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
