Java uses Redis

installation

Before you start using Redis in Java, we need to make sure you have installed the Java redis redis services and drivers on your machine and normal use Java. Java installation configuration can refer to our Java development environment configuration Let's install Java redis drive:

• First you need to download the driver package, download jedis.jar , make sure to download the latest driver package.
• Including the driver package in your classpath.

Connection to redis service

import redis.clients.jedis.Jedis;
public class RedisJava {
   public static void main(String[] args) {
      //连接本地的 Redis 服务
      Jedis jedis = new Jedis("localhost");
      System.out.println("Connection to server sucessfully");
      //查看服务是否运行
      System.out.println("Server is running: "+jedis.ping());
 }
}

Java compile the above procedures to ensure that the driver package path is correct.

$javac RedisJava.java
$java RedisJava
Connection to server sucessfully
Server is running: PONG

Redis Java String Example

Redis Java String (String) instance

import redis.clients.jedis.Jedis;
public class RedisStringJava {
   public static void main(String[] args) {
      //连接本地的 Redis 服务
      Jedis jedis = new Jedis("localhost");
      System.out.println("Connection to server sucessfully");
      //设置 redis 字符串数据
      jedis.set("w3bigkey", "Redis tutorial");
     // 获取存储的数据并输出
     System.out.println("Stored string in redis:: "+ jedis.get("w3bigkey"));
 }
}

Compile the above program.

$javac RedisStringJava.java
$java RedisStringJava
Connection to server sucessfully
Stored string in redis:: Redis tutorial

Redis Java List (list) Example

import redis.clients.jedis.Jedis;
public class RedisListJava {
   public static void main(String[] args) {
      //连接本地的 Redis 服务
      Jedis jedis = new Jedis("localhost");
      System.out.println("Connection to server sucessfully");
      //存储数据到列表中
      jedis.lpush("tutorial-list", "Redis");
      jedis.lpush("tutorial-list", "Mongodb");
      jedis.lpush("tutorial-list", "Mysql");
     // 获取存储的数据并输出
     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));
     }
 }
}

Compile the above program.

$javac RedisListJava.java
$java RedisListJava
Connection to server sucessfully
Stored string in redis:: Redis
Stored string in redis:: Mongodb
Stored string in redis:: Mysql

Redis Java Keys examples

import redis.clients.jedis.Jedis;
public class RedisKeyJava {
   public static void main(String[] args) {
      //连接本地的 Redis 服务
      Jedis jedis = new Jedis("localhost");
      System.out.println("Connection to server sucessfully");
      
     // 获取数据并输出
     List<String> list = jedis.keys("*");
     for(int i=0; i<list.size(); i++) {
       System.out.println("List of stored keys:: "+list.get(i));
     }
   }
}

Compile the above program.

$javac RedisKeyJava.java
$java RedisKeyJava
Connection to server sucessfully
List of stored keys:: tutorial-name
List of stored keys:: tutorial-list
