Java 使用 Redis，java使用redis

Java 使用 Redis，java使用redis

安装

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Jedis

添加驱动包Jedis

连接到 redis 服务

<span >import redis.clients.jedis.Jedis;
public class RedisJava {
   public static void main(String[] args) {
      //连接本地的 Redis 服务
      Jedis jedis = new Jedis("localhost");
      System.out.println("Connection to server sucessfully");
      //查看服务是否运行
      System.out.println("Server is running: "+jedis.ping());
 }
}</span>

Redis Java String(字符串) 实例

<span >import redis.clients.jedis.Jedis;
public class RedisStringJava {
   public static void main(String[] args) {
      //连接本地的 Redis 服务
      Jedis jedis = new Jedis("localhost");
      System.out.println("Connection to server sucessfully");
      //设置 redis 字符串数据
      jedis.set("w3ckey", "Redis tutorial");
     // 获取存储的数据并输出
     System.out.println("Stored string in redis:: "+ jedis.get("w3ckey"));
 }
}

Connection to server sucessfully
Stored string in redis:: Redis tutorial</span>

Redis Java List实例

<span >import redis.clients.jedis.Jedis;
public class RedisListJava {
   public static void main(String[] args) {
      //连接本地的 Redis 服务
      Jedis jedis = new Jedis("localhost");
      System.out.println("Connection to server sucessfully");
      //存储数据到列表中
      jedis.lpush("tutorial-list", "Redis");
      jedis.lpush("tutorial-list", "Mongodb");
      jedis.lpush("tutorial-list", "Mysql");
     // 获取存储的数据并输出
     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));
     }
 }
}

Connection to server sucessfully
Stored string in redis:: Redis
Stored string in redis:: Mongodb
Stored string in redis:: Mysql</span>

Redis Java Keys 实例

<span >import redis.clients.jedis.Jedis;
public class RedisKeyJava {
   public static void main(String[] args) {
      //连接本地的 Redis 服务
      Jedis jedis = new Jedis("localhost");
      System.out.println("Connection to server sucessfully");
      
     // 获取数据并输出
     List<String> list = jedis.keys("*");
     for(int i=0; i<list.size(); i++) {
       System.out.println("List of stored keys:: "+list.get(i));
     }
   }
}

Connection to server sucessfully
List of stored keys:: tutorial-name
List of stored keys:: tutorial-list</span>
