Java连接Redis

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()); 
   } 
}

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

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")); 
   } 
}

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

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 list = jedis.lrange("tutorial-list", 0 ,5); 

      for(int i = 0; i
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

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 list = jedis.keys("*"); 

      for(int i = 0; i
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
