Redis Java连接操作

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

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
