Spring integration 升级到Spring Framework 4.2.4后，Spring集成Java配置突然失败

我将Spring框架从4.1.4升级到4.2.4。我们的Spring集成版本是4.2.0，但问题也会出现在SI 4.2.4上

升级到SF 4.2.2后，我们收到以下运行时错误：

org.springframework.messaging.MessageDeliveryException: Dispatcher has no subscribers for channel 'org.springframework.context.annotation.AnnotationConfigApplicationContext@41799345.inboundRouting.inputChannel'.; nested exception is org.springframework.integration.MessageDispatchingException: Dispatcher has no subscribers

当我检查日志时，我没有看到transformer:inboundRoutingConfig.assignPriority.transformer被添加为inboundRouting.inputChannel的订户。这解释了“Dispatcher没有订户”。但是，如果我回到SF 4.1.4，我会看到变压器作为用户添加到通道中，并且运行良好

你知道为什么Spring框架升级会导致这个问题吗

这是特定的配置，失败的部分是

assignPriority

@Transformer注释方法

请注意，

@EnableConfiguration

位于项目中另一个

@Configuration

注释类上，但我也尝试将其添加到此类中

对不起，你的配置不是那么简单，从我这边播放。我看到问题来自AMQP入站通道适配器，看起来您在应用程序之前的队列中有消息。在启动应用程序之前，我在

foo

队列中有类似的配置和消息

@Configuration
@EnableIntegration
public static class MyConfig {

    @Transformer(inputChannel = "input", outputChannel = "nullChannel")
    public String transform(String payload) throws Exception {
        System.out.println(payload);
        return payload;
    }

    @Bean
    public MessageChannel input() {
        return new DirectChannel();
    }

    @Bean
    public CachingConnectionFactory connectionFactory() {
        return new CachingConnectionFactory("localhost", AMQP.PROTOCOL.PORT);
    }

    @Bean
    public SimpleMessageListenerContainer container() {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(connectionFactory());
        container.setQueueNames("foo");
        return container;
    }

    @Bean
    public AmqpInboundChannelAdapter amqpInboundChannelAdapter() {
        AmqpInboundChannelAdapter channelAdapter = new AmqpInboundChannelAdapter(container());
        channelAdapter.setOutputChannel(input());
        return channelAdapter;
    }

}

一切都很顺利。AMQP入站通道适配器在

@Transformer

端点之后启动，因此最后一个适配器能够在队列侦听后拾取第一个适配器生成的消息

在异常发生之前，您是否介意共享

org.springframework

类别的调试？

请确认您在某处有

4.2.x

分支完全基于

SF-4.2.x

，我们还没有遇到类似的问题。我确实在其他地方有

@enableingration

，但在这里尝试过，但没有成功。我已经更新了堆栈跟踪的问题，并将为您进行最小化配置。太好了！非常感谢。我想查看您的

springIntegrationConfigHelper.createInboundChannelAdapter（）

。我想知道您是否对那里的

阶段做了什么…我添加了
createInboundChannelAdapter（）
代码以及一个独立的配置和测试消息类，该类复制了问题。请共享应用程序启动后的整个日志。我想看看Spring是如何加载的，请确认您在某处有

publicstaticvoidmain（String[]args）{AnnotationConfigApplicationContext=ApplicationContextListener.getSpringContext（）；context.registerSuttonhook（）；context.refresh（）；context.start（）；}
。然而，你的提问很有趣。我作为应用程序在本地运行，以简化测试设置。在生产环境中，它在Tomcat7实例中运行，在web.xml中有一个简单的侦听器：
com.mimedia.index.config.ApplicationContextListener
。我的问题一直作为java应用程序运行。什么是
ApplicationContextListener
？在Spring中似乎没有这样的类。我查看了一下，它使用的是
AnnotationConfigApplicationContext
。这可能是问题的根源：有一些条件区域
