封闭类:

StdDeserializerProvider

protected static final class StdDeserializerProvider.WrappedDeserializer
extends JsonDeserializer<Object>

Simple deserializer that will call configured type deserializer, passing in configured data deserializer, and exposing it all as a simple deserializer.

从类复制的说明: JsonDeserializer

Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles. Returned instance is to be constructed by method itself.

Pre-condition for this method is that the parser points to the first event that is part of value to deserializer (and which is never JSON 'null' literal, more on this below): for simple types it may be the only value; and for structured types the Object start marker. Post-condition is that the parser will point to the last event that is part of deserialized value (or in case deserialization fails, event that was not recognized or usable, which may be the same event as the one it pointed to upon call).

Note that this method is never called for JSON null literal, and thus deserializers need (and should) not check for it.

指定者:

deserialize 在类中 JsonDeserializer<Object>

参数:

jp - Parsed used for reading JSON content

ctxt - Context that can be used to access information about this deserialization activity.

返回:

Deserializer value

抛出:

IOException

JsonProcessingException

deserializeWithType

public Object deserializeWithType(JsonParser jp,
                         DeserializationContext ctxt,
                         TypeDeserializer typeDeserializer)
                           throws IOException,
                                  JsonProcessingException

从类复制的说明: JsonDeserializer

Deserialization called when type being deserialized is defined to contain additional type identifier, to allow for correctly instantiating correct subtype. This can be due to annotation on type (or its supertype), or due to global settings without annotations.

Default implementation may work for some types, but ideally subclasses should not rely on current default implementation. Implementation is mostly provided to avoid compilation errors with older code.

覆盖:

deserializeWithType 在类中 JsonDeserializer<Object>

typeDeserializer - Deserializer to use for handling type information

抛出:

IOException

JsonProcessingException
