import redis.clients.jedis.Jedis;
public class TestPing {
    public static void main(String[] args) {
        //new Jedis对象
        Jedis jedis =  new Jedis("服务器ip",6379);
        //Jedis所有命令都在对象里
        System.out.println(jedis.ping());
    }
}
执行成功,输出pong
注意:想要连接远程服务器的redis,必须注意以下几点
String List Set Hash Zset
import com.alibaba.fastjson.JSONObject;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.Transaction;
public class TestTX {
    public static void main(String[] args) {
        Jedis jedis =  new Jedis("203.195.154.132",6379);
        jedis.flushDB();
        Transaction multi = jedis.multi();
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("hello","world");
        jsonObject.put("name","dengwei");
        String s = jsonObject.toJSONString();
        try {
            multi.set("user1",s);
            multi.set("user2",s);
            multi.exec();
        }catch (Exception e) {
            multi.discard();
            e.printStackTrace();
        }finally {
            System.out.println(jedis.get("user1"));
            System.out.println(jedis.get("user2"));
            jedis.close();
        }
    }
}
