如何利用Redis和Scala开发实时数据处理功能

libraryDependencies += "redis.clients" % "jedis" % "3.7.0"

import redis.clients.jedis.Jedis

val jedis = new Jedis("localhost", 6379)

val channel = "realtime_data"
val data = "realtime data example"

jedis.publish(channel, data)

import redis.clients.jedis.{Jedis, JedisPubSub}

val jedis = new Jedis("localhost", 6379)
val channel = "realtime_data"

val sub = new JedisPubSub {
  override def onMessage(channel: String, message: String): Unit = {
    // 处理接收到的实时数据
    println(s"Received realtime data: $message")
  }
}

jedis.subscribe(sub, channel)

import redis.clients.jedis.{Jedis, JedisPubSub}

object RealtimeDataProcessing {
  def main(args: Array[String]): Unit = {
    val jedis = new Jedis("localhost", 6379)
    val channel = "realtime_data"

    val sub = new JedisPubSub {
      override def onMessage(channel: String, message: String): Unit = {
        // 处理接收到的实时数据
        println(s"Received realtime data: $message")
      }
    }

    new Thread(new Runnable {
      override def run(): Unit = {
        jedis.subscribe(sub, channel)
      }
    }).start()

    // 模拟发布实时数据
    new Thread(new Runnable {
      override def run(): Unit = {
        Thread.sleep(1000) // 延迟1秒
        val data = "realtime data example"
        jedis.publish(channel, data)
      }
    }).start()

    Thread.sleep(5000) // 延迟5秒
    jedis.unsubscribe(channel)
    jedis.close()
  }
}
