# RocketMQ-Reactive-Consumer-Spring

This project aims to help developers quickly integrate [RocketMQ-Spring](https://github.com/apache/rocketmq-spring) with Reactive.

## Features 

- [x] Consuming messages from RocketMQ with Reactive

- [x] Using Spring content ObjectMapper deserialization

## Usage

使用和配置方式类似于 Spring Cloud Stream RocketMQ Binder，但解决一个Stream不能处理流中出现异常无法报告消息失败的[问题](https://github.com/spring-cloud/spring-cloud-stream/issues/2892) 。

application.yml

```yml

rocketmq:

  name-server: 192.168.1.21:9876

  producer:

    group: group-test-producer

  bindings:

    testFunction1-in-0:

      consumer:

        topic: test-topic

        group: group-test-consumer

        retry:

          maxAttempts: 3

          backoff:

            delay: 10000

            multiplier: 0.4

```

consumer

```kotlin

    @Bean

    fun contractCreateChannel(): (Message) -> Mono = { str ->

        Mono.just("${str.payload}").then()

    }

    @Bean

    fun testChannel(): (Message) -> Mono = { str ->

        Mono.just("${str.payload}").doOnNext(::println).thenReturn(ConsumerResult.SUCCESS)

    }

    @Bean

    fun testReplayChannel(): (Message) -> Mono = { str ->

        Mono.just("${str.payload}").doOnNext(::println).thenReturn(ReplayData())

    }

    @Bean

    fun testConsumer1(): Consumer> = object: TypedConsumer>(Consumer { msg ->

            println("Receive New Create Messages: ${msg.payload}")

        }){}

    @Bean

    fun testFunction1() = object: TypedReplayConsumer(Function { msg ->

            Mono.just("${msg}").thenReturn("replay")

        }) {}

```
