Using Java to operate Redis

To use Java to operate Redis, you first need to import Redis's Java client dependency package. The commonly used Redis Java clients include Jedis and Lettuce. Let's take Jedis as an example to introduce how to use Java to operate Redis. 1. Add Maven dependency: <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>3.6.0</version> </dependency> 2. Connect Redis in Java code: import redis.clients.jedis.Jedis; public class RedisExample { public static void main(String[] args) { //Connect Redis Jedis jedis = new Jedis("localhost", 6379); //Execute Redis command jedis.set("key", "value"); //Close Connection jedis.close(); } } 3. Data insertion, modification, and query: import redis.clients.jedis.Jedis; public class RedisExample { public static void main(String[] args) { //Connect Redis Jedis jedis = new Jedis("localhost", 6379); //Insert Data jedis.set("name", "John"); jedis.set("age", "25"); //Modify data jedis.set("age", "26"); //Query data String name = jedis.get("name"); String age = jedis.get("age"); System.out.println("Name: " + name); System.out.println("Age: " + age); //Close Connection jedis.close(); } } 4. Data deletion: import redis.clients.jedis.Jedis; public class RedisExample { public static void main(String[] args) { //Connect Redis Jedis jedis = new Jedis("localhost", 6379); //Delete data jedis.del("name"); //Close Connection jedis.close(); } } The above code example shows how to use Java to operate Redis, including connecting to Redis, inserting, modifying, querying, and deleting data. In practical use, according to specific needs, more Redis commands can be called to achieve more complex operations.
