Too many messages are sent to the topic in Cloud PubSub [Spring Boot]

问题

我正在使用GCP和Cloud PubSub开发一个聊天服务器。

我想要从一个使用Spring Integration的实例向Cloud PubSub中的主题发送消息，但它发送了太多消息。

这是实例的代码。

创建一个入站通道适配器以侦听订阅chat-sub并将消息发送到输入消息通道。

@Bean
fun inboundChannelAdapter(
    @Qualifier("inputMessageChannel") messageChannel: MessageChannel?,
    pubSubTemplate: PubSubTemplate?
): PubSubInboundChannelAdapter? {
    val adapter = PubSubInboundChannelAdapter(pubSubTemplate, "chat-sub")
    adapter.outputChannel = messageChannel
    adapter.ackMode = AckMode.AUTO
    adapter.payloadType = String::class.java
    return adapter
}

定义消息到达消息通道时发生的操作。

@ServiceActivator(inputChannel = "inputMessageChannel")
fun messageReceiver(
    payload: String,
    @Header(GcpPubSubHeaders.ORIGINAL_MESSAGE) message: BasicAcknowledgeablePubsubMessage
) {
    val model = gson.fromJson(payload, ChatMessageToPubSub::class.java)
    
    messagingTemplate.convertAndSend("/sub/message/" + model.roomId.toString(), ChatMessageToClient(model.userId, model.message))
    message.ack()
}

创建一个出站通道适配器，将输入消息通道中的消息发送到主题chat。

@Bean
@ServiceActivator(inputChannel = "inputMessageChannel")
fun messageSender(pubsubTemplate: PubSubTemplate?): MessageHandler? {
    val adapter = PubSubMessageHandler(pubsubTemplate, "chat")
    adapter.setSuccessCallback { ackId, message -> println("send success : " + message.payload) }
    adapter.setFailureCallback { cause, message -> println("send fail : " + message.payload) }
    return adapter
}

MessagingGateway接口用于向Pubsub发送消息。

@MessagingGateway(defaultRequestChannel = "inputMessageChannel")
interface PubSubOutBoundGateway {
    @Throws(MessagingException::class)
    fun sendToPubsub(text: String)
}

当我关闭实例时，我在客户端收到了大约200条消息。

第一个错误是：

org.springframework.messaging.MessageHandlingException: Missing header 'gcp_pubsub_original_message' for method parameter type [interface com.google.cloud.spring.pubsub.support.BasicAcknowledgeablePubsubMessage]

我认为这是消息重发的关键，所以我尝试添加了GcpPubSubHeaders.ORIGINAL_MESSAGE头。但我找不到实现BasicAcknowledgeablePubsubMessage的类来生成对象。

我现在漏掉了什么？

或者是否有停止重试的方法当发生异常时？

I'm using GCP and Cloud PubSub to develop a chatting server now.

I wanted to send a message to the topic in Cloud PubSub from an instance using Spring Integration, but it sent too many messages.

DEFAULT 2023-06-14T18:53:54.237158Z send fail : {"roomId":1,"userId":1,"message":"zxcv"}

This is the code of the instance.

    // Create an inbound channel adapter to listen to the subscription `chat-sub` and send
// messages to the input message channel.
@Bean
fun inboundChannelAdapter(
@Qualifier("inputMessageChannel") messageChannel: MessageChannel?,
pubSubTemplate: PubSubTemplate?
): PubSubInboundChannelAdapter? {
val adapter = PubSubInboundChannelAdapter(pubSubTemplate, "chat-sub")
adapter.outputChannel = messageChannel
adapter.ackMode = AckMode.AUTO
adapter.payloadType = String::class.java
return adapter
}
// Define what happens to the messages arriving in the message channel.
@ServiceActivator(inputChannel = "inputMessageChannel")
fun messageReceiver(
payload: String,
@Header(GcpPubSubHeaders.ORIGINAL_MESSAGE) message: BasicAcknowledgeablePubsubMessage
) {
val model = gson.fromJson(payload, ChatMessageToPubSub::class.java)
messagingTemplate.convertAndSend("/sub/message/" + model.roomId.toString(), ChatMessageToClient(model.userId, model.message))
message.ack()
//LOGGER.info("Message arrived via an inbound channel adapter from chat-sub! Payload: $payload")
}
// Create an outbound channel adapter to send messages from the input message channel to the
// topic `chat`.
@Bean
@ServiceActivator(inputChannel = "inputMessageChannel")
fun messageSender(pubsubTemplate: PubSubTemplate?): MessageHandler? {
val adapter = PubSubMessageHandler(pubsubTemplate, "chat")
adapter.setSuccessCallback { ackId, message -> println("send success : " + message.payload) }
adapter.setFailureCallback { cause, message -> println("send fail : " + message.payload) }
return adapter
}

@MessagingGateway(defaultRequestChannel = "inputMessageChannel")
interface PubSubOutBoundGateway {
@kotlin.jvm.Throws(MessagingException::class)
fun sendToPubsub(text : String)
}

So I received about 200 messages at my client side by shutting down the instance.

The first error is

org.springframework.messaging.MessageHandlingException: Missing header 'gcp_pubsub_original_message' for method parameter type [interface com.google.cloud.spring.pubsub.support.BasicAcknowledgeablePubsubMessage]

I thought it is the key of the message resending, so I tried to add GcpPubSubHeaders.ORIGINAL_MESSAGE header.
But I could not find the class that implements BasicAcknowledgeablePubsubMessage to generate the object.

