问题

rabbitmq消费手动确认时rabbitmq日志报 unknown delivery tag 1，代码日志报
Channel shutdown: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - unknown delivery tag 1, class-id=60, method-id=80)

spring: 
  rabbitmq:
    host: 192.168.5.100
    port: 5672
    username: guest
    password: guest

以上是我的配置文件。

原因

原因是因为进行了两次消息确认double ack.，配置手动签收模式失效，被注解注入的SimpleRabbitListenerContainerFactory覆盖，而它默认使用了自动签收。

解决

配置类

    @Bean
    public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory(ConnectionFactory connectionFactory, MessageConverter messageConverter) {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        factory.setMessageConverter(messageConverter);
        factory.setAcknowledgeMode(AcknowledgeMode.MANUAL);
        return factory;
    }

 spring:
  rabbitmq:
    host: 192.168.5.188
    port: 5672
    username: guest
    password: guest
    listener:
      direct:
        acknowledge-mode: manual # 消费端手动ack消息
