List of fromMessage() Examples

Examples of fromMessage()

org.springframework.amqp.support.converter.JsonMessageConverter.fromMessage()
org.springframework.amqp.support.converter.MessageConverter.fromMessage()
Convert from a Message to a Java object. @param message the message to convert @return the converted Java object @throws MessageConversionException in case of conversion failure
org.springframework.amqp.support.converter.SimpleMessageConverter.fromMessage()
Converts from a AMQP Message to an Object.
org.springframework.jms.support.converter.MessageConverter.fromMessage()
Convert from a JMS Message to a Java object. @param message the message to convert @return the converted Java object @throws javax.jms.JMSException if thrown by JMS API methods @throws MessageConversionException in case of conversion failure
org.springframework.jms.support.converter.SimpleMessageConverter.fromMessage()
This implementation converts a TextMessage back to a String, a ByteMessage back to a byte array, a MapMessage back to a Map, and an ObjectMessage back to a Serializable object. Returns the plain Message object in case of an unknown message type. @see #extractStringFromMessage @see #extractByteArrayFromMessage @see #extractMapFromMessage @see #extractSerializableFromMessage
org.springframework.jms.support.converter.SimpleMessageConverter102.fromMessage()
org.springframework.messaging.converter.CompositeMessageConverter.fromMessage()
org.springframework.messaging.converter.MessageConverter.fromMessage()
Convert the payload of a {@link Message} from serialized form to a typed Object ofthe specified target class. The {@link MessageHeaders#CONTENT_TYPE} header shouldindicate the MIME type to convert from.
If the converter does not support the specified media type or cannot perform the conversion, it should return {@code null}. @param message the input message @param targetClass the target class for the conversion @return the result of the conversion, or {@code null} if the converter cannotperform the conversion

Examples of org.springframework.messaging.converter.CompositeMessageConverter.fromMessage()

    assertEquals(MimeType.valueOf("application/x-java-serialized-object"),
        result.getHeaders().get(MessageHeaders.CONTENT_TYPE));


    // Now convert back
    converter = converterFactory.newInstance(MimeType.valueOf("application/x-java-object"));
    result = (Message<?>) converter.fromMessage(result, Foo.class);
    assertNotNull(result);
    assertTrue(result.getPayload() instanceof Foo);
    assertEquals(MimeType.valueOf("application/x-java-object;type=" + Foo.class.getName()),
        result.getHeaders().get(MessageHeaders.CONTENT_TYPE));
  }
