我通过REST API调用获取以下JSON对象，我希望能够在结果JSON数组中选择信息，并在POJO中转换相同的信息，例如ExchangeListInfo，RedeemCall ...仅收入信息
我如何使用Jackson 1-9.0 api完成这项工作，我已经编写了一些代码片段，但我似乎无法弄清楚如何让映射在这个复杂的场景中工作，感谢任何帮助

答案 0 :(得分：2)
您的JSON数据映射到ResultWrapper Pojo，如下所示，现在您可以根据需要对ResultWrapper上的结果进行迭代，并且能够选择任何实体/对象
例如。
Result result = resultWrapper.getResults().get(0)
ExchangeListInfo exchangeListInfo = result.getExchangeListInfo();
RedeemCall redeemCall = result.getRedeemCall(); //etc
使用JsonToPojo toool here并获得以下内容，您的主要Pojo为ResultWrapper，为简洁而省略了一些导入
