Examples with MessageListener org.springframework.amqp.core.MessageListener used on opensource projects

Example 1 with MessageListener

use of org.springframework.amqp.core.MessageListener 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 2 with MessageListener

use of org.springframework.amqp.core.MessageListener in project spring-integration by spring-projects.

the class AbstractSubscribableAmqpChannel method onInit.

@Override

    this.dispatcher = this.createDispatcher();
    if (this.maxSubscribers == null) {
        this.maxSubscribers = this.getIntegrationProperty(this.isPubSub ? IntegrationProperties.CHANNELS_MAX_BROADCAST_SUBSCRIBERS : IntegrationProperties.CHANNELS_MAX_UNICAST_SUBSCRIBERS, Integer.class);
    }
    setMaxSubscribers(this.maxSubscribers);
    String queue = obtainQueueName(this.channelName);
    this.container.setQueueNames(queue);
    MessageConverter converter = (this.getAmqpTemplate() instanceof RabbitTemplate) ? ((RabbitTemplate) this.getAmqpTemplate()).getMessageConverter() : new SimpleMessageConverter();
    MessageListener listener = new DispatchingMessageListener(converter, this.dispatcher, this, this.isPubSub, getMessageBuilderFactory(), getInboundHeaderMapper());
    this.container.setMessageListener(listener);
    if (!this.container.isActive()) {
        this.container.afterPropertiesSet();
    }
}

Example 3 with MessageListener

use of org.springframework.amqp.core.MessageListener in project spring-integration by spring-projects.

the class DispatcherHasNoSubscribersTests method testPubSub.

@Test
public void testPubSub() {
    final Channel channel = mock(Channel.class);
    Connection connection = mock(Connection.class);
    doAnswer(invocation -> channel).when(connection).createChannel(anyBoolean());
    ConnectionFactory connectionFactory = mock(ConnectionFactory.class);
    when(connectionFactory.createConnection()).thenReturn(connection);
    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
    container.setConnectionFactory(connectionFactory);
    AmqpTemplate amqpTemplate = mock(AmqpTemplate.class);
    PublishSubscribeAmqpChannel amqpChannel = new PublishSubscribeAmqpChannel("noSubscribersChannel", container, amqpTemplate);
    amqpChannel.setBeanName("noSubscribersChannel");
    amqpChannel.setBeanFactory(mock(BeanFactory.class));
    amqpChannel.afterPropertiesSet();
    List<String> logList = insertMockLoggerInListener(amqpChannel);
    MessageListener listener = (MessageListener) container.getMessageListener();
    listener.onMessage(new Message("Hello world!".getBytes(), null));
    verifyLogReceived(logList);
}
