spring-cloud-stream-binder-rocketmq 不支持延时队列，需要使用原生的mq进行消息发送。

一、引入依赖

 implementation 'com.alibaba.cloud:spring-cloud-stream-binder-rocketmq:2.1.0.RELEASE'

二、定义生产信道和消费信道

//消费信道
public interface PagePointSink {
   
    String PAGE_POINT_INPUT = "page_point_input";

    @Input(PAGE_POINT_INPUT)
    SubscribableChannel pagepointInput();
}

//生产信道
public interface PagePointSource {
   
    String PAGE_POINT_OUTPUT = "page_point_output";

    @Output(PAGE_POINT_OUTPUT)
    MessageChannel pagepointOutput();
}

三、配置文件配置

spring.cloud.stream.bindings.page_point_output.destination=page_point
spring.cloud.stream.bindings.page_point_output.content-type=application/json
spring.cloud.stream.bindings.page_point_input.destination=page_point
spring.cloud.stream.bindings.page_point_input.content-type=application/json
spring.cloud.stream.bindings.page_point_input.group=page_point_input

四、延时发送

1、生产端
