這裡說的三種工作模式是指：

    1、單機模式

    2、分片模式

    3、叢集模式（since 3.0）

說明圖詳見以下：

使用jedis連線模式一：    

//初始化連線
private Jedis jedis=new Jedis("192.168.0.100", 6379);
jedis.set("a","b");
jedis.hmset(key, hash);
……

使用jedis連線模式二：   

        GenericObjectPoolConfig config=new GenericObjectPoolConfig();
        config.setMaxIdle(32
 
); 
        config.setMinIdle(12);
        config.setTestOnBorrow(true); 
        config.setTestOnReturn(rtrue);
        config.setTestWhileIdle(true);
        List<JedisShardInfo> shards = new ArrayList<JedisShardInfo>(); 
        for (int i = 0; i < shareds.size(); i++) {
        	shards.add(new
 
 JedisShardInfo("192.168.0.100", 6379, 200)); 
	}
        // 構造池 
        ShardedJedisPool shardedJedisPool= new ShardedJedisPool(config, shards);
        ShardedJedis jedis=shardedJedisPool.getResource();
        jedis.set("a","b");
        jedis.hmset(key, hash);
        ……

使用jedis連線模式三：

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

		for (int i = 0; i < shareds.size(); i++) {
			jedisClusterNodes.add(new HostAndPort("192.168.0.100",6379));
		}
		// 構造池
		BinaryJedisCluster cluster= new BinaryJedisCluster(jedisClusterNodes);
		cluster.set("a","b");
                cluster.hmset(key, hash);
                ……

public class BinaryJedisCluster extends JedisCluster {

    public String set(final String key, final byte[] value) {
        return new JedisClusterCommand<String>(connectionHandler, timeout,
                maxRedirections) {

            public String execute(Jedis connection) {
                return connection.set(SafeEncoder.encode(key), value);
            }
        }.run(key);
    }

    public byte[] getBytes(final String key) {
        return new JedisClusterCommand<byte[]>(connectionHandler, timeout,
                maxRedirections) {

            public byte[] execute(Jedis connection) {
                return connection.get(SafeEncoder.encode(key));
            }
        }.run(key);
    }


    public Set<byte[]> zrevrangeByScoreBytes(final String key, final double max,
                                        final double min, final int offset, final int count) {
        return new JedisClusterCommand<Set<byte[]>>(connectionHandler, timeout,
                maxRedirections) {

            public Set<byte[]> execute(Jedis connection) {
                return connection.zrevrangeByScore(SafeEncoder.encode(key),
                        max, min, offset, count);
            }
        }.run(key);
    }


    public Set<byte[]> zrevrangeByScoreBytes(final String key, final String max,
                                        final String min, final int offset, final int count) {
        return new JedisClusterCommand<Set<byte[]>>(connectionHandler, timeout,
                maxRedirections) {

            public Set<byte[]> execute(Jedis connection) {
                return connection.zrevrangeByScore(SafeEncoder.encode(key),
                        SafeEncoder.encode(max), SafeEncoder.encode(min), offset, count);
            }
        }.run(key);
    }


    public Long linsert(final String key, final LIST_POSITION where,
                        final byte[] pivot, final byte[] value) {
        return new JedisClusterCommand<Long>(connectionHandler, timeout,
                maxRedirections) {

            public Long execute(Jedis connection) {
                return connection.linsert(SafeEncoder.encode(key), where,
                        pivot, value);
            }
        }.run(key);
    }


    public Long lpushx(final String key, final byte[]... string) {
        return new JedisClusterCommand<Long>(connectionHandler, timeout,
                maxRedirections) {

            public Long execute(Jedis connection) {
                return connection.lpushx(SafeEncoder.encode(key), string);
            }
        }.run(key);
    }


    public Long rpushx(final String key, final byte[]... string) {
        return new JedisClusterCommand<Long>(connectionHandler, timeout,
                maxRedirections) {

            public Long execute(Jedis connection) {
                return connection.rpushx(SafeEncoder.encode(key), string);
            }
        }.run(key);
    }


    public List<byte[]> blpopBytes(final String arg) {
        return new JedisClusterCommand<List<byte[]>>(connectionHandler,
                timeout, maxRedirections) {

            public List<byte[]> execute(Jedis connection) {
                return connection.blpop(SafeEncoder.encode(arg));
            }
        }.run(null);
    }


    public List<byte[]> brpopBytes(final String arg) {
        return new JedisClusterCommand<List<byte[]>>(connectionHandler,
                timeout, maxRedirections) {

            public List<byte[]> execute(Jedis connection) {
                return connection.brpop(SafeEncoder.encode(arg));
            }
        }.run(null);
    }
