    }
}

Example 2 with MessageConverter

use of org.springframework.amqp.support.converter.MessageConverter in project spring-integration by spring-projects.

the class ChannelTests method messageConversionTests.

@Test
public void messageConversionTests() throws Exception {
    RabbitTemplate amqpTemplate = new RabbitTemplate(this.connectionFactory);
    MessageConverter messageConverter = mock(MessageConverter.class);
    amqpTemplate.setMessageConverter(messageConverter);
    PointToPointSubscribableAmqpChannel channel = new PointToPointSubscribableAmqpChannel("testConvertFail", new SimpleMessageListenerContainer(this.connectionFactory), amqpTemplate);
    channel.afterPropertiesSet();
    MessageListener listener = TestUtils.getPropertyValue(channel, "container.messageListener", MessageListener.class);
    willThrow(new MessageConversionException("foo", new IllegalStateException("bar"))).given(messageConverter).fromMessage(any(org.springframework.amqp.core.Message.class));
    this.exception.expect(MessageConversionException.class);
    this.exception.expectCause(instanceOf(IllegalStateException.class));
    listener.onMessage(mock(org.springframework.amqp.core.Message.class));
}

Example 3 with MessageConverter

use of org.springframework.amqp.support.converter.MessageConverter in project spring-integration by spring-projects.

the class AmqpOutboundEndpoint method sendAndReceive.

private AbstractIntegrationMessageBuilder<?> sendAndReceive(String exchangeName, String routingKey, Message<?> requestMessage, CorrelationData correlationData) {
    Assert.isInstanceOf(RabbitTemplate.class, this.amqpTemplate, "RabbitTemplate implementation is required for publisher confirms");
    MessageConverter converter = ((RabbitTemplate) this.amqpTemplate).getMessageConverter();
    org.springframework.amqp.core.Message amqpMessage = MappingUtils.mapMessage(requestMessage, converter, getHeaderMapper(), getDefaultDeliveryMode(), isHeadersMappedLast());

        return null;
    }
    return buildReply(converter, amqpReplyMessage);
}

Example 4 with MessageConverter

use of org.springframework.amqp.support.converter.MessageConverter in project spring-integration by spring-projects.

the class AmqpOutboundEndpoint method returnedMessage.

@Override
public void returnedMessage(org.springframework.amqp.core.Message message, int replyCode, String replyText, String exchange, String routingKey) {
    // safe to cast; we asserted we have a RabbitTemplate in doInit()
    MessageConverter converter = ((RabbitTemplate) this.amqpTemplate).getMessageConverter();
    Message<?> returned = buildReturnedMessage(message, replyCode, replyText, exchange, routingKey, converter);
    getReturnChannel().send(returned);
