2、RedisServiceImpl：获取和放回SharedJedis对象
接口
package org.saiku.redis;
import redis.clients.jedis.ShardedJedis;
public interface RedisService {
public ShardedJedis getRedisClient();

}

4、使用
在需要使用redisClient的地方注入
@Autowired
private RedisClient redisClient;
调用redisClient方法执行增删改查
//不存在就新增
if( !redisClient.exists(auth.getName())){
redisClient.set(redisKey,userInfo.toString());
} //存在才可以删除
if( redisClient.exists(auth.getName())){
redisClient.del(redisKey);
} //获取
String userInfo = redisClient.get(username);
效果：通过查询redis可以看到数据成功的插入到redis了
127.0.0.1:6379> KEYS *
1) "user1"
127.0.0.1:6379> get user1
"user1;pwd2;b1f86e0a-8761-4467-b420-48d9783d3806;tl21uazmvnd4v3ee4bunesms;ROLE_USER"
