spring-integration - 使用客户端 ConnectionFactory 停止 TCP 适配器

问题描述

我正在尝试使用控制总线命令停止带有客户端连接工厂的 TCP 适配器，即@AdapterID.stop() 创建流的代码如下：

 IntegrationFlow flow = IntegrationFlows.from(Tcp.inboundAdapter(Tcp.nioClient("127.0.0.1",3226))
             .serializer(customSerializer)
             .deserializer(customSerializer)
             .id("abc")).clientMode(true).retryInterval(1000).errorChannel("testChannel"))
             .enrichHeaders(f->f.header("abc","abc"))
             .channel(directChannel())
             .handle(Jms.outboundAdapter(ConnectionFactory())
             .destination(hostConnection.getConnectionNumber()))
             .get();

     theFlow = this.flowContext.registration(flow).id("out.flow").register();

当我使用控制总线停止适配器时：

 public String stopConnectionAdapter(String connectionName) {
    MessageChannel controlChannel = ac.getBean("controlBus.input", MessageChannel.class); 
    String exp = "@"+connectionName+".stop()";
    controlChannel.send(new GenericMessage<String>(exp));
    return "STOPPED";
}

适配器已停止，但控制台上始终会打印以下异常

如何停止此错误并关闭连接而不会出现任何异常和错误。

另外，以预期方式顺序处理（在运行时启动和停止）这些连接（集成流组件）而没有任何错误的有效方法是什么？

解决方案

你不应该停止工厂；它的生命周期由适配器控制；只需停止适配器；无需停止其他组件。

您也可以stop()使用整个IntegrationFlowbean ( out.flow)，它会停止组件。
