Java 基于类反序列化json时发生异常，该类内部有接口类型

您可以将其映射到地图列表，然后使用BeanMapper（如获取更多信息的错误消息）

您可以给出更详细的说明吗？谢谢你能给我一些更详细的说明吗？谢谢 JSON file { "serviceURL": "com.mycompany.serviceURL", "dealerAttributes": [ { "language": "language0", "dealerAttributeName": "dealerAttributeName0", "updateDate": 0 }, { "language": "language1", "dealerAttributeName": "dealerAttributeName1", "updateDate": 1 } ] } class Dealer { private String serviceURL; private List dealerAttributes; public Dealer() { dealerAttributes = new ArrayList(); } //Getters and Setters... } public interface IDealerAttributes { public String getLanguage(); public String getDealerAttributeName(); public long getUpdateDate(); } gson.fromJson(jsonObj.toString(), Dealer.class); Exception unmarshalling json String into Object: com.google.gson.JsonParseException: The JsonDeserializer com.google.gson.DefaultTypeAdapters$CollectionTypeAdapter@60e26ffd failed to deserialize json object [{"language":"language0","dealerAttributeName":"dealerAttributeName0","updateDate":0},{"language":"language1","dealerAttributeName":"dealerAttributeName1","updateDate":1}] given the type java.util.List public class DealerAttributes implements IDealerAttributes { private String language; private String dealerAttributeName; private long updateDate; public DealerAttributes() { } //Getters and Setters... }

gson.registerTypeAdapter(MyType.class, new MyType());`
