SpringBoot RabbitMQTemplate消费者确认机制怎么选？

spring:
  rabbitmq:
    listener:
      simple:
        acknowledge-mode: 确认模式

spring:
  rabbitmq:
    listener:
      simple:
        retry:
          enabled: true # 开启消费者失败重试
          initial-interval: 1000ms # 初识的失败等待时长为1秒
          multiplier: 1 # 失败的等待时长倍数，下次等待时长 = multiplier * last-interval
          max-attempts: 3 # 最大重试次数
          stateless: true # true无状态；false有状态。如果业务中包含事务，这里改为false
