getDeserializer

public static JsonDeserializer<? extends JsonNode> getDeserializer(Class<?> nodeClass)

Factory method for accessing deserializer for specific node type

deserialize

public JsonNode deserialize(JsonParser jp,
                   DeserializationContext ctxt)
                     throws IOException,
                            JsonProcessingException

Implementation that will produce types of any JSON nodes; not just one deserializer is registered to handle (in case of more specialized handler). Overridden by typed sub-classes for more thorough checking

指定者:

deserialize 在类中 JsonDeserializer<JsonNode>

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: StdDeserializer

Base implementation that does not assume specific type inclusion mechanism. Sub-classes are expected to override this method if they are to handle type information.

覆盖:

deserializeWithType 在类中 StdDeserializer<N extends JsonNode>

typeDeserializer - Deserializer to use for handling type information

抛出:

IOException

JsonProcessingException

_reportProblem

protected void _reportProblem(JsonParser jp,
                  String msg)
                       throws JsonMappingException

抛出:

JsonMappingException

_handleDuplicateField

protected void _handleDuplicateField(String fieldName,
                         ObjectNode objectNode,
                         JsonNode oldValue,
                         JsonNode newValue)
                              throws JsonProcessingException

Method called when there is a duplicate value for a field. By default we don't care, and the last value is used. Can be overridden to provide alternate handling, such as throwing an exception, or choosing different strategy for combining values or choosing which one to keep.

参数:

fieldName - Name of the field for which duplicate value was found

objectNode - Object node that contains values

oldValue - Value that existed for the object node before newValue was added

newValue - Newly added value just added to the object node

抛出:

JsonProcessingException

deserializeObject

protected final ObjectNode deserializeObject(JsonParser jp,
                           DeserializationContext ctxt,
                           JsonNodeFactory nodeFactory)
                                      throws IOException,
                                             JsonProcessingException

抛出:

IOException

JsonProcessingException

deserializeArray

protected final ArrayNode deserializeArray(JsonParser jp,
                         DeserializationContext ctxt,
                         JsonNodeFactory nodeFactory)
                                    throws IOException,
                                           JsonProcessingException

抛出:

IOException

JsonProcessingException

deserializeAny

protected final JsonNode deserializeAny(JsonParser jp,
                      DeserializationContext ctxt,
                      JsonNodeFactory nodeFactory)
                                 throws IOException,
                                        JsonProcessingException

抛出:
