import java.time.Duration

import io.lettuce.core.RedisURI
import io.lettuce.core.cluster.api.StatefulRedisClusterConnection
import io.lettuce.core.cluster.{ClusterClientOptions, ClusterTopologyRefreshOptions, RedisClusterClient}

import scala.collection.immutable

object RedisUtils {

  val ip = "10.110.122.172"
  val ports = Array(, , , , , )

  def getRediceConnect: StatefulRedisClusterConnection[String, String] = {
    val uris: immutable.Seq[RedisURI] = ports.map(port => {
      RedisURI.builder().withHost(ip).withPort(port).build()
    }).toList
    import scala.collection.JavaConverters._
    val redisClusterClient = RedisClusterClient.create(uris.asJava)
    val topologyRefreshOptions = ClusterTopologyRefreshOptions.builder.enablePeriodicRefresh(Duration.ofMinutes()).enableAllAdaptiveRefreshTriggers.build
    redisClusterClient.setOptions(ClusterClientOptions.builder.autoReconnect(true).pingBeforeActivateConnection(true).topologyRefreshOptions(topologyRefreshOptions).build)
    redisClusterClient.connect()
  }

}

测试:

package com.wenbronk.sparkstreaming.test

import com.wenbronk.sparkstreaming.scala.commons.RedisUtils
import org.scalatest.FunSuite

class RedisTests extends FunSuite{

  test("redisSet") {
    val utils = RedisUtils
    val connect = utils.getRediceConnect
    connect.async().set("abc", "")
    println("hello")
  }

  test("redisGet") {
    val utils = RedisUtils
    val connect = utils.getRediceConnect
    val value = connect.async().get("abc")
    println(value.get())
  }

  test("flushdb") {
    val utils = RedisUtils
    val connect = utils.getRediceConnect
    val value = connect.async().flushdb()
    println(value.get())
