SpringBoot 集成RabbitMQ

spring:
rabbitmq:
  host: localhost
  port: 5672
  listener:
    simple:
      acknowledge-mode: manual // 手动签发
      prefetch: 1
      retry:
        enabled: true
        initial-interval: 60000 # 第一次和第二次尝试发布或传递消息间隔: 1分钟
        max-attempts: 8
        max-interval: 7200000 # 最大重试时间间隔：2小时
        multiplier: 2 # 应用于上一重试间隔的乘数
