增加监听器
channel.addConfirmListener(new ConfirmListener() {


/*
* 消息确认返回成功
* l:如果是多条,这个就是最后一条消息的tag
* b:是否多条
* */
@Override
public void handleAck(long l, boolean b) throws IOException {
System.out.println("消息发送成功"+l+"是否多条"+b);
if(b){
confirmSet.headSet(l+1).clear();
}else{
confirmSet.remove(l);
}
}

/*消息确认返回失败*/
@Override
public void handleNack(long l, boolean b) throws IOException {
System.out.println("消息发送失败"+l+"是否多条"+b);
if(b){
confirmSet.headSet(l+1).clear();
}else{
confirmSet.remove(l);
}
}
});

String routingKey ="goods.delete";
for (int i = 0; i <10; i++) {
String message = "hello ps"+i;
long tag = channel.getNextPublishSeqNo();
channel.basicPublish(Exchange_NAME,routingKey,null,message.getBytes("utf-8"));
System.out.println(tag);
confirmSet.add(tag);
}
