Class JsonMappingException

java.lang.Object
  java.lang.Throwable
      java.lang.Exception
          java.io.IOException
              com.fasterxml.jackson.core.JsonProcessingException
                  com.fasterxml.jackson.databind.JsonMappingException

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

InvalidFormatException, UnrecognizedPropertyException

public class JsonMappingException
extends JsonProcessingException

Checked exception used to signal fatal problems with mapping of content.

One additional feature is the ability to denote relevant path of references (during serialization/deserialization) to help in troubleshooting.

JsonMappingException

public JsonMappingException(String msg,
                            JsonLocation loc,

Method Detail

from

public static JsonMappingException from(JsonParser jp,
                                        String msg)

from

public static JsonMappingException from(JsonParser jp,
                                        String msg,
                                        Throwable problem)

fromUnexpectedIOE

public static JsonMappingException fromUnexpectedIOE(IOException src)

Factory method used when "upgrading" an IOException into JsonMappingException: usually only needed to comply with a signature.

Since:

2.1

wrapWithPath

public static JsonMappingException wrapWithPath(Throwable src,
                                                Object refFrom,
                                                String refFieldName)

Method that can be called to either create a new JsonMappingException (if underlying exception is not a JsonMappingException), or augment given exception with given path/reference information. This version of method is called when the reference is through a non-indexed object, such as a Map or POJO/bean.

wrapWithPath

public static JsonMappingException wrapWithPath(Throwable src,
                                                Object refFrom,
                                                int index)

Method that can be called to either create a new JsonMappingException (if underlying exception is not a JsonMappingException), or augment given exception with given path/reference information. This version of method is called when the reference is through an index, which happens with arrays and Collections.

wrapWithPath

public static JsonMappingException wrapWithPath(Throwable src,
                                                JsonMappingException.Reference ref)

Method that can be called to either create a new JsonMappingException (if underlying exception is not a JsonMappingException), or augment given exception with given path/reference information.

getPath

public List<JsonMappingException.Reference> getPath()

Method for accessing full structural path within type hierarchy down to problematic property.

getPathReference

public String getPathReference()

Method for accesing description of path that lead to the problem that triggered this exception

getPathReference

public StringBuilder getPathReference(StringBuilder sb)

prependPath

public void prependPath(Object referrer,
                        String fieldName)

Method called to prepend a reference information in front of current path

prependPath

public void prependPath(Object referrer,
                        int index)

Method called to prepend a reference information in front of current path

prependPath

public void prependPath(JsonMappingException.Reference r)

getLocalizedMessage

public String getLocalizedMessage()

Overrides:

getLocalizedMessage in class Throwable

getMessage

public String getMessage()

Method is overridden so that we can properly inject description of problem path, if such is defined.

Overrides:

getMessage in class JsonProcessingException

_buildMessage

protected String _buildMessage()

toString

public String toString()

Overrides:

toString in class JsonProcessingException

_appendPathDesc

protected void _appendPathDesc(StringBuilder sb)
