redis的java支持已经做的非常好了，所以我们来试着使用这些api来进行redis的操作，首先我们需要操作redis的架包：

            
     
      redis.clients
             
     
      jedis
             
     
      2.7.3
         
    

我们需要做的仅仅是在spring配置文件中注入这些基本类，然后自己实现dao，下面是配置文件：

            
            
              
              
             
              
              
              
             
         
               
            
              
     
      　　　　　　
                  
                   
                        
                        
                        
                    
                   
                       
                        
                        
                    
                    
                       
                        
                        
                    
                   
              
             
         
       
            
             
                 
                      
       
        127.0.0.1:26379
                   
              
             
         
    

上面配置好了以后，我们就相当于将redis集群给映射过来了，下来我们只需要做一些操作，涉及到数据的CRUD.

package com.yonyou.hotusm.module.nosql.redis;import redis.clients.jedis.ShardedJedis;//这个接口是操作sharedJedispublic interface RedisDataSource {        public abstract ShardedJedis getRedisClient();    public void returnResource(ShardedJedis shardedJedis);    public void returnResource(ShardedJedis shardedJedis,boolean broken);}

实现：

package com.yonyou.hotusm.module.nosql.redis;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;import redis.clients.jedis.ShardedJedis;import redis.clients.jedis.ShardedJedisPool;@Repository("redisDataSource")public class RedisDataSourceImpl implements RedisDataSource {    private static final Logger log = LoggerFactory.getLogger(RedisDataSourceImpl.class);    @Autowired    private ShardedJedisPool    shardedJedisPool;    public ShardedJedis getRedisClient() {        try {            ShardedJedis shardJedis = shardedJedisPool.getResource();            return shardJedis;        } catch (Exception e) {            log.error("getRedisClent error", e);        }        return null;    }    public void returnResource(ShardedJedis shardedJedis) {        shardedJedisPool.close();        //shardedJedisPool.returnResource(shardedJedis);    }    public void returnResource(ShardedJedis shardedJedis, boolean broken) {        if (broken) {            shardedJedisPool.close();            //shardedJedisPool.returnBrokenResource(shardedJedis);        } else {            shardedJedisPool.close();            //shardedJedisPool.returnResource(shardedJedis);        }    }}

 下面就是操作jedis的具体类了：

@Repository("jedisTemplate")public class JedisTemplate {    private static final Logger log = LoggerFactory.getLogger(JedisTemplate.class);    @Autowired    private RedisDataSource     redisDataSource;    public void disconnect() {        ShardedJedis shardedJedis = redisDataSource.getRedisClient();        shardedJedis.disconnect();    }    /**     * 设置单个值     *      * @param key     * @param value     * @return     */    public String set(String key, String value) {        String result = null;        ShardedJedis shardedJedis = redisDataSource.getRedisClient();        if (shardedJedis == null) {            return result;        }        boolean broken = false;        try {            result = shardedJedis.set(key, value);        } catch (Exception e) {            e.printStackTrace();            log.error(e.getMessage(), e);            broken = true;        } finally {            redisDataSource.returnResource(shardedJedis, broken);        }        return result;    }    /**     * 获取单个值     *      * @param key     * @return     */    public String get(String key) {        String result = null;        ShardedJedis shardedJedis = redisDataSource.getRedisClient();        if (shardedJedis == null) {            return result;        }        boolean broken = false;        try {            result = shardedJedis.get(key);        } catch (Exception e) {            log.error(e.getMessage(), e);            broken = true;        } finally {            redisDataSource.returnResource(shardedJedis, broken);        }        return result;    }
