RabbitMQ的核心概念包括producers(发送消息)、exchanges(路由消息)、queues(保存消息)、bindings(连接exchanges和queues的规则)和consumers(接收消息)。理解消息如何流经它们是基础。
核心组件
text
PRODUCER → sends messages (to an EXCHANGE, not directly to a queue)
EXCHANGE → receives messages and ROUTES them to queues (based on rules/type)
QUEUE → holds messages until consumed (a buffer; FIFO-ish)
BINDING → a rule linking an exchange to a queue (how/when to route there)
CONSUMER → receives and processes messages from a queue
→ producer → exchange → (binding rules) → queue(s) → consumer
