Spring Integration + Amazon SQS队列的工作示例

Question

我正在寻找一个Spring应用程序的工作示例，该应用程序使用Spring Integration + Amazon SQS服务接收消息并将消息发送到队列。

这是一个如何使用XML配置outbound channel adapter的示例：

 <int-aws:sqs-outbound-channel-adapter sqs="sqs"
                                      auto-startup="false"
                                      channel="errorChannel"
                                      phase="100"
                                      id="sqsOutboundChannelAdapter"
                                      queue="foo"
                                      delay-expression="'200'"
                                      message-deduplication-id="foo"
                                      message-group-id-expression="'bar'"
                                      send-timeout="202"
                                      sync="false"
                                      error-message-strategy="errorMessageStrategy"
                                      failure-channel="failureChannel"
                                      success-channel="successChannel"
                                      message-converter="messageConverter"
                                      async-handler="asyncHandler"
                                      resource-id-resolver="resourceIdResolver"/>

inbound channel adapter看起来像这样：

<int-aws:sqs-message-driven-channel-adapter sqs="sqs"
                                      auto-startup="false"
                                      channel="errorChannel"
                                      error-channel="nullChannel"
                                      task-executor="taskExecutor"
                                      phase="100"
                                      id="sqsMessageDrivenChannelAdapter"
                                      queues="foo, bar"
                                      message-deletion-policy="NEVER"
                                      max-number-of-messages="5"
                                      visibility-timeout="200"
                                      wait-time-out="40"
                                      send-timeout="2000"
                                      queue-stop-timeout="11000"
                                      destination-resolver="destinationResolver"
                                      resource-id-resolver="resourceIdResolver"/>

这里有Java变体：

    @Bean
    @ServiceActivator(inputChannel = "sqsSendChannelWithAutoCreate")
    public MessageHandler sqsMessageHandlerWithAutoQueueCreate() {
        DynamicQueueUrlDestinationResolver destinationResolver = new DynamicQueueUrlDestinationResolver(amazonSqs(), null);
        destinationResolver.setAutoCreate(true);
        return new SqsMessageHandler(amazonSqs(), destinationResolver);
    }


    @Bean
    public MessageProducer sqsMessageDrivenChannelAdapter() {
        SqsMessageDrivenChannelAdapter adapter = new SqsMessageDrivenChannelAdapter(amazonSqs(), "testQueue");
        adapter.setOutputChannel(inputChannel());
        return adapter;
    }
