Redis java client operating cluster

1. Use Jedis java to natively operate redis cluster

public class RedisCluster {
    public static void main(String[] args) {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxTotal(20);
        jedisPoolConfig.setMaxIdle(10);
        jedisPoolConfig.setMinIdle(5);

        Set<HostAndPort> clusterNodes = new HashSet<HostAndPort>();
        clusterNodes.add(new HostAndPort("192.168.0.101", 8001));
        clusterNodes.add(new HostAndPort("192.168.0.101", 8004));
        clusterNodes.add(new HostAndPort("192.168.0.102", 8002));
        clusterNodes.add(new HostAndPort("192.168.0.102", 8005));
        clusterNodes.add(new HostAndPort("192.168.0.103", 8003));
        clusterNodes.add(new HostAndPort("192.168.0.103", 8006));

        JedisCluster jedisClusterPool = new JedisCluster(clusterNodes, 6000, 5000, 10, "allen", jedisPoolConfig);
        System.out.println(jedisClusterPool.set("jedisClusterTest", "hello world jedisClusterTest Tset"));
        System.out.println(jedisClusterPool.get("jedisClusterTest"));
    }
}

Execution structure:

OK
hello world jedisClusterTest Tset

Process finished with exit code 0

View the setting results from the cluster:

192.168.0.103:8003> keys *
1) "SentinelTest2"
2) "jedisClusterTest"
192.168.0.103:8003> get jedisClusterTest
"hello world jedisClusterTest Tset"

2. Use springboot to operate redis cluster

1. Startup:

@SpringBootApplication
public class ApplicationStarter {
    public static void main(String[] args) {
        SpringApplication.run(ApplicationStarter.class,args);
    }
}

 2. Service category:

@RestController
public class IndexController {
    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    //@RequestMapping("/SentinelTest")
    @RequestMapping("/ClusterRedisTest")
   public void testSentinel() throws InterruptedException {
       int i = 1;
       while(true){
           try {
               stringRedisTemplate.opsForValue().set("SentinelTest2", i++ + "");
               System.out.println("successed set SentinelTest2 to " + i);
               Thread.sleep(1000);
           }catch (Exception e){
               System.out.println(e);
           }
       }
   }
}

Spring configuration redis cluster

server:
  port: 8080

spring:
  redis:
    database: 0
    timeout: 3000
    password: allen
    cluster:
      nodes: 192.168.0.101:8001,192.168.0.101:8004,192.168.0.102:8002,192.168.0.102:8005,192.168.0.103:8003,192.168.0.103:8006
    lettuce:
      pool:
        max‐idle: 50
        min‐idle: 10
        max‐active: 100
        max‐wait: 1000
