【Java】SpringBoot中实现Redis Stream队列

在Spring Boot中实现Redis Stream队列，你可以使用spring-boot-starter-data-redis依赖，并利用StreamReceiver来接收消息。以下是一个简单的例子：

1. 添加依赖到你的pom.xml：

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

2. 配置Redis Stream：

@Configuration
public class RedisStreamConfig {
 
    @Autowired
    private RedisConnectionFactory connectionFactory;
 
    @Bean
    public StreamListener streamListener() {
        return new StreamListener();
    }
 
    @Bean
    public StreamReceiver streamReceiver() {
        return new StreamReceiver();
    }
 
    @Bean
    public StreamTemplate streamTemplate() {
        return new StreamTemplate(connectionFactory, "myStreamKey");
    }
}

3. 创建StreamListener来监听Redis Stream：

public class StreamListener {
 
    @Autowired
    private StreamReceiver streamReceiver;
 
    @StreamListener(target = "myStreamKey")
    public void receive(Message<String, Map<String, Object>> message) {
        streamReceiver.receiveMessage(message);
    }
}

4. 实现StreamReceiver来处理接收到的消息：

public class StreamReceiver {
 
    public void receiveMessage(Message<String, Map<String, Object>> message) {
        // 处理消息逻辑
        System.out.println("Received message: " + message.toString());
    }
}

确保你的Redis服务器已启用并运行，并且配置了正确的连接信息。这样，当有消息发送到myStreamKey时，StreamReceiver的receiveMessage方法会被调用，并处理接收到的消息。
