Java操作redis集群

 Java操作redis集群

借助redis的java客户端jedis可以操作以上集群，引用jedis版本的maven坐标如下：

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

Java编写访问redis集群的代码，如下所示：

public class JedisClusterTest {
    public static void main(String[] args) throws IOException {

        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(20);
        config.setMaxIdle(10);
        config.setMinIdle(5);

        Set<HostAndPort> jedisClusterNode = new HashSet<HostAndPort>();
        jedisClusterNode.add(new HostAndPort("192.168.0.61", 8001));
        jedisClusterNode.add(new HostAndPort("192.168.0.62", 8002));
        jedisClusterNode.add(new HostAndPort("192.168.0.63", 8003));
        jedisClusterNode.add(new HostAndPort("192.168.0.61", 8004));
        jedisClusterNode.add(new HostAndPort("192.168.0.62", 8005));
        jedisClusterNode.add(new HostAndPort("192.168.0.63", 8006));

        JedisCluster jedisCluster = null;
        try {
            //connectionTimeout：指的是连接一个url的连接等待时间
            //soTimeout：指的是连接上一个url，获取response的返回等待时间
            jedisCluster = new JedisCluster(jedisClusterNode, 6000, 5000, 10, "zhuge", config);
            System.out.println(jedisCluster.set("cluster", "edsion"));
            System.out.println(jedisCluster.get("cluster"));
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (jedisCluster != null)
                jedisCluster.close();
        }
    }
}

运行效果如下：
OK

集群的Spring Boot整合Redis连接代码示例

1、引入相关依赖：

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

<dependency>
   <groupId>org.apache.commons</groupId>
   <artifactId>commons-pool2</artifactId>
</dependency>

springboot项目核心配置：

server:
  port: 8080

spring:
  redis:
    database: 0
    timeout: 3000
    password: zhuge
    cluster:
      nodes: 192.168.0.61:8001,192.168.0.62:8002,192.168.0.63:8003,192.168.0.61:8004,192.168.0.62:8005,192.168.0.63:8006
   lettuce:
      pool:
        max-idle: 50
        min-idle: 10
        max-active: 100
        max-wait: 1000

代码：

@RestController
public class IndexController {

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

    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    @RequestMapping("/test_cluster")
    public void testCluster() throws InterruptedException {
       stringRedisTemplate.opsForValue().set("edsion", "666");
       System.out.println(stringRedisTemplate.opsForValue().get("edsion"));
    }
}
