2.  使用 help+命令

在IDEA使用Jedis操作Redis

常规使用

引入依赖

我的测试

package com.leo.test;import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import redis.clients.jedis.Jedis;
import org.junit.jupiter.api.Test;public class TestRedis {private Jedis jedis;@BeforeEachvoid setUp() {// 1.建立连接jedis = new Jedis("192.168.**.**", 6379);  //根据自己的ip// 2.设置密码jedis.auth("***");   自己的密码// 3.选择库jedis.select(0);}@Testvoid testString() {// 存入数据String result = jedis.set("name2", "大哥");System.out.println("result = " + result);// 获取数据String name = jedis.get("name2");System.out.println("name = " + name);}@AfterEachvoid tearDown() {if (jedis != null) {jedis.close();}}
}

Jedis的连接池

1.配置Jedis连接池工具类

package Utils;import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;public class JedisConnectionFactory {private static final JedisPool jedisPool;static {//配置连接池JedisPoolConfig poolConfig = new JedisPoolConfig();poolConfig.setMaxTotal(8);poolConfig.setMaxIdle(8);poolConfig.setMinIdle(0);poolConfig.setMaxWaitMillis(1000);//创建连接池对象jedisPool = new JedisPool(poolConfig,"192.168.88.134",6379,1000,"123321");}public static Jedis getJedis(){return jedisPool.getResource();}
}

建立连接使用工具类 

package com.leo.test;import Utils.JedisConnectionFactory;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import redis.clients.jedis.Jedis;
import org.junit.jupiter.api.Test;
import redis.clients.jedis.JedisFactory;
import redis.clients.jedis.JedisPool;public class TestRedis {private Jedis jedis;@BeforeEachvoid setUp() {// 1.建立连接//  方式1// jedis = new Jedis("192.168.88.134", 6379);//  方式2jedis= JedisConnectionFactory.getJedis();// 2.设置密码jedis.auth("123321");// 3.选择库jedis.select(0);}@Testvoid testString() {// 存入数据String result = jedis.set("name3", "小弟");System.out.println("result = " + result);// 获取数据String name = jedis.get("name3");System.out.println("name = " + name);}@AfterEachvoid tearDown() {if (jedis != null) {jedis.close();}}
}
