springcloud整合stream,rabbitmq实现消息驱动功能

1.代码实现：

创建项目stream

添加依赖

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.2</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.cxh</groupId>
    <artifactId>stream</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>stream</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>8</java.version>
        <spring-cloud-alibaba-dependencies.version>2021.1</spring-cloud-alibaba-dependencies.version>
        <spring-cloud-dependencies.version>2021.0.0</spring-cloud-dependencies.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>$spring-cloud-dependencies.version</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>$spring-cloud-alibaba-dependencies.version</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
        </dependency>
    </dependencies>

监听类

@EnableBinding(Sink.class)
public class SinkReceiver 

    private static Logger logger = LoggerFactory.getLogger(SinkReceiver.class);

    @StreamListener(Sink.INPUT)
    public void receive(String payload) 
        logger.info("Received: " + payload);
    

2.实现效果：

启动rabbitmq, 项目stream

打开浏览器​​http://localhost:15672/​​，使用账号密码guest登录rabbitmq, 在队列中发现消息：

测试send

 查看控制台消息：

com.cxh.stream.SinkReceiver              : Received: 测试send
