jedis连接单机版和集群版redis

1 JedisClient接口

代码语言：javascript复制

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）

代码语言：javascript复制

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）

代码语言：javascript复制

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);
	}

}
