[英]JSON to Java Object Mapping , needed for Spring REST
我正在通过REST API调用获取以下JSON对象，并且我希望能够在结果JSON数组中选取信息，并在POJO中将其转换为例如ExchangeListInfo，RedeemCall ... IncomeInformation仅
我如何使用Jackson 1-9.0 API做到这一点，我也写了一些代码片段，但我似乎无法弄清楚如何使映射在这种复杂的情况下可以正常工作，感谢您的帮助。

您的JSON数据映射到ResultWrapper Pojo，如下所示，现在您可以根据需要在ResultWrapper上迭代结果，并能够选择任何实体/对象。
Result result = resultWrapper.getResults().get(0)
ExchangeListInfo exchangeListInfo = result.getExchangeListInfo();
RedeemCall redeemCall = result.getRedeemCall(); //etc
在这里使用了JsonToPojo工具 ，得到了以下内容，您的主要Pojo是ResultWrapper ，为了简洁起见，省略了一些导入
