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 RedisStringJava
Connection to server sucessfully
Stored 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 RedisListJava
Connection to server sucessfully
Stored string in redis:: Redis
Stored string in redis:: Mongodb
Stored 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 RedisKeyJava
Connection to server sucessfully
List of stored keys:: tutorial-name
List of stored keys:: tutorial-list
