升级到Spring Integration 5后,使用消息不再有效

问题描述 投票:0回答:1

我正在尝试使用Spring Integration 4.3和Spring Boot 1.6将项目升级到Spring Integration 5.1和Spring Boot 2.1。以前我有以下配置:

IntegrationFlows.from(Amqp.inboundAdapter(connectionFactory, "queueName")
                    .id("myId")
                    .autoStartup(autoStartup)
                    .prefetchCount(10)
                    .concurrentConsumers(2)
                    .maxConcurrentConsumers(3)
                    .messageConverter(messageConverter()))
                    .aggregate(a -> a.correlationExpression("payload.entityId")
                                    .releaseExpression("size() eq iterator().next().payload.batchSize")
                                    .sendPartialResultOnExpiry(true)
                                    .groupTimeout(2000)
                                    .expireGroupsUponCompletion(true)
                                    .outputProcessor(myMessageGroupProcessor))
                    .handle(serviceActivatorBean, "myMethod", e -> e.advice(requestHandlerRetryAdviceForIntegrationFlow()))
                    .get();

在升级过程中,我试图遵循文档here,从而将配置更改为:

@Configuration
@EnableAutoConfiguration
@EnableIntegration
public class SpringConfig {

    @Bean(name = "myFlowId")
    public IntegrationFlow myFlow(ConnectionFactory connectionFactory, ServiceActivatorBean serviceActivatorBean,
                                  @Value("${spring.integration.flow.auto-startup:true}") boolean autoStartup,
                                  MyMessageGroupProcessor myMessageGroupProcessor) {
        IntegrationFlows.from(Amqp.inboundAdapter(connectionFactory, "queueName")
                        .id("myId")
                        .autoStartup(autoStartup)
                        .configureContainer(c -> c.acknowledgeMode(MANUAL)
                            .prefetchCount(10)
                            .concurrentConsumers(2)
                            .maxConcurrentConsumers(3)
                        )
                        .messageConverter(messageConverter()))
                        .aggregate(a -> a.correlationExpression("payload.entityId")
                                        .releaseExpression("size() eq one().payload.batchSize")
                                        .sendPartialResultOnExpiry(true)
                                        .groupTimeout(2000)
                                        .expireGroupsUponCompletion(true)
                                        .outputProcessor(myMessageGroupProcessor))
                        .handle(serviceActivatorBean, "myMethod", e -> e.advice(requestHandlerRetryAdviceForIntegrationFlow()))
                        .get();
    }
}

但是当我发布消息时,它们似乎并不是由集成流接收/处理的。即使我启用调试日志记录,我也没有得到任何错误日志(或任何日志),我不确定从哪里开始调试。我很肯定这些消息实际发布到RabbitMQ,所以这不是问题所在。我能错过什么?

我的问题实际上不是由于Spring Integration,而是与Spring AMQP的变化有关。以前“声明”可以像这样创建:

@Bean
List<Binding> myBinding() {
    return List.of(<binding1>, <binding2>, ..)
}

但在Spring AMQP 2.1中,这应该改为:

@Bean
Declarables myBinding() {
    return new Declarables(List.of(<binding1>, <binding2>, ..))
}

请参阅文档here

顺便说一句,我的releaseExpression也错了,它应该是size() eq one.payload.batchSize
