Multiplex
从版本 4.0.3 开始，反应式绑定程序现在支持通用消费者属性 multiplex，其中单个绑定可以从多个主题使用。当 false（默认值），将为通用 destination 属性中以逗号分隔的列表中指定的每个主题创建一个单独的绑定。
Starting with version 4.0.3, the common consumer property multiplex is now supported by the reactive binder, where a single binding can consume from multiple topics.
When false (default), a separate binding is created for each topic specified in a comma-delimited list in the common destination property.
