rocketmq学习（三）-springcloud stream rocketmq 函数式编程实现

Maven添加依赖

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-stream-rocketmq</artifactId>
    <version>${spring-cloud-starter-stream-rocketmq.version}</version>

yml配置

消费者和生产者的使用方式为：名称-out-数字的方式用于生产者，名称-in-数字的方式用于消费者。

spring:
	cloud:

	      definition: receive1;receive2;receive3  #重点配置 与 binding 名与消费者对应，多个可以使用；

@RequestMapping("/stream")
@RequiredArgsConstructor
@Slf4j
