6、完整的匹配。如果一个队列绑定到该交换机上要求路由键 “test”，则只有被标记为“test”的消息才被转发，不会转发test.aaa，也不会转发dog.123，只会转发test。创建队列和交换机package com.neo.config;import org.springframework.amqp.core.DirectExchange;import org.springframework.amqp.core.Exchange;import org.springframework.amqp.core.Queue;import org.springframework.context.anno
