用连接池链接redis

 package com.itheima.utils;

 import redis.clients.jedis.Jedis;
 import redis.clients.jedis.JedisPool;
 import redis.clients.jedis.JedisPoolConfig;

 public class JedisUtils {
     //池子的配置
     private static  JedisPoolConfig poolConfig;
     //池子
     private static JedisPool jedisPool;

     static {
         // 0.创建池子的配置
         poolConfig = new JedisPoolConfig();
         poolConfig.setMaxTotal(10);
         poolConfig.setMinIdle(3);
         String host = "localhost";
         int port = 6379;
         // 1.创建jedis连接池对象
         jedisPool = new JedisPool(poolConfig, host, port);
     }

     // 获得jedis
     public static Jedis getJedis() {
         // 2.从池子里面获取jedis对象
         Jedis jedis = jedisPool.getResource();
         return jedis;
     }

 }