What am I missing now?

Or is there any way stopping retrying when exception occurs?

得分: 1

这是翻译后的部分：

"因为发送到主题的消息会返回到 inputMessageChannel，所以 messageSender 适配器再次工作。

因此，我将入站通道和出站通道分开，所以代码看起来像这样。

@Bean
fun inputMessageChannel(): MessageChannel? {
    return PublishSubscribeChannel()
}

@Bean
fun outputMessageChannel(): MessageChannel? {
    return PublishSubscribeChannel()
}

// 创建入站通道适配器以侦听订阅 `chat-sub` 并将消息发送到输入消息通道。
@Bean
fun inboundChannelAdapter(
    @Qualifier("inputMessageChannel") messageChannel: MessageChannel?,
    pubSubTemplate: PubSubTemplate?
): PubSubInboundChannelAdapter? {
    val adapter = PubSubInboundChannelAdapter(pubSubTemplate, "chat-sub")
    adapter.outputChannel = messageChannel
    adapter.ackMode = AckMode.MANUAL
    adapter.payloadType = String::class.java
    return adapter
}

// 定义消息到达消息通道时发生的操作。
@ServiceActivator(inputChannel = "inputMessageChannel")
fun messageReceiver(
    payload: String,
    @Header(GcpPubSubHeaders.ORIGINAL_MESSAGE) message: BasicAcknowledgeablePubsubMessage
) {
    val model = gson.fromJson(payload, ChatMessageToPubSub::class.java)
    println("received message : " + message.pubsubMessage.data.toStringUtf8())
    println(message.pubsubMessage.attributesMap)
    message.ack()
    messagingTemplate.convertAndSend("/sub/message/" + model.roomId.toString(), ChatMessageToClient(model.userId, model.message))
    //LOGGER.info("Message arrived via an inbound channel adapter from chat-sub! Payload: $payload")
}

// 创建出站通道适配器，将消息从输入消息通道发送到主题 `chat`。
@Bean
@ServiceActivator(inputChannel = "outputMessageChannel")
fun messageSender(pubsubTemplate: PubSubTemplate?): MessageHandler? {
    val adapter = PubSubMessageHandler(pubsubTemplate, "chat")
    adapter.setSuccessCallback { ackId, message -> println("send success : " + ackId + " - " + message.payload) }
    adapter.setFailureCallback { cause, message -> println("send fail : " + cause.stackTraceToString() + " - " + message.payload) }
    adapter.setPublishTimeoutExpressionString("500")
    return adapter
}

@MessagingGateway(defaultRequestTimeout = "500", defaultRequestChannel = "outputMessageChannel", errorChannel = "errorChannel")
interface PubSubOutBoundGateway {
    @kotlin.jvm.Throws(MessagingException::class, MessageHandlingException::class)
    fun sendToPubsub(text: String)
}

然后它就能正常工作。"

英文:

It is because the message sent to the topic goes back to inputMessageChannel, so messageSender adapter works again.

So I separate inbound channel and outbound channel, so the code looks like this.

    @Bean
fun inputMessageChannel(): MessageChannel? {
return PublishSubscribeChannel()
}
@Bean
fun outputMessageChannel(): MessageChannel? {
return PublishSubscribeChannel()
}
// Create an inbound channel adapter to listen to the subscription `chat-sub` and send
// messages to the input message channel.
@Bean
fun inboundChannelAdapter(
@Qualifier("inputMessageChannel") messageChannel: MessageChannel?,
pubSubTemplate: PubSubTemplate?
): PubSubInboundChannelAdapter? {
val adapter = PubSubInboundChannelAdapter(pubSubTemplate, "chat-sub")
adapter.outputChannel = messageChannel
adapter.ackMode = AckMode.MANUAL
adapter.payloadType = String::class.java
return adapter
}
// Define what happens to the messages arriving in the message channel.
@ServiceActivator(inputChannel = "inputMessageChannel")
fun messageReceiver(
payload: String,
@Header(GcpPubSubHeaders.ORIGINAL_MESSAGE) message: BasicAcknowledgeablePubsubMessage
) {
val model = gson.fromJson(payload, ChatMessageToPubSub::class.java)
println("received message : " + message.pubsubMessage.data.toStringUtf8())
println(message.pubsubMessage.attributesMap)
message.ack()
messagingTemplate.convertAndSend("/sub/message/" + model.roomId.toString(), ChatMessageToClient(model.userId, model.message))
//LOGGER.info("Message arrived via an inbound channel adapter from chat-sub! Payload: $payload")
}
// Create an outbound channel adapter to send messages from the input message channel to the
// topic `chat`.
@Bean
@ServiceActivator(inputChannel = "outputMessageChannel")
fun messageSender(pubsubTemplate: PubSubTemplate?): MessageHandler? {
val adapter = PubSubMessageHandler(pubsubTemplate, "chat")
adapter.setSuccessCallback { ackId, message -> println("send success : " + ackId + " - " + message.payload) }
adapter.setFailureCallback { cause, message -> println("send fail : " + cause.stackTraceToString() + " - " + message.payload) }
adapter.setPublishTimeoutExpressionString("500")
return adapter
}

@MessagingGateway(defaultRequestTimeout = "500", defaultRequestChannel = "outputMessageChannel", errorChannel = "errorChannel")
interface PubSubOutBoundGateway {
@kotlin.jvm.Throws(MessagingException::class, MessageHandlingException::class)
fun sendToPubsub(text : String)
}

Then it works.
