## 六、Jedsi操作Redis ##

### 6.1 常用操作 ###

**jedis所需的依赖**

<dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>3.3.0</version>
    </dependency>

**连接Redis的注意事项**

*  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

**测试程序**

/**
     * @author cVzhanshi
     * @create 2021-07-28 9:13
     */
    public class JedisDemo1 {
        
        public static void main(String[] args) {
        
            //创建Jedis对象
            Jedis jedis = new Jedis("192.168.242.110", 6379);
            //测试
            String ping = jedis.ping();
            System.out.println(ping);
        }
    }

**测试相关数据类型**

*  操作Key和String

//操作key string
    @Test
    public void demo1() {
        
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.242.110", 6379);        //添加
        jedis.set("name","lucy");
    
        //获取
        String name = jedis.get("name");
        System.out.println(name);
    
        //设置多个key-value
        jedis.mset("k1","v1","k2","v2");
        List<String> mget = jedis.mget("k1", "k2");
        System.out.println(mget);
    
        Set<String> keys = jedis.keys("*");
        for(String key : keys) {
        
            System.out.println(key);
        }
        jedis.close();
    }

*  操作list

//操作list
    @Test
    public void demo2() {
        
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.242.110", 6379);
        jedis.lpush("key1","lucy","mary","jack");
        List<String> values = jedis.lrange("key1", 0, -1);
        System.out.println(values);
        jedis.close();
    }

*  操作set

//操作set
    @Test
    public void demo3() {
        
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.242.110", 6379);
        jedis.sadd("names","lucy");
        jedis.sadd("names","mary");
    
        Set<String> names = jedis.smembers("names");
        System.out.println(names);
        jedis.close();
    }

*  操作hash

//操作hash
    @Test
    public void demo4() {
        
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.242.110", 6379);
        jedis.hset("users","age","20");
        String hget = jedis.hget("users", "age");
        System.out.println(hget);
        jedis.close();
    }

*  操作zset

//操作zset
    @Test
    public void demo5() {
        
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.242.110", 6379);
        jedis.zadd("china",100d,"shanghai");
    
        Set<String> china = jedis.zrange("china", 0, -1);
        System.out.println(china);
    
        jedis.close();
