我正在尝试从kafka接收消息并用java方法处理它们。我附上的文件，可以帮助您了解和定位的问题。问题是我得到了错误：org.springframework.beans.factory.beancreationexception:创建名为“org.springframework.integration.config.consumerdpointfactorybean”的bean时出错，如下所示。

这个错误看起来很明显-你应该一直向下查看堆栈跟踪以找出原因。。。
原因：java.lang.illegalargumentexception:尚未为终结点“org.springframework.integration.config.consumerendpointfactorybean#0”定义轮询器，并且上下文中没有可用的默认轮询器。
自 inputFromKafka 是一个 QueueChannel ，您需要对其消费者进行民意调查。

<int:outbound-channel-adapter channel="inputFromKafka"... >
    <int:poller ... />
</int:outbound-channel-adapter>

但是，使用 QueueChannel 在这里是不必要的；只需移除 <int:queue/> 元素，你就不需要轮询器了。
