我有一个简单的 Spring Integration 流,它绑定到处理器以进行输入和输出。

我已将 Kafka 活页夹配置为映射输入和输出主题。这完美无缺。

假设我想将 3 个 Kafka 主题绑定到输入,导致 3 个配置的消费者从三个单独的 kafka 主题中提取,然后由我的 SI 流处理。

是否可以将多个 Kafka 主题映射到我的处理器的输入?如果是这样,该配置的外观如何?

如果destination属性是逗号分隔的列表,将为每个目标创建一个侦听器容器并绑定到同一个侦听器。

您还可以将该multiplex属性设置为 true,这样我们就只有一个容器可以监听多个主题。

spring.cloud.stream.bindings.foo.consumer.multiplex=true.

/**
 * When set to true, the underlying binder will natively multiplex destinations on the
 * same input binding. For example, in the case of a comma separated multiple
 * destinations, the core framework will skip binding them individually if this is set
 * to true, but delegate that responsibility to the binder.
 *
 * By default this property is set to `false` and the binder will individually bind
 * each destinations in case of a comma separated multi destination list. The
 * individual binder implementations that need to support multiple input bindings
 * natively (multiplex) can enable this property.
 */
private boolean multiplex;

您必须设置多路复用属性才能启用它。
