关于redis:RedisUtil

1.增加Redis依赖包

 <dependency>    <groupId>redis.clients</groupId>    <artifactId>jedis</artifactId>    <version>3.3.0</version></dependency>

2.RedisUtil实现代码

import redis.clients.jedis.Jedis;import redis.clients.jedis.JedisPool;import redis.clients.jedis.JedisPoolConfig;/** * description * created by A on 2021/3/26 */public class RedisUtil1 {    public static JedisPool jedisPool=null;    public static Jedis getJedis(){        if(jedisPool==null){            JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();            jedisPoolConfig.setMaxTotal(100); //最大可用连接数            jedisPoolConfig.setBlockWhenExhausted(true); //连贯耗尽后是否期待            jedisPoolConfig.setMaxWaitMillis(2000); //等待时间            jedisPoolConfig.setMaxIdle(5); //最大闲置连接数            jedisPoolConfig.setMinIdle(5); //最小闲置连接数            jedisPoolConfig.setTestOnBorrow(true); //连贯的时候测试一下ping pong            jedisPool=new JedisPool(jedisPoolConfig,"hadoop102",6379,1000) ;            System.out.println("开拓连接池");            return jedisPool.getResource();        }else{            return jedisPool.getResource();        }    }}
