我不明白双向关系反序列化有什么问题:
序列化注册是:
{
uuid: "d3372f25-ac70-4735-b756-7894977142b2",
payment: [{
"uuid":"15363b3f-7057-4658-3f63-3f3f695d7019",
"type":0,
"amount":10
"registration":"d3372f25-ac70-4735-b756-7894977142b2"
},
{
"uuid":"ee9fb135-2b21-48f4-a1ee-2f71f09f44ab",
"type":0,
"amount":5
"registration":"d3372f25-ac70-4735-b756-7894977142b2"
}]
}
Java是:
@JsonIdentityInfo(
generator = ObjectIdGenerators.PropertyGenerator.class,
property = "uuid", scope = Registration.class)
public class Registration implements Serializable {}
@JsonIdentityInfo(
generator = ObjectIdGenerators.PropertyGenerator.class,
property = "uuid", scope = Payment.class)
public class Payment implements Serializable {}
无法读取文件:已经有id的POJO(java.util.UUID)[[ObjectId:key = d3372f25-ac70-4735-b756-7894977142b2,type = com.fasterxml.jackson.databind.deser.impl。 PropertyBasedObjectIdGenerator,scope = com.mezoo.tdc.model.Registration]](通过引用链:com.mezoo.tdc.model.Registration [“payment”] - > java.util.ArrayList [0] - > com。 mezoo.tdc.model.Payment [ “注册”] - > com.mezoo.tdc.model.Registration [ “的uuid”]);嵌套异常是com.fasterxml.jackson.databind.JsonMappingException:已经有id的POJO(java.util.UUID)[[ObjectId:key = d3372f25-ac70-4735-b756-7894977142b2,type = com.fasterxml.jackson.databind .deser.impl.PropertyBasedObjectIdGenerator,scope = com.mezoo.tdc.model.Registration]](通过引用链:com.mezoo.tdc.model.Registration [“payment”] - > java.util.ArrayList [0] - > com.mezoo.tdc.model.Payment [ “注册”] - > com.mezoo.tdc.model.Registration [ “的uuid”])“
有人可以向我解释为什么反序列化不起作用吗?
