}
获取连接
@Component
public class JedisUtils {
@Autowired
JedisPool jedisPool;
public Jedis getJedis() {
return jedisPool.getResource();
}
运用，一定要关闭！！！
Jedis jedis = null;
try {
jedis = jedisUtils.getJedis();
jedis.set(remind.getRemindTm(), JSON.toJSONString(remind));
} finally {
if (jedis != null) {
jedis.close();
}
}
