Java operating redis client Jedis connection to the cluster (Cluster)

Creating JedisCluster class connection redis clusters.

@Test 

public  void testJedisCluster () throws Exception { 

     // create a connection, JedisCluster objects, in the present embodiment is a single system, 

     the Set <HostAndPort> Nodes = new new HashSet <> (); 

     nodes.add ( new new HostAndPort ( "127.0.0.1 ", 7001 )); 

     nodes.add ( new new HostAndPort (" 127.0.0.1 ", 7002 )); 

     nodes.add ( new new HostAndPort (" 127.0.0.1 ", 7003 )); 

     nodes.add ( new new HostAndPort (" 127.0. 0.1 ", 7004 )); 

     nodes.add ( new new HostAndPort (" 127.0.0.1 ", 7005 )); 

     Nodes.add(new new HostAndPort ( "127.0.0.1", 7006 )); 

     JedisCluster Cluster = new new JedisCluster (Nodes); 

     // perform a method JedisCluster objects, methods, and redis-one correspondence.
