使用Java DSL进行Spring集成的动态TCP服务器

我试图通过读取包含连接细节的属性文件来创建TCP服务器和客户端。 我在下面的参考文档（9.20动态和运行时集成流程）的帮助下使用动态和运行时集成流程

代码在创建客户端时工作正常，但是当我使用相同代码中的更改创建服务器时，如下所示：

IntegrationFlow flow = f -> f .handle(Tcp.inboundAdapter(Tcp.netServer(2221) .serializer(TcpCodecs.crlf()) .deserializer(TcpCodecs.lengthHeader1()) .id("server"))) .transform(Transformers.objectToString()); IntegrationFlowRegistration theFlow = this.flowContext.registration(flow).register(); 

我收到以下错误：

 Caused by: java.lang.IllegalArgumentException: Found ambiguous parameter type [class java.lang.String] for method match: [public java.lang.Class org.springframework.integration.dsl.IntegrationComponentSpec.getObjectType(), public S org.springframework.integration.dsl.MessageProducerSpec.outputChannel(java.lang.String), public S org.springframework.integration.dsl.MessageProducerSpec.outputChannel(org.springframework.messaging.MessageChannel), public org.springframework.integration.ip.dsl.TcpInboundChannelAdapterSpec org.springframework.integration.ip.dsl.TcpInboundChannelAdapterSpec.taskScheduler(org.springframework.scheduling.TaskScheduler), public S org.springframework.integration.dsl.MessageProducerSpec.errorMessageStrategy(org.springframework.integration.support.ErrorMessageStrategy), public S org.springframework.integration.dsl.MessageProducerSpec.phase(int), public S org.springframework.integration.dsl.MessageProducerSpec.autoStartup(boolean), public S org.springframework.integration.dsl.MessageProducerSpec.sendTimeout(long)] at org.springframework.util.Assert.isNull(Assert.java:155) at org.springframework.integration.util.MessagingMethodInvokerHelper.findHandlerMethodsForTarget(MessagingMethodInvokerHelper.java:843) at org.springframework.integration.util.MessagingMethodInvokerHelper.(MessagingMethodInvokerHelper.java:362) at org.springframework.integration.util.MessagingMethodInvokerHelper.(MessagingMethodInvokerHelper.java:231) at org.springframework.integration.util.MessagingMethodInvokerHelper.(MessagingMethodInvokerHelper.java:225) at org.springframework.integration.handler.MethodInvokingMessageProcessor.(MethodInvokingMessageProcessor.java:60) at org.springframework.integration.handler.ServiceActivatingHandler.(ServiceActivatingHandler.java:38) at org.springframework.integration.dsl.IntegrationFlowDefinition.handle(IntegrationFlowDefinition.java:924) at org.springframework.integration.dsl.IntegrationFlowDefinition.handle(IntegrationFlowDefinition.java:904) at org.springframework.integration.dsl.IntegrationFlowDefinition.handle(IntegrationFlowDefinition.java:891) at org.springframework.integration.samples.dynamictcp.DynamicTcpClientApplication.lambda$1(DynamicTcpClientApplication.java:194) at org.springframework.integration.config.dsl.IntegrationFlowBeanPostProcessor.processIntegrationFlowImpl(IntegrationFlowBeanPostProcessor.java:268) at org.springframework.integration.config.dsl.IntegrationFlowBeanPostProcessor.postProcessBeforeInitialization(IntegrationFlowBeanPostProcessor.java:96) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsBeforeInitialization(AbstractAutowireCapableBeanFactory.java:423) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1702) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:583) ... 16 common frames omitted 

请帮助我解决上述问题。 我也找到了动态tcp客户端的代码，但动态tcp服务器没有代码（我可以创建动态服务器的任何资源或链接）。

你是混合责任。 Tcp.inboundAdapter()必须是IntegrationFlow链中的第一个。 考虑使用此代替：

 IntegrationFlow flow = IntegrationFlows.from(Tcp.inboundAdapter(Tcp.netServer(2221) .serializer(TcpCodecs.crlf()) .deserializer(TcpCodecs.lengthHeader1()) .id("server"))) .transform(Transformers.objectToString()) .get();
