post提交：

{"tableName":"（表名）","field":"（列名）","where":"（查詢條件）","DBJson":{"url":"jdbc:（資料庫地址）?characterEncoding=UTF-8" ,"username":"","password":""}}

所獲取的列的形式：

{"success":"true","detail":{"check":"X50380缺失”,"code":"002","result":[{"notHappenProbability":0.99203277,"rejectionRate":0.6595714,"score":65.957146,"trainDataVersion":"100"}]}}

目的：獲取json中的score對應的分值

java程式碼：

String url= params.get("body").replaceAll("%(?![0-9a-fA-F]{2})", "%25"); 
param = URLDecoder.decode(url, "utf-8").trim();
JSONObject json=JSONObject.fromObject(param);

String dataName = json.getString("tableName");
String where = json.getString("where");
BatchService batchService = (BatchService)MyBeanFactory.getService("batchService");
JSONObject DBJson=json.getJSONObject("DBJson");
String field=json.getString("field");
List<JSONObject> findtPayment = batchService.findtPayment(dataName, where, DBJson);

List<String> ScoreList=new ArrayList<>();

               for(JSONObject jParam:findtPayment){
final JSONObject jsonObject= jParam.getJSONObject(field).has("params")? 
jParam.getJSONObject(field).getJSONObject("params"):jParam.getJSONObject(field);
  
if (jsonObject.getString("success").equals("true")) {
JSONObject detail=jsonObject.getJSONObject("detail");

if (detail.has("result")) {
JSONArray resultArray=detail.getJSONArray("result");
for(int i=0;i<resultArray.size();i++){
JSONObject object=resultArray.getJSONObject(i);
String score=object.getString("score");
ScoreList.add(score);
}
}
  }

}

注意：根據json格式寫判斷條件，我的json列裡面有打分不成功的情況，並且success=true之後還有可能出現打分失敗沒有result的情況，所以添加了判斷條件。
