问题 When I consume the message from kinesis stream. I get some junk chars with headers etc @StreamListener(Processor.INPUT) public void receive(String message) { System.out.println("Message recieved: "+message); throw new RuntimeException("Exception thrown"); } @StreamListener("errorChannel") public void transform(ErrorMessage errorMessage) throws UnsupportedEncodingException { //original paylaod System.out.println("Error Oiginal Message Payload"+new String((byte[])errorMessage.getOriginalMessage

问题 have a spring boot application, where I am trying to place a file into multiple S3 bucket using single S3 outbound adapter.. Would like to know if its possible to place the file in multiple bucket using single outbound adapter using spring-integration-aws itself( without using aws -sdk) Any suggestion will be helpful.

问题 I am trying to consume messages from Kinesis stream as batch I am using compile('org.springframework.cloud:spring-cloud-starter-stream-kinesis:1.0.0.BUILD-SNAPSHOT') Application.yml spring: cloud: stream: bindings: input: group: groupName destination: stream-name content-type: application/json consumer: listenerMode: batch idleBetweenPolls: 10000 Code As per the documentation, when listenerMode is batch, then it is expected to have list as payload @StreamListener(Sink.INPUT) public void

问题 I've a requirement to download a file from S3 based on a message content. In other words, the file to download is previously unknown, I've to search and find it at runtime. S3StreamingMessageSource doesn't seem to be a good fit because: It relies on polling where as I need to wait for the message. I can't find any way to create a S3StreamingMessageSource dynamically in the middle of a flow. gateway(IntegrationFlow) looks interesting but what I need is a gateway(Function<Message<?>,

问题 I am working on a backend service which polls S3 bucket periodically using spring aws integration and processes the polled object from S3. Below is the implementation for it @Configuration @EnableIntegration @IntegrationComponentScan @EnableAsync public class S3PollerConfiguration { //private static final Logger log = (Logger) LoggerFactory.getLogger(S3PollerConfiguration.class); @Value("${amazonProperties.bucketName}") private String bucketName; @Bean @InboundChannelAdapter(value =

问题 I am consuming messages in batch mode. I wanted to pull 8 messages each 250 ms from stream. spring: cloud: stream: kinesis: bindings: input: consumer: listenerMode: batch idleBetweenPolls: 250 recordsLimit: 8 bindings: input: group: my-group destination: stream content-type: application/json I have pushed around 100 messages on to stream, and I started the consumer. As per configuration, I am supposed to pull messages each 250 ms. But the poller not pulling messages each 250 ms.

问题 I've the following flow: @Resource(name = S3_CLIENT_BEAN) private MessageSource<InputStream> messageSource; public IntegrationFlow fileStreamingFlow() { return IntegrationFlows.from(s3Properties.getFileStreamingInputChannel()) .enrichHeaders(spec -> spec.header(ERROR_CHANNEL, S3_ERROR_CHANNEL, true)) .handle(String.class, (fileName, h) -> { if (messageSource instanceof S3StreamingMessageSource) { S3StreamingMessageSource s3StreamingMessageSource = (S3StreamingMessageSource) messageSource;
