测试类：

package com.haonan.jedis;

import org.junit.Test;
import redis.clients.jedis.Jedis;

/**
 * @author haonan
 * @version 1.0
 * @date 2020/4/6 16:23
 */
public class JedisTest {
    @Test
    public void testjedis() {
        //1.连接redis
        Jedis jedis = new Jedis("localhost", 6379);
        //2.操作redis
        jedis.set("kagome", "inuyasha");
        String kagome = jedis.get("kagome");
        System.out.println(kagome);
        //3.关闭连接
        jedis.close();
    }
}

 

 

小工具类：

配置文件jedis.properties

#fileName jedis.properties
jedis.host=127.0.0.1
jedis.port=6379
jedis.maxTotal=30
jedis.maxIdle=10

 

工具类：

import java.util.ResourceBundle;

/**
 * @author haonan

 * @date 2020/4/6 16:29
 */
public class JedisUtils {
    private static JedisPool jp = null;

    static {
        //getBundle传入配置文件的名称，不用写后缀名称
        ResourceBundle rb = ResourceBundle.getBundle("jedis");

        JedisPoolConfig jpc = new JedisPoolConfig();
        jpc.setMaxTotal(Integer.parseInt(rb.getString("jedis.maxTotal")));
        jpc.setMaxIdle(Integer.parseInt(rb.getString("jedis.maxIdle")));
        jp = new JedisPool(jpc, rb.getString("jedis.host"), Integer.parseInt(rb.getString("jedis.port")));
    }

    public static Jedis getJedis() {
        return jp.getResource();
    }
