在 AmazonMQ 维护窗口期间，RabbitMQ自动消费者会出现连接中断的情况，可以通过以下两种方式进行解决：

1. 使用 RabbitMQ 的自动恢复机制。在 RabbitMQ 客户端连接断开后，自动恢复机制会尝试重连并重新启动消费者。可以通过设置 RecoveryInterval 参数控制自动恢复尝试的时间间隔。

示例代码：

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()

def callback(ch, method, properties, body):
    print("Received %r" % body)

channel.basic_consume(queue='hello', on_message_callback=callback, auto_ack=True)

try:
    channel.start_consuming()
except pika.exceptions.ConnectionClosed:
    print('Connection closed! Will try to reconnect in 5 seconds...')
    time.sleep(5)

2. 手动恢复消费者连接。如果自动恢复机制未能在 AmazonMQ 维护窗口期间成功重连，可以通过手动重连方式来恢复消费者连接。

示例代码：

import pika

# connect to RabbitMQ
connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()

# create consumer
def callback(ch, method, properties, body):
    print("Received %r" % body)

channel.basic_consume(queue='hello', on_message_callback=callback, auto_ack=True)

while True:
    try:
        channel.start_consuming()
    except pika.exceptions.ConnectionClosed:
        print('Disconnected! Attempting to reconnect...')
        try:
            connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
            channel = connection.channel()
            channel.basic_consume(queue='hello', on_message_callback=callback, auto_ack=True)
        except Exception as e:
            print('Could not reconnect:', str(e))
