效果流程
生成者与消费者公用的pom.xml

测试启动文件

消费者创建

rabbitmq.username=guest
rabbitmq.password=guest

prefetch:表示签收数据量,可以起到限流作用

Consumer类
public class Consumerimplements ChannelAwareMessageListener {
@Override

//获取发送过来的标识
long deliveryTag = message.getMessageProperties().getDeliveryTag();
try {
//接收发送过来的数据
System.out.println(new String(message.getBody()));

//正常接收就自动确认
channel.basicAck(deliveryTag,true);
}catch (IOException e) {
e.printStackTrace();
//接收异常,回滚数据
//第一个参数是标识 第二个是是否确认拒绝签收 第三个是否回滚数据,重新发送(true),要是为false 数据就会抛弃
channel.basicNack(deliveryTag,true,true);
}
