redis(三)----连接池配置

1. 目录结构:

2. 测试源码

package com.redis;

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

public final class MyRedisPool {
    
    //Redis服务器IP
    private static String ADDR = "127.0.0.1";
    //Redis的端口号
    private static int PORT = 6379;
    //访问密码  未设置密码则为null
    private static String AUTH = null;
    //可用连接实例的最大数目,默认值为8;
    //如果赋值为-1,则表示不限制;如果pool已经分配了maxActive个jedis实例,则此时pool的状态为exhausted(耗尽)。
    private static int MAX_ACTIVE = 1024;
    //控制一个pool最多有多少个状态为idle(空闲的)的jedis实例,默认值也是8。
    private static int MAX_IDLE = 200;
    //等待可用连接的最大时间,单位毫秒,默认值为-1,表示永不超时。
    //如果超过等待时间,则直接抛出JedisConnectionException;
    private static int MAX_WAIT = 10000;
    //在borrow一个jedis实例时,是否提前进行validate操作;如果为true,则得到的jedis实例均是可用的;
    private static boolean TEST_ON_BORROW = true;
    
    private static JedisPool jedisPool = null;
    private static int TIMEOUT = 10000;
    
    //初始化Redis连接池
    static {
        try {
            JedisPoolConfig config = new JedisPoolConfig();          
            config.setMaxTotal(MAX_ACTIVE);
            config.setMaxIdle(MAX_IDLE);
            config.setMaxWaitMillis(MAX_WAIT);
            config.setTestOnBorrow(TEST_ON_BORROW);
            jedisPool = new JedisPool(config, ADDR, PORT, TIMEOUT, AUTH);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    //获取Jedis实例
    public synchronized static Jedis getJedis() {
        try {
            if (jedisPool != null) {
                Jedis resource = jedisPool.getResource();
                return resource;
            } else {
                return null;
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

}
package com.redis;

import redis.clients.jedis.Jedis;

public class TestMain {
    public static void main(String[] args) {
        Jedis jedis = MyRedisPool.getJedis();
        jedis.set("userName", "LYC");
        System.out.println(jedis.get("userName"));
    }
}
