scala对redis集群操作工具类 附带java版本的工具类以及spring配置

• Scala的工具类如下:

package cn.lijieimport java.utilimport redis.clients.jedis.{HostAndPort, JedisCluster}import scala.collection.JavaConversions._import scala.collection.mutable/**  * User: lijie  */object RedisClient {  val clients = RedisConnector.clients  /**    *    * @param key    * @param value    * @return    */  def set(key: String, value: String): Unit = {    clients.set(key, value)  }  /**    *    * @param key    * @return    */  def get(key: String): Option[String] = {    val value = clients.get(key)    if (value == null)      None    else      Some(value)  }  /**    *    * @param key    */  def del(key: String): Unit = {    clients.del(key)  }  /**    *    * @param hkey    * @param key    * @param value    * @return    */  def hset(hkey: String, key: String, value: String): Boolean = {    clients.hset(hkey, key, value) == 1  }  /**    *    * @param hkey    * @param key    * @return    */  def hget(hkey: String, key: String): Option[String] = {    val value = clients.hget(hkey, key)    if (value == null)      None    else      Some(value)  }  /**    *    * @param hkey    * @param key    * @return    */  def hdel(hkey: String, key: String): Option[Long] = {    Some(clients.hdel(hkey, key))  }  /**    *    * @param hkey    * @param map    */  def hmset(hkey: String, map: mutable.Map[String, String]): Unit = {    clients.hmset(hkey, mapAsJavaMap(map))  }  /**    *    * @param key    * @param value    * @return    */  def rpush(key: String, value: String): Option[Long] = {    Some(clients.rpush(key, value))  }  /**    *    * @param key    * @return    */  def lpop(key: String): Option[String] = {    val value = clients.lpop(key)    if (value == null)      None    else      Some(value)  }  /**    *    * @param key    * @return    */  def lhead(key: String): Option[String] = {    val head = clients.lindex(key, 0)    if (head == null)      None    else      Some(head)  }  /**    *    * @param key    * @return    */  def incr(key: String): Option[Long] = {    val inc = clients.incr(key)    if (inc == null)      None    else      Some(inc)  }  /**    *    * @param key    * @param time    * @return    */  def expire(key: String, time: Int) = {    clients.expire(key, time)  }  /**    *    * @param key    * @return    */  def ttl(key: String): Option[Long] = {    Some(clients.ttl(key))  }}object RedisConnector {  private val jedisClusterNodes = new util.HashSet[HostAndPort]()  jedisClusterNodes.add(new HostAndPort("10.0.4.140", 7000))  jedisClusterNodes.add(new HostAndPort("10.0.4.141", 7001))  jedisClusterNodes.add(new HostAndPort("10.0.4.142", 7002))  jedisClusterNodes.add(new HostAndPort("10.0.4.143", 7003))  jedisClusterNodes.add(new HostAndPort("10.0.4.144", 7004))  val clients = new JedisCluster(jedisClusterNodes)}object MainClass {  def main(args: Array[String]): Unit = {    val dao = RedisClient    //    dao.set("lijie", "123")    //    dao.del("lijie")    //    println(dao.get("lijie"))    //    dao.hset("myhset", "lijie1", "chongqing")    //    dao.hset("myhset", "lijie2", "shenzheng")    //    println(dao.hget("myhset", "lijie1"))    //    dao.hdel("myhset", "lijie1")    //    dao.rpush("myfifo", "a")    //    dao.rpush("myfifo", "c")    //    dao.rpush("myfifo", "b")    //    //    println(dao.lhead("myfifo"))    //    //    println(dao.lpop("myfifo"))    //    println(dao.lpop("myfifo"))    //    println(dao.lpop("myfifo"))    //    println(dao.incr("myincr"))  }}

java版本的如下:
其中JedisClient是一个总接口,单机版和集群版本都实现了他的方法

• JedisClient:

/** *  * @author 黎杰 */public interface JedisClient {    String get(String key);    String set(String key, String value);    String hget(String hkey, String key);    long hset(String hkey, String key, String value);    long incr(String key);    long expire(String key, int second);    long ttl(String key);    long del(String key);    long hdel(String hkey, String key);}

• JedisClientCluster:

import org.springframework.beans.factory.annotation.Autowired;import cn.ecar.web.dao.redisdao.JedisClient;import redis.clients.jedis.JedisCluster;/** *  * @author 黎杰 */public class JedisClientCluster implements JedisClient {    @Autowired    private JedisCluster jedisCluster;    @Override    public String get(String key) {        return jedisCluster.get(key);    }    @Override    public String set(String key, String value) {        return jedisCluster.set(key, value);    }    @Override    public String hget(String hkey, String key) {        return jedisCluster.hget(hkey, key);    }    @Override    public long hset(String hkey, String key, String value) {        return jedisCluster.hset(hkey, key, value);    }    @Override    public long incr(String key) {        return jedisCluster.incr(key);    }    @Override    public long expire(String key, int second) {        return jedisCluster.expire(key, second);    }    @Override    public long ttl(String key) {        return jedisCluster.ttl(key);    }    @Override    public long del(String key) {        return jedisCluster.del(key);    }    @Override    public long hdel(String hkey, String key) {        return jedisCluster.hdel(hkey, key);    }}

• JedisClientSingle:

import org.springframework.beans.factory.annotation.Autowired;import cn.ecar.web.dao.redisdao.JedisClient;import redis.clients.jedis.Jedis;import redis.clients.jedis.JedisPool;/** * @author 黎杰 */public class JedisClientSingle implements JedisClient {    @Autowired    private JedisPool jedisPool;    @Override    public String get(String key) {        Jedis jedis = jedisPool.getResource();        String string = jedis.get(key);        jedis.close();        return string;    }    @Override    public String set(String key, String value) {        Jedis jedis = jedisPool.getResource();        String string = jedis.set(key, value);        jedis.close();        return string;    }    @Override    public String hget(String hkey, String key) {        Jedis jedis = jedisPool.getResource();        String string = jedis.hget(hkey, key);        jedis.close();        return string;    }    @Override    public long hset(String hkey, String key, String value) {        Jedis jedis = jedisPool.getResource();        Long result = jedis.hset(hkey, key, value);        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 expire(String key, int second) {        Jedis jedis = jedisPool.getResource();        Long result = jedis.expire(key, second);        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 del(String key) {        Jedis jedis = jedisPool.getResource();        Long result = jedis.del(key);        jedis.close();        return result;    }    @Override    public long hdel(String hkey, String key) {        Jedis jedis = jedisPool.getResource();        Long result = jedis.hdel(hkey, key);        jedis.close();        return result;    }}

• java版本spring的配置:
