> 在springboot2.2.0.RELEASE版本之前是amqp正式支持的属性，用来配置消息发送到交换器之后是否触发回调方法，在2.2.0及之后该属性过期使用spring.rabbitmq.publisher-confirm-type属性配置代替，用来配置更多的确认类型；

##### 1.spring.rabbitmq.publisher-confirm发布确认属性配置 #####

如果该属性为true，则会触发以下方法：

/** * 设置生产者消息publish-confirm回调函数 */
            rabbitTemplate.setConfirmCallback((correlationData, ack, cause) -> { 
                if(!ack){ 
                    LoggerUtil.error(RabbitConfig.class, StringUtils.join("publishConfirm消息发送到交换器被退回，Id：", correlationData.getId(), ";退回原因是：", cause));
                } else { 
                    LoggerUtil.info(RabbitConfig.class, "发送消息到交换器成功,MessageId:"+correlationData.getId());
                }
            });

##### 2.spring.rabbitmq.publisher-confirm-type新版发布确认属性有三种确认类型 #####

/** * The type of publisher confirms to use. */
    	public enum ConfirmType { 
    
    		/** * Use {@code RabbitTemplate#waitForConfirms()} (or {@code waitForConfirmsOrDie()} * within scoped operations. */
    		SIMPLE,
    
    		/** * Use with {@code CorrelationData} to correlate confirmations with sent * messsages. */
    		CORRELATED,
    
    		/** * Publisher confirms are disabled (default). */
    		NONE
    
    	}

*  NONE值是禁用发布确认模式，是默认值
 *  CORRELATED值是发布消息成功到交换器后会触发回调方法，如1示例
 *  SIMPLE值经测试有两种效果，其一效果和CORRELATED值一样会触发回调方法，其二在发布消息成功后使用rabbitTemplate调用waitForConfirms或waitForConfirmsOrDie方法等待broker节点返回发送结果，根据返回结果来判定下一步的逻辑，要注意的点是waitForConfirmsOrDie方法如果返回false则会关闭channel，则接下来无法发送消息到broker;
