@ManagedResource @IntegrationManagedResource public class ZeroMqMessageProducer extends MessageProducerSupport
A MessageProducerSupport implementation for consuming messages from ZeroMq socket. Only SocketType.PAIR, SocketType.SUB and SocketType.PULL are supported. This component can bind or connect the socket.

When the SocketType.SUB is used, the received topic is stored in the ZeroMqHeaders.TOPIC.

    • setConsumeDelay

      public void setConsumeDelay(Duration consumeDelay)
      Specify a Duration to delay consumption when no data received.
      Parameters:
      consumeDelay - the Duration to delay consumption when empty; defaults to DEFAULT_CONSUME_DELAY.

    • setMessageMapper

      public void setMessageMapper(InboundMessageMapper<byte[]> messageMapper)
      Provide an InboundMessageMapper to convert a consumed data into a message to produce. Ignored when setReceiveRaw(boolean) is true.
      Parameters:
      messageMapper - the InboundMessageMapper to use.

    • setMessageConverter

      public void setMessageConverter(MessageConverter messageConverter)
      Provide a MessageConverter (as an alternative to messageMapper) for converting a consumed data into a message to produce. Ignored when setReceiveRaw(boolean) is true.
      Parameters:
      messageConverter - the MessageConverter to use.

    • setReceiveRaw

      public void setReceiveRaw(boolean receiveRaw)
      Whether raw ZMsg is present as a payload of message to produce or it is fully converted to a Message including ZeroMqHeaders.TOPIC header (if any).
      Parameters:
      receiveRaw - to convert from ZMsg or not; defaults to convert.

    • setSocketConfigurer

      public void setSocketConfigurer(Consumer<org.zeromq.ZMQ.Socket> socketConfigurer)
      Provide a Consumer to configure a socket with arbitrary options, like security.
      Parameters:
      socketConfigurer - the configurer for socket options.

    • setTopics

      public void setTopics(String... topics)
      Specify topics the SocketType.SUB socket is going to use for subscription. It is ignored for all other SocketTypes supported.
      Parameters:
      topics - the topics to use.

    • setConnectUrl

      public void setConnectUrl(@Nullable String connectUrl)
      Configure an URL for ZMQ.Socket.connect(String). Mutually exclusive with the setBindPort(int).
      Parameters:
      connectUrl - the URL to connect ZeroMq socket to.

    • setBindPort

      public void setBindPort(int port)
      Configure a port for TCP protocol binding via ZMQ.Socket.bind(String). Mutually exclusive with the setConnectUrl(String).
      Parameters:
      port - the port to bind ZeroMq socket to over TCP.

    • getBoundPort

      public int getBoundPort()
      Return the port a socket is bound or 0 if this message producer has not been started yet or the socket is connected - not bound.
      Returns:
      the port for a socket or 0.
