Class SerializerMessageConverter

java.lang.Object

org.springframework.amqp.support.converter.AbstractMessageConverter

org.springframework.amqp.support.converter.AllowedListDeserializingMessageConverter

org.springframework.amqp.support.converter.SerializerMessageConverter

All Implemented Interfaces:

MessageConverter

public class SerializerMessageConverter
extends AllowedListDeserializingMessageConverter

Implementation of MessageConverter that can work with Strings or native objects of any kind via the Serializer and Deserializer abstractions in Spring. The AbstractMessageConverter.toMessage(Object, MessageProperties) method simply checks the type of the provided instance while the fromMessage(Message) method relies upon the content-type of the provided Message.

If a DefaultDeserializer is configured (default), the allowed patterns will be applied (if configured); for all other deserializers, the deserializer is responsible for checking classes, if necessary.

Method Detail

setIgnoreContentType

public void setIgnoreContentType(boolean ignoreContentType)

Flag to signal that the content type should be ignored and the deserializer used irrespective if it is a text message. Defaults to false, in which case the default encoding is used to convert a text message to a String.

Parameters:

ignoreContentType - the flag value to set

setDefaultCharset

public void setDefaultCharset(String defaultCharset)

Specify the default charset to use when converting to or from text-based Message body content. If not specified, the charset will be "UTF-8".

Parameters:

defaultCharset - The default charset.

setSerializer

public void setSerializer(Serializer<Object> serializer)

The serializer to use for converting Java objects to message bodies.

Parameters:

serializer - the serializer to set

setDeserializer

public void setDeserializer(Deserializer<Object> deserializer)

The deserializer to use for converting from message body to Java object.

Parameters:

deserializer - the deserializer to set

fromMessage

public Object fromMessage(Message message)
                   throws MessageConversionException

Converts from a AMQP Message to an Object.

Parameters:

message - the message to convert

Returns:

the converted Java object

Throws:

MessageConversionException - in case of conversion failure

createMessage

protected Message createMessage(Object object,
                                MessageProperties messageProperties)
                         throws MessageConversionException

Creates an AMQP Message from the provided Object.

Specified by:

createMessage in class AbstractMessageConverter

Parameters:

object - the payload.

messageProperties - the message properties (headers).

Returns:

a message.

Throws:

MessageConversionException
