Redis series--6, Redis Java connection operation

Installation

To use Redis in a Java program, you need to make sure that there are redis Java drivers and Java settings on the machine. You can check out the Java tutorial-Learn how to install Java on your machine. Now, let's look at how to set up a Redis Java driver.

• Need to download Jedis.jar. Be sure to download the latest version of it.

• You need to include Jedis.jar into your classpath.

Connect to a Redis server

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 ());}}

Now, let's compile and run the program above to test the connection to the Redis server. You can change the path according to the actual situation. This assumes that the current version of Jedis.jar is available in the current path

$javac Redisjava.java$java redisjavaconnection to server sucessfullyserver is Running:pong

Redis and Java string instances

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"));  }}

Now, let's compile and run the above program.

$javac Redisstringjava.java$java redisstringjavaconnection to server sucessfullystored string in Redis:: Redis Tutorial

Examples of Redis and Java column representations

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));      } }}

$javac Redislistjava.java$java redislistjavaconnection to server sucessfullystored string in Redis:: redisstored string I N Redis:: mongodbstored string in Redis:: Mysql

Key instances for Redis and Java

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));      }    }}

Now, let's compile and run the above program.

$javac Rediskeyjava.java$java rediskeyjavaconnection to server sucessfullylist of stored keys:: Tutorial-namelist of Stor Ed Keys:: Tutorial-list
