本文主要是介绍Redis-操作测试，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

Jedis所需要的jar包

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>3.2.0</version>
</dependency>

连接Redis注意事项

禁用Linux的防火墙：Linux(CentOS7)里执行命令
systemctl stop/disable firewalld.service   
redis.conf中注释掉bind 127.0.0.1 ,然后 protected-mode no

创建测试程序

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

import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;

public class JedisDemo1 {

    public static void main(String[] args) {
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.121.160", 6379);
        //测试
        String value = jedis.ping();
        System.out.println(value);
    }

    //操作key
    @Test
    public void demo1(){
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.121.160", 6379);

        //添加
        jedis.set("name","lucy");

        //获取
        String name = jedis.get("name");
        System.out.println(name);

        Set<String> keys = jedis.keys("*");
        for (String key : keys) {
            System.out.println(key);
        }

    }

    //操作String
    @Test
    public void demo2(){
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.121.160", 6379);

        //设置多个key-value
        jedis.mset("k1","v1","k2","v2");
        List<String> mget = jedis.mget("k1", "k2");
        System.out.println(mget);
    }

    //操作List
    @Test
    public void demo3(){
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.121.160", 6379);

        jedis.lpush("key1","lucy","mary","jack");
        List<String> value = jedis.lrange("key1", 0, -1);
        System.out.println(value);
    }

    //操作set
    @Test
    public void demo4(){
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.121.160", 6379);

        jedis.sadd("name","lucy","jack");
        Set<String> smembers = jedis.smembers("name");
        for (String name : smembers) {
            System.out.println(name);
        }
        jedis.srem("name","lucy");
    }

    //操作hash
    @Test
    public void demo5(){
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.121.160", 6379);

        jedis.hset("users","age","20");
        String hget = jedis.hget("users", "age");
        System.out.println(hget);

        Map<String,String> map = new HashMap<String,String>();
        map.put("telphone","13810169999");
        map.put("address","donglin");
        map.put("email","abc@163.com");
        jedis.hmset("hash2",map);
        List<String> result = jedis.hmget("hash2", "telphone","email");
        for (String element : result) {
            System.out.println(element);
        }

    }

    //操作zset
    @Test
    public void demo6(){
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.121.160", 6379);

        jedis.zadd("zset01", 100d, "成都");
        jedis.zadd("zset01", 90d, "上海");
        jedis.zadd("zset01", 80d, "北京");
        jedis.zadd("zset01", 70d, "广州");

        Set<String> zrange = jedis.zrange("zset01", 0, -1);
        for (String e : zrange) {
            System.out.println(e);
        }
    }
}
