Redis记录-JAVA连接Redis

在Java程序中使用Redis之前，需要确保在机器上安装了Redis的Java驱动程序和Java环境。可以先在将Java电脑上并配置好环境。

安装

现在，让我们看看如何设置Redis Java驱动程序。

• 下载jedis.jar - http://repo1.maven.org/maven2/redis/clients/jedis/2.1.0/jedis-2.1.0-sources.jar ，确保下载的jedis.jar是最新版本。
• 将jedis.jar包含到类路径中。

Java连接到Redis服务器

请参考以下一个简单的示例代码 -

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());
   }
}

Java

现在，编译并运行上面的程序来测试与Redis服务器的连接。可以根据需要更改路径。假设jedis.jar的当前版本在当前路径中可以使用。
执行上面代码，将生成以下结果 -

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

Java

Redis Java字符串示例

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("tutorialname"));
   }
}

Java

执行上面代码，将生成以下结果 -

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

Java

Redis 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));
      }
   }
}

Java

执行上面代码，将生成以下结果

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

Java

Redis Java键示例

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));
      }
   }
}

Java

执行上面代码，将生成以下结果 -

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