要在Java程序中使用使用操作Redis，需要確保有Redis的Java驅動程序和Java設置在機器上。現在，讓我們來看看如何設置Redis的Java驅動程序。
- 需要下載jedis.jar。請一定要下載它的最新版本。
- 需要包括jedis.jar到你的類路徑中。

import redis.clients.jedis.Jedis;public class RedisJava { public static void main(String[] args) { //Connecting to Redis server on localhost Jedis jedis = new Jedis("localhost"); System.out.println("Connection to server sucessfully"); //check whether server is running or not System.out.println("Server is running: "+jedis.ping()); }} |
現在，讓我們來編譯和運行上面的程序來測試連接Redis服務器。你可以根據實際情況改變路徑。這里假設jedis.jar的當前版本在當前路徑中可用
