redis常用接口实现

在实际工作中，redis通常是作为一个常用的工具类，你只需要调用其即可，所以这里就统计了redis的一些常用接口方法与实现。这里是封装了单机版与集群版本的两种不同实现。

java是基于Jedis的jar包开发的，首先，你需要先下载安装这个jar包，这里就不提供了，直接网上查询就有。如果使用maven构建的话，也是很简单的，如下：这里依赖的是2.7.3版本，这个依赖哪个版本没有明确的规定，根据你自己的情况。<dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.7.3</version></dependency>一：redis常用接口如下：public interface JedisClient {//赋值的方法String set(String key, String value);//获取值的方法String get(String key);//判断是否存在Boolean exists(String key);Long expire(String key, int seconds);Long ttl(String key);Long incr(String key);//hset方法Long hset(String key, String field, String value);//hget方法String hget(String key, String field);//删除 has方法Long hdel(String key, String... field);//判断has是否存在Boolean hexists(String key, String field);List<String> hvals(String key);//删除方法Long del(String key);}二：redis单机版本的实现，代码如下：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;} @Overridepublic String set(String key, String value) {Jedis jedis = jedisPool.getResource();String result = jedis.set(key, value);jedis.close();return result;} @Overridepublic String get(String key) {Jedis jedis = jedisPool.getResource();String result = jedis.get(key);jedis.close();return result;} @Overridepublic Boolean exists(String key) {Jedis jedis = jedisPool.getResource();Boolean result = jedis.exists(key);jedis.close();return result;} @Overridepublic Long expire(String key, int seconds) {Jedis jedis = jedisPool.getResource();Long result = jedis.expire(key, seconds);jedis.close();return result;} @Overridepublic Long ttl(String key) {Jedis jedis = jedisPool.getResource();Long result = jedis.ttl(key);jedis.close();return result;} @Overridepublic Long incr(String key) {Jedis jedis = jedisPool.getResource();Long result = jedis.incr(key);jedis.close();return result;} @Overridepublic Long hset(String key, String field, String value) {Jedis jedis = jedisPool.getResource();Long result = jedis.hset(key, field, value);jedis.close();return result;} @Overridepublic String hget(String key, String field) {Jedis jedis = jedisPool.getResource();String result = jedis.hget(key, field);jedis.close();return result;} @Overridepublic Long hdel(String key, String... field) {Jedis jedis = jedisPool.getResource();Long result = jedis.hdel(key, field);jedis.close();return result;} @Overridepublic Boolean hexists(String key, String field) {Jedis jedis = jedisPool.getResource();Boolean result = jedis.hexists(key, field);jedis.close();return result;} @Overridepublic List<String> hvals(String key) {Jedis jedis = jedisPool.getResource();List<String> result = jedis.hvals(key);jedis.close();return result;} @Overridepublic Long del(String key) {Jedis jedis = jedisPool.getResource();Long result = jedis.del(key);jedis.close();return result;} }三：redis集群版本的实现：具体代码如下：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;} @Overridepublic String set(String key, String value) {return jedisCluster.set(key, value);} @Overridepublic String get(String key) {return jedisCluster.get(key);} @Overridepublic Boolean exists(String key) {return jedisCluster.exists(key);} @Overridepublic Long expire(String key, int seconds) {return jedisCluster.expire(key, seconds);} @Overridepublic Long ttl(String key) {return jedisCluster.ttl(key);} @Overridepublic Long incr(String key) {return jedisCluster.incr(key);} @Overridepublic Long hset(String key, String field, String value) {return jedisCluster.hset(key, field, value);} @Overridepublic String hget(String key, String field) {return jedisCluster.hget(key, field);} @Overridepublic Long hdel(String key, String... field) {return jedisCluster.hdel(key, field);} @Overridepublic Boolean hexists(String key, String field) {return jedisCluster.hexists(key, field);} @Overridepublic List<String> hvals(String key) {return jedisCluster.hvals(key);} @Overridepublic Long del(String key) {return jedisCluster.del(key);} }更多redis知识请关注redis入门教程栏目。以上就是redis常用接口实现的详细内容，更多请关注小潘博客其它相关文章！
