在springcloudstreamdataflow和rabbitmq中,消费者组的正确用法是什么?

后续行动:

one SCDF source, 2 processors but only 1 processes each item

我的处理器有以下功能应用程序.属性

spring.application.name=${vcap.application.name:sample-processor}
info.app.name=@project.artifactId@
info.app.description=@project.description@
info.app.version=@project.version@
management.endpoints.web.exposure.include=health,info,bindings
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration
spring.cloud.stream.bindings.input.group=input

是“云。溪流.bindings.input.group“正确指定?

以下是处理器代码:

@Transformer(inputChannel = Processor.INPUT, outputChannel = Processor.OUTPUT)
public Object transform(String inputStr) throws InterruptedException{

    ApplicationLog log = new ApplicationLog(this, "timerMessageSource");

    String message = " I AM [" + inputStr + "] AND I HAVE BEEN PROCESSED!!!!!!!";

    log.info("SampleProcessor.transform() incoming inputStr="+inputStr);

    return message;
}

@Transformer注释是将这段代码与云。溪流.bindings.input.group“从应用程序属性?是否需要其他注释?

以下是我的消息来源:

private String format = "EEEEE dd MMMMM yyyy HH:mm:ss.SSSZ";
@Bean
@InboundChannelAdapter(value = Source.OUTPUT, poller = @Poller(fixedDelay = "1000", maxMessagesPerPoll = "1"))
public MessageSource<String> timerMessageSource() {
    ApplicationLog log = new ApplicationLog(this, "timerMessageSource");
    String message = new SimpleDateFormat(format).format(new Date());
    log.info("SampleSource.timeMessageSource() message=["+message+"]");
    return () -> new GenericMessage<>(new SimpleDateFormat(format).format(new Date()));
}

加入@Poller会给我带来什么问题吗?

这是我如何在SCDF shell中定义2个处理器流(del-1和del-2):

stream create del-1 --definition ":split > processor-that-does-everything-sleeps5 --spring.cloud.stream.bindings.applicationMetrics.destination=metrics > :merge"

stream create del-2 --definition ":split > processor-that-does-everything-sleeps5 --spring.cloud.stream.bindings.applicationMetrics.destination=metrics > :merge"

我需要在那里做些什么不同的事情吗?

RabbitMQ由bitnami给出/rabbitmq:3.7.2-r1和配置了以下道具:

RABBITMQ_USERNAME: user
RABBITMQ_PASSWORD <redacted>:  
RABBITMQ_ERL_COOKIE <redacted>:  
RABBITMQ_NODE_PORT_NUMBER: 5672
RABBITMQ_NODE_TYPE: stats
RABBITMQ_NODE_NAME: rabbit@localhost
RABBITMQ_CLUSTER_NODE_NAME: 
RABBITMQ_DEFAULT_VHOST: /
RABBITMQ_MANAGER_PORT_NUMBER: 15672
RABBITMQ_DISK_FREE_LIMIT: "6GiB"

是否需要其他环境变量?
