RedisUtil工具類

1.添加Redis依賴包

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

2.RedisUtil實現代碼

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); //最大可用連接數
            jedisPoolConfig.setBlockWhenExhausted(true); //連接耗盡后是否等待
            jedisPoolConfig.setMaxWaitMillis(2000); //等待時間
            jedisPoolConfig.setMaxIdle(5); //最大閑置連接數
            jedisPoolConfig.setMinIdle(5); //最小閑置連接數
            jedisPoolConfig.setTestOnBorrow(true); //連接的時候測試一下ping pong
            jedisPool=new JedisPool(jedisPoolConfig,"hadoop102",6379,1000) ;
            System.out.println("開辟連接池");
            return jedisPool.getResource();
        }else{
            return jedisPool.getResource();
        }
    }
}
