                                     JsonProcessingException

Method called when a JSON property is encountered that has not matching setter, any-setter or field, and thus can not be assigned.

覆盖:

handleUnknownProperty 在类中 StdDeserializer<Object>

参数:

jp - Parser that points to value of the unknown property

ctxt - Context for deserialization; allows access to the parser, error reporting functionality

beanOrClass - Instance that is being populated by this deserializer, or if not known, Class that would be instantiated. If null, will assume type is what StdDeserializer.getValueClass() returns.

propName - Name of the property that can not be mapped

IOException

wrapAndThrow

public void wrapAndThrow(Throwable t,

                  throws IOException

Method that will modify caught exception (passed in as argument) as necessary to include reference information, and to ensure it is a subtype of IOException, or an unchecked exception.

Rules for wrapping and unwrapping are bit complicated; essentially:

• Errors are to be passed as is (if uncovered via unwrapping)
• "Plain" IOExceptions (ones that are not of type JsonMappingException are to be passed as is
