简单实现一个mq确认消息不丢失的Java代码

以下是一个简单的mq确认消息不丢失的Java代码示例：

//创建连接工厂
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("localhost");

//创建连接
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();

//声明队列
String queueName = "myQueue";
channel.queueDeclare(queueName, false, false, false, null);

//设置消费者
Consumer consumer = new DefaultConsumer(channel) {
@Override
public void handleDelivery(String consumerTag, Envelope envelope,
AMQP.BasicProperties properties, byte[] body) throws IOException {
String message = new String(body, "UTF-8");
//确认消息
channel.basicAck(envelope.getDeliveryTag(), false);
}
};

//开始消费
channel.basicConsume(queueName, false, consumer);
