API访问 redis集群

-----------------------------

 

代码

@Test

public void testRedisCluster() throws IOException {

    Set<HostAndPort> hosts = new HashSet<HostAndPort>();

    hosts.add(new HostAndPort("192.168.116.101", 7000));

    hosts.add(new HostAndPort("192.168.116.101", 7001));

    hosts.add(new HostAndPort("192.168.116.101", 7002));

    hosts.add(new HostAndPort("192.168.116.101", 7003));

    hosts.add(new HostAndPort("192.168.116.101", 7004));

    hosts.add(new HostAndPort("192.168.116.101", 7005));

    BinaryJedisCluster cluster = new BinaryJedisCluster(hosts);

    byte[] value = cluster.get("key1".getBytes());

    System.out.println(new String(value));

    cluster.close();

}
