1 JedisClient接口

package com.shi.jedis;

public interface JedisClient {

	String set(String key, String value);
	String get(String key);
	Boolean exists(String key);
	Long expire(String key, int seconds);
	Long ttl(String key);
	Long incr(String key);
	Long hset(String key, String field, String value);
	String hget(String key, String field);
	Long hdel(String key, String... field);
}

2 JedisClientPool 类（单机版实现类）

package com.shi.jedis;

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;

public class JedisClientPool implements JedisClient {
	
	private JedisPool jedisPool;

	public JedisPool getJedisPool() {
		return jedisPool;
	}

	public void setJedisPool(JedisPool jedisPool) {
		this.jedisPool = jedisPool;
	}

	@Override
	public String set(String key, String value) {
		Jedis jedis = jedisPool.getResource();
		String result = jedis.set(key, value);
		jedis.close();
		return result;
	}

	@Override
	public String get(String key) {
		Jedis jedis = jedisPool.getResource();
		String result = jedis.get(key);
		jedis.close();
		return result;
	}

	@Override
	public Boolean exists(String key) {
		Jedis jedis = jedisPool.getResource();
		Boolean result = jedis.exists(key);
		jedis.close();
		return result;
	}

	@Override
	public Long expire(String key, int seconds) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.expire(key, seconds);
		jedis.close();
		return result;
	}

	@Override
	public Long ttl(String key) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.ttl(key);
		jedis.close();
		return result;
	}

	@Override
	public Long incr(String key) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.incr(key);
		jedis.close();
		return result;
	}

	@Override
	public Long hset(String key, String field, String value) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.hset(key, field, value);
		jedis.close();
		return result;
	}

	@Override
	public String hget(String key, String field) {
		Jedis jedis = jedisPool.getResource();
		String result = jedis.hget(key, field);
		jedis.close();
		return result;
	}

	@Override
	public Long hdel(String key, String... field) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.hdel(key, field);
		jedis.close();
		return result;
	}

}

3 JedisClientCluster （集群版实现类）

package com.shi.jedis;

import redis.clients.jedis.JedisCluster;

public class JedisClientCluster implements JedisClient {
	
	private JedisCluster jedisCluster;

	public JedisCluster getJedisCluster() {
		return jedisCluster;
	}

	public void setJedisCluster(JedisCluster jedisCluster) {
		this.jedisCluster = jedisCluster;
	}

	@Override
	public String set(String key, String value) {
		return jedisCluster.set(key, value);
	}

	@Override
	public String get(String key) {
		return jedisCluster.get(key);
	}

	@Override
	public Boolean exists(String key) {
		return jedisCluster.exists(key);
	}

	@Override
	public Long expire(String key, int seconds) {
		return jedisCluster.expire(key, seconds);
	}

	@Override
	public Long ttl(String key) {
		return jedisCluster.ttl(key);
	}

	@Override
	public Long incr(String key) {
		return jedisCluster.incr(key);
	}

	@Override
	public Long hset(String key, String field, String value) {
		return jedisCluster.hset(key, field, value);
	}

	@Override
	public String hget(String key, String field) {
		return jedisCluster.hget(key, field);
	}

	@Override
	public Long hdel(String key, String... field) {
		return jedisCluster.hdel(key, field);
	}

}

4 测试类

package com.shi.page;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.shi.jedis.JedisClient;

/**
 * 
 * @author: SHF
 * @date: 2018年3月2日 下午5:03:26
 * @Description:使用JedisClient工具类来连接单机版的redis和集群版的redis
 */
public class JedisClusterTest {
	
	@Test
	public void testJedisCluster()throws Exception{
		//1 初始化spring容器
		ApplicationContext applicationContext=new ClassPathXmlApplicationContext("classpath:spring/applicationContext-jedis.xml");
		//2 从容器中获取JedisClient对象
		JedisClient jedisClient=applicationContext.getBean(JedisClient.class);
		//3 使用jedisClient操作redis对像
		jedisClient.set("mytest", "jedisClient");
		String string=jedisClient.get("mytest");
		System.out.println("jedisClient="+string);
	}
}
