升效果", "x": ["1","2","3","4","5","6","7","8","9","10"], "data": { "2024 - 求和项:CUR_REAL_ANP_ADJ": [0.215, 0.127, 0.1083, 0.0989, 0.0899, 0.0819, 0.0763, 0.0715, 0.0665, 0.0607], "2024 - 求和项:PLR": [0.4833, 0.5622, 0.6001, 0.6325, 0.6656, 0.7, 0.7401, 0.7892, 0.8639, 1.0385], "2024 - 求和项:LR": [0.4237, 0.4333, 0.6267, 0.5871, 0.5951, 0.6223, 0.837, 0.8298, 0.6898, 0.8478] } } ``` --- ###
