Spring 整合 Redis

接口

package com.util.redis;
/**
 _Redis工具接口_ 
 */
public interface RedisUtils {
/**
 _保存_ 
 _ @param key
 _            键
 _ @param value
 _            值

/*_

###### 单机版实现类

package com.util.redis.impl;
import org.springframework.beans.factory.annotation.Autowired;
import com.util.redis.RedisUtils;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
/**
 _Redis连接池工具类_ 
 */
public class RedisPool implements RedisUtils {
@Autowired
private JedisPool jedisPool;
@Override
public void set(String key, String value) {
    Jedis jedis = this.getJedis();
    jedis.set(key, value);
    this.releaseJedis(jedis);
}
@Override
public void set(String key, String value, Integer seconds) {
    Jedis jedis = this.getJedis();
    jedis.set(key, value);
    jedis.expire(key, seconds);
    this.releaseJedis(jedis);
}
@Override
public String get(String key) {
    Jedis jedis = this.getJedis();
    String result = jedis.get(key);
    this.releaseJedis(jedis);
    return result;
}
@Override
public void del(String key) {
    Jedis jedis = this.getJedis();
    jedis.del(key);
    this.releaseJedis(jedis);
}
@Override
public void expire(String key, Integer seconds) {
    Jedis jedis = this.getJedis();
    jedis.expire(key, seconds);
    this.releaseJedis(jedis);
}
/**
 _获取Jedis连接_ 
 _@return Jedis连接_ /
public Jedis getJedis() {
    return this.jedisPool.getResource();
}
/_*
 _ 释放Jedis连接
  @param jedis
 _jedis连接_ /
public void releaseJedis(Jedis jedis) {

###### 集群版实现类

package com.util.redis.impl;
import org.springframework.beans.factory.annotation.Autowired;
import com.util.redis.RedisUtils;
import redis.clients.jedis.JedisCluster;
/**
 _Redis集群工具类_ 
 */
public class RedisCluster implements RedisUtils {
@Autowired
private JedisCluster jedisCluster;
@Override
public void set(String key, String value) {
    this.jedisCluster.set(key, value);
}
@Override
public void set(String key, String value, Integer seconds) {
    this.jedisCluster.set(key, value);
    this.jedisCluster.expire(key, seconds);
}
@Override
public String get(String key) {
    return this.jedisCluster.get(key);
}
@Override
public void del(String key) {
    this.jedisCluster.del(key);
}
@Override
public void expire(String key, Integer seconds) {
    this.jedisCluster.expire(key, seconds);
}
/**
 _ 获取JedisCluster对象
 _ 可以直接使用它来进行redis操作
  @return JedisCluster对象
 */
public JedisCluster getJedisCluster() {
    return jedisCluster;
}
}
