Answer 1

您可以扩展 com.fasterxml.jackson.databind.PropertyNamingStrategy 并覆盖翻译方法并执行如下操作：

public static class UpperCaseJsonStrategy extends PropertyNamingStrategyBase {
    @Override
    public String translate(String input) {
        return str.charAt(0).toUpperCase() + str.slice(1);
    }
}

Answer 2

List<Map> panicData = new ArrayList<Map>();
    ResultSet rs = stm.executeQuery(query1);
                while (rs.next()) {
                    Map<Object, Object>hsa=new HashMap<Object,Object>();
                    String VehicleNumber=rs.getString(1);
                    String Address=rs.getString(2);
                    Double Latitude=rs.getDouble(3);
                    Double Longitude=rs.getDouble(4);
                    String Alerttime=rs.getString(5);
                    int spd=rs.getInt(6);
                    String Speed=spd+"";
                    hsa.put("VehicleNumber",VehicleNumber);
                    hsa.put("Address", Address);
                    hsa.put("Latitude", Latitude);
                    hsa.put("Longitude", Longitude);
                    hsa.put("Alerttime", Alerttime);
                    hsa.put("Speed",Speed);
                    
                    panicData.add(hsa);
                }
            }
