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();
}
}
}
