Examples with KafkaHandler org.springframework.kafka.annotation.KafkaHandler used on opensource projects

Example 1 with KafkaHandler

use of org.springframework.kafka.annotation.KafkaHandler in project open-kilda by telstra.

the class Gate method listen.

@KafkaHandler
void listen(@Payload ListIslPortsOnSwitch data) {
    Builder builder = CommandPacket.newBuilder();
    builder.setType(Type.LIST_ISLS);
    IslRttControl.ListIslsFilter listIslsFilter = IslRttControl.ListIslsFilter.newBuilder().setSwitchId(data.getSwitchId().toString()).build();
    builder.addCommand(Any.pack(listIslsFilter));
    try {
        CommandPacketResponse serverResponse = zeroMqClient.send(builder.build());
        if (serverResponse == null) {
            log.error("No response from server on {}", data.getHeaders().getCorrelationId());
