我正在使用Jackson将json数组反序列化为一些对象。这是我的课:publicclassOfferContainerextendsActiveRecordBase{publicOfferoffer;publicOfferContainer(){}publicOfferContainer(Databasedb){super(db);}@OverridepublicStringtoString(){returnthis.getID()+offer.toString();}publicStringgetDescription(){returnoffer.description;}publ
我需要将json转换为POJO,为此我决定使用JACKSON库,我已将jackson-databind-2.2.3.jar和jackson-core-2.0.6.jar添加到我的路径然后创建了以下类:1-数据绑定(bind)类:packageDistributed;importjava.io.IOException;importjava.net.MalformedURLException;importjava.net.URL;importcom.fasterxml.jackson.core.JsonParseException;importcom.fasterxml.jackson.d

我正在使用JacksonPolymorphicDeserialization,这是我的代码,它根据“类型”属性反序列化为适当的类:@JsonTypeInfo(use=JsonTypeInfo.Id.NAME,include=JsonTypeInfo.As.PROPERTY,property="type",defaultImpl=Event.class,visible=true)@JsonSubTypes({@Type(value=SpecialEvent1.class,name="SPECIAL_EVENT_1"),@Type(value=SpecialEvent2.class,nam
