Question

我正在尝试使用Gson将此测试json字符串加载到对象中，但每个元素都带有null。转换期间没有触发异常。请让我知道我可能做错了什么。感谢您的帮助。

我在这里写一篇较长的评论只是因为没有写出足够的文字来询问我的查询而引发错误。我无法想象为什么会这样做。

String testSeg1 = "{\"FlightSegment\":{\"discount\":0,\"childTaxBreakup\":\"0,0,0\",\"adultTaxBreakup\":\"0,154,413\",\"viaFlight\":\"\",\"airportTaxInfant\":0,\"OperatingAirlineFlightNumber\":144,\"StopQuantity\":0,\"BookingClass\":{\"Availability\":9,\"ResBookDesigCode\":\"S\"},\"AirEquipType\":\"77W\",\"RPH\":\"\",\"airportTax\":567,\"airportTaxChild\":0,\"OperatingAirlineCode\":\"AI\",\"DepartureDateTime\":\"2017-11-27T17:00:00\",\"ArrivalDateTime\":\"2017-11-27T19:10:00\",\"imageFileName\":\"http://live.arzoo.com/FlightWS/image/AirIndia.gif\",\"FlightNumber\":144,\"airLineName\":\"Air India\",\"DepartureAirportCode\":\"BOM\",\"octax\":0,\"ArrivalAirportCode\":\"DEL\",\"BookingClassFare\":{\"bookingclass\":\"S\",\"adultFare\":3955,\"commissionOnTCharge\":0,\"farebasiscode\":\"glW5J3cLgtM=\",\"Rule\":\"This fare is Non Refundable <br> Baggage : 25K<br>Booking Class : S|Re-Schedule Charges: Rs. 750 per sector + Fare difference (If any) +admin fee 500 + Service Fee of Rs. 250 Sector .|Cancellation Charges : Basic fare +Airline administration fee 500  + Service Charges 250 Per Passenger Per Sector .\\t\\t\\t\\t\\t    |\",\"adultCommission\":0,\"childCommission\":0,\"classType\":\"Economy\"},\"infantTaxBreakup\":\"0,0,0\"}}";

Answer 1

请勿使用TypeToken，因为您没有加载对象列表，请直接使用该类：

FlightSegment testFlt = gson.fromJson(testSeg1, FlightSegment.class);

Java - 无法将json字符串加载到对象，每个元素都为null
