Using Redis for Java

Installation

Before we start using Redis in Java, we need to make sure that we have the Redis service and the Java Redis driver installed and that Java is working properly on your machine. Java installation configuration can refer to our Java Development environment configuration next let's install the Java Redis driver:

• First you need to download the driver package to download Jedis.jarand make sure to download the latest driver package.
• Include the driver package in your classpath.

  <!--Https://mvnrepository.com/artifact/redis.clients/jedis -        <Dependency>            <groupId>Redis.clients</groupId>            <Artifactid>Jedis</Artifactid>            <version>2.9.0</version>        </Dependency>

Connect to the Redis service

Attention:

⊙ firewall off: UFW disable

⊙ip address settings: #bind 127.0.0.1

Class:redisjava

 PackageRedisdemo;ImportRedis.clients.jedis.Jedis; Public classRedisjava { Public Static voidMain (string[] args) {//Connect to a local Redis serviceJedis Jedis =NewJedis ("192.168.3.22"); System.out.println ("Connection to Server sucessfully"); //See if the service is runningSystem.out.println ("Server is running:" +jedis.ping ()); }}

Console:

Redis Java String (string) instance

Class:redisstringjava

 PackageRedisdemo;ImportRedis.clients.jedis.Jedis; Public classRedisstringjava { Public Static voidMain (string[] args) {//Connect to a local Redis serviceJedis Jedis =NewJedis ("192.168.3.22"); System.out.println ("Connection to Server sucessfully"); //setting up Redis string DataJedis.set ("Lime", "Redis Tutorial"); //get the stored data and outputSystem.out.println ("Stored string in Redis::" + jedis.get ("lime")); }}

Console:

Connection to server sucessfullystored string in Redis:: Redis Tutorial

Redis Java list (list) instance

Class:

 PackageRedisdemo;Importjava.util.List;ImportRedis.clients.jedis.Jedis; Public classRedislistjava { Public Static voidMain (string[] args) {//Connect to a local Redis serviceJedis Jedis =NewJedis ("192.168.3.22"); System.out.println ("Connection to Server sucessfully"); //storing data in a listJedis.lpush ("Tutorial-list", "lime"); Jedis.lpush ("Tutorial-list", "Oracle"); Jedis.lpush ("Tutorial-list", "Limeoracle"); //get the stored data and outputlist<string> list = Jedis.lrange ("Tutorial-list", 0, 5);  for(inti=0; I<list.size (); i++) {System.out.println ("Stored string in Redis::" +List.get (i)); } }}

Console:

Redis Java Keys Instance

Class:

 PackageRedisdemo;ImportJava.util.Iterator;ImportJava.util.Set;ImportRedis.clients.jedis.Jedis; Public classRediskeyjava { Public Static voidMain (string[] args) {//Connect to a local Redis serviceJedis Jedis =NewJedis ("192.168.3.22"); System.out.println ("Connection to Server sucessfully"); //get the data and outputset<string> keys = Jedis.keys ("*"); Iterator<String> it=Keys.iterator ();  while(It.hasnext ()) {String key=It.next ();           SYSTEM.OUT.PRINTLN (key); }    }}

Console:
