java 使用redis——迹忆客-ag捕鱼王app官网

开始在 java 中使用 redis 前， 我们需要确保已经安装了 redis 服务及 java redis 驱动，且你的机器上能正常使用 java。

安装

首先，安装 redis 的 java 驱动。

• 首先你需要下载驱动包，确保下载最新驱动包。
• 在你的 classpath 中包含该驱动包。

示例

连接到 redis 服务

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()); 
   } 
} 

编译并运行程序。可以根据需要修改你的路径。我们假设 jedis.jar 在当前路径中。

$javac redisjava.java 
$java redisjava 
connection to server sucessfully 
server is running: pong

redis java string 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("jiyikey", "www.jiyik.com"); 
      // get the stored data and print it 
      system.out.println("stored string in redis:: "  jedis.get("site-name")); 
   } 
}

编译和运行上面的程序

$javac redisstringjava.java 
$java redisstringjava 
connection to server sucessfully 
stored string in redis:: www.jiyik.com

redis java list 实例

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("site-list", "jiyik"); 
      jedis.lpush("site-list", "baidu"); 
      jedis.lpush("site-list", "zhihu"); 
      // get the stored data and print it 
      list list = jedis.lrange("site-list", 0 ,5); 
      for(int i = 0; i

$javac redislistjava.java 
$java redislistjava 
connection to server sucessfully 
stored string in redis:: jiyik 
stored string in redis:: baidu 
stored string in redis:: zhihu

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 list = jedis.keys("*"); 
      for(int i = 0; i

$javac rediskeyjava.java 
$java rediskeyjava 
connection to server sucessfully 
list of stored keys:: jiyikey 
list of stored keys:: site-list
