Test.java（测试类）：

package cn.e3mall.jedis;

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

import cn.e3mall.common.jedis.JedisClient;

public class Test {

	@Test
	public void testJedisClient() throws Exception {
		//初始化spring容器
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-redis.xml");
		//从容器中获得JedisClient接口的对象  (面向接口编程)
		JedisClient jedisClient = applicationContext.getBean(JedisClient.class);  //通过接口获取不同的实现类对象。  
		jedisClient.set("mytest", "jedisClient");
		String string = jedisClient.get("mytest");
		System.out.println(string);
		
	}
}

用到的工具类如下：

JedisClient.java（自定义的接口,单机版Redis以及集群版Redis都要实现该接口）：

package cn.e3mall.common.jedis;

import java.util.List;

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);
	Boolean hexists(String key, String field);
	List<String> hvals(String key);
	Long del(String key);
}

JedisClientPool.java（单机版Redis,实现自定义的JedisClient接口）：

package cn.e3mall.common.jedis;

import java.util.List;

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;
	}

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

	@Override
	public List<String> hvals(String key) {
		Jedis jedis = jedisPool.getResource();
		List<String> result = jedis.hvals(key);
		jedis.close();
		return result;
	}

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

}

JedisClientCluster.java（集群版Redis,实现自定义的JedisClient接口）：

package cn.e3mall.common.jedis;

import java.util.List;

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);
	}

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

	@Override
	public List<String> hvals(String key) {
		return jedisCluster.hvals(key);
	}

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

}
