Class MappingJacksonMessageConverter

java.lang.Object

org.springframework.jms.support.converter.MappingJacksonMessageConverter

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanClassLoaderAware, MessageConverter

Deprecated.

Please migrate to MappingJackson2MessageConverter for Jackson 2.x.

@Deprecated
public class MappingJacksonMessageConverter
extends Object
implements MessageConverter, org.springframework.beans.factory.BeanClassLoaderAware

Message converter that uses Jackson 1.x to convert messages to and from JSON. Maps an object to a BytesMessage, or to a TextMessage if the targetType is set to MessageType.TEXT. Converts from a TextMessage or BytesMessage to an object.

NOTE: Requires Jackson 1.8 or higher, as of Spring 4.0. At the same time, we strongly recommend a migration to Jackson 2.x!

Since:

3.1

Field Detail

DEFAULT_ENCODING

public static final String DEFAULT_ENCODING

Deprecated.

The default encoding used for writing to text messages: UTF-8.

Constant Field Values

Constructor Detail

MappingJacksonMessageConverter

public MappingJacksonMessageConverter()

Deprecated.

Method Detail

setObjectMapper

public void setObjectMapper(ObjectMapper objectMapper)

Deprecated.

Specify the ObjectMapper to use instead of using the default.

setTargetType

public void setTargetType(MessageType targetType)

Deprecated.

Specify whether toMessage(Object, Session) should marshal to a BytesMessage or a TextMessage.

The default is MessageType.BYTES, i.e. this converter marshals to a BytesMessage. Note that the default version of this converter supports MessageType.BYTES and MessageType.TEXT only.

See Also:

MessageType.BYTES, MessageType.TEXT

setEncoding

public void setEncoding(String encoding)

Deprecated.

Specify the encoding to use when converting to and from text-based message body content. The default encoding will be "UTF-8".

When reading from a a text-based message, an encoding may have been suggested through a special JMS property which will then be preferred over the encoding set on this MessageConverter instance.

See Also:

setEncodingPropertyName(java.lang.String)

setEncodingPropertyName

public void setEncodingPropertyName(String encodingPropertyName)

Deprecated.

Specify the name of the JMS message property that carries the encoding from bytes to String and back is BytesMessage is used during the conversion process.

Default is none. Setting this property is optional; if not set, UTF-8 will be used for decoding any incoming bytes message.

See Also:

setEncoding(java.lang.String)

setTypeIdPropertyName

public void setTypeIdPropertyName(String typeIdPropertyName)

Deprecated.

Specify the name of the JMS message property that carries the type id for the contained object: either a mapped id value or a raw Java class name.

Default is none. NOTE: This property needs to be set in order to allow for converting from an incoming message to a Java object.

See Also:

setTypeIdMappings(java.util.Map<java.lang.String, java.lang.Class<?>>)

setTypeIdMappings

public void setTypeIdMappings(Map<String,Class<?>> typeIdMappings)

Deprecated.

Specify mappings from type ids to Java classes, if desired. This allows for synthetic ids in the type id message property, instead of transferring Java class names.

Default is no custom mappings, i.e. transferring raw Java class names.

Parameters:

typeIdMappings - a Map with type id values as keys and Java classes as values

Deprecated.

Determine a Jackson JavaType for the given JMS Message, typically parsing a type id message property.

The default implementation parses the configured type id property name and consults the configured type id mapping. This can be overridden with a different strategy, e.g. doing some heuristics based on message origin.

JMSException - if thrown by JMS methods
