要在Java程序中使用使用操作Redis，需要确保有Redis的Java驱动程序和Java设置在机器上。现在，让我们来看看如何设置Redis的Java驱动程序。
连接到Redis服务器
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()); }}现在，让我们来编译和运行上面的程序来测试连接Redis服务器。你可以根据实际情况改变路径。这里假设jedis.jar的当前版本在当前路径中可用
$javac RedisJava.java$java RedisJavaConnection to server sucessfullyServer is running: PONG
Redis和Java字符串实例
import redis.clients.jedis.Jedis;public class RedisStringJava { public static void main(String[] args) { //Connecting to Redis server on localhost Jedis jedis = new Jedis("localhost"); System.out.println("Connection to server sucessfully"); //set the data in redis string jedis.set("tutorial-name", "Redis tutorial"); // Get the stored data and print it System.out.println("Stored string in redis:: "+ jedis.get("tutorial-name")); }}现在，让我们编译并运行上述程序。
$javac RedisStringJava.java$java RedisStringJavaConnection to server sucessfullyStored string in redis:: Redis tutorial
Redis和Java列表示例
import redis.clients.jedis.Jedis;public class RedisListJava { public static void main(String[] args) { //Connecting to Redis server on localhost Jedis jedis = new Jedis("localhost"); System.out.println("Connection to server sucessfully"); //store data in redis list jedis.lpush("tutorial-list", "Redis"); jedis.lpush("tutorial-list", "Mongodb"); jedis.lpush("tutorial-list", "Mysql"); // Get the stored data and print it List<String> list = jedis.lrange("tutorial-list", 0 ,5); for(int i=0; i<list.size(); i++) { System.out.println("Stored string in redis:: "+list.get(i)); } }}现在，让我们编译并运行上述程序。
$javac RedisListJava.java$java RedisListJavaConnection to server sucessfullyStored string in redis:: RedisStored string in redis:: MongodbStored string in redis:: Mysql
Redis和Java的键实例
import redis.clients.jedis.Jedis;public class RedisKeyJava { public static void main(String[] args) { //Connecting to Redis server on localhost Jedis jedis = new Jedis("localhost"); System.out.println("Connection to server sucessfully"); //store data in redis list // Get the stored data and print it List<String> list = jedis.keys("*"); for(int i=0; i<list.size(); i++) { System.out.println("List of stored keys:: "+list.get(i)); } }}现在，让我们编译并运行上述程序。
$javac RedisKeyJava.java$java RedisKeyJavaConnection to server sucessfullyList of stored keys:: tutorial-nameList of stored keys:: tutorial-list
