Annotation Interface EnableMessageLogReceiverEndpoint

@Target(TYPE) @Retention(RUNTIME) @Documented @Import({MessageLogReceiverEndpointBeanRegistrar.class,MessageLogReceiverEndpointAutoConfiguration.class}) @Repeatable(EnableMessageLogReceiverEndpoints.class) public @interface EnableMessageLogReceiverEndpoint

  • Element Details

    • channelName

      String channelName
      The name of the message-log channel.

      Resolving placeholders like "${my.channel.name}" is supported for this property.

      Returns:
      channel name

    • name

      String name
      The name of the registered MessageLogReceiverEndpoint bean.

      If #name is not set, the name of the bean is derived from the name of the message channel. The name is constructed by tranforming hyphenated variable naming convention, e.g., "my-channel" into the Spring bean naming convention, e.g., "myChannel". After this conversion, the string "MessageLogReceiverEndpoint" is appended. A channel named "my-channel" will therefore result in a bean name "myChannelMessageLogReceiverEndpoint".

      Returns:
      bean name
      Default:
      ""

    • startFrom

      String startFrom
      Specifies where to start reading from the message log.

      Possible Values:

      • HORIZON (default): Start reading from the oldest available message
      • LATEST: Start reading from the latest message
      Returns:
      LATEST or HORIZON
      Default:
      "HORIZON"

    • selector

      Class<? extends MessageLog> selector
      Selector used to select one of possibly multiple available MessageLogReceiverEndpointFactory instances used to create the MessageLogReceiverEndpoint.

      Example: the KafkaMessageLogReceiverEndpointFactory matches both MessageLog.class and Kafka.class. The following usage of the annotation is selecting the KafkaMessageLogReceiverEndpointFactory using the more specific Kafka selector: 

      
 @Configuration
 @EnableMessageLogReceiverEndpoint(
      channelName = "some-log",
      selector = Kafka.class)
 class MyExampleConfiguration {
 }
      Returns:
      MessageLog selector class
      Default:
      de.otto.synapse.channel.selector.MessageLog.class
