一、连接到redis服务
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("130.51.23.95", 12002);
System.out.println("Connection to server sucessfully");
//查看服务是否运行
System.out.println("Server is running: "+jedis.ping());
}
}
结果:
二、实例
1、字符串实例
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("130.51.23.95", 12002);
System.out.println("Connection to server sucessfully");
//查看服务是否运行
// System.out.println("Server is running: "+jedis.ping());
jedis.set("item", "001"); System.out.println(jedis.get("item"));
}
}
结果:
2、列表实例
import redis.clients.jedis.Jedis; public class RedisListJava
{
public static void main(String[] args)
{
Jedis jedis = new Jedis("130.51.23.95", 12002);
//左边插入
jedis.lpush("list-key2", "item1");
jedis.lpush("list-key2", "item2");
//右边插入
jedis.rpush("list-key2", "item3"); System.out.println(jedis.lrange("list-key2", 0, -1));
//删除
jedis.lpop("list-key2");
System.out.println(jedis.lrange("list-key2", 0, -1));
//查看redis中的所有key
System.out.println(jedis.keys("*"));
}
}
结果:
3、集合
import redis.clients.jedis.Jedis; public class RedisSetJava
{
public static void main(String[] args)
{
Jedis jedis = new Jedis("130.51.23.95", 12002);
// 插入
jedis.sadd("set-key", "item1");
jedis.sadd("set-key", "item2");
jedis.sadd("set-key", "item3"); System.out.println(jedis.smembers("set-key"));
// 查看redis中的所有key
System.out.println(jedis.keys("*"));
}
}
结果:
4、散列
import java.util.HashMap;
import java.util.Map; import redis.clients.jedis.Jedis; public class RedisHashJava
{
public static void main(String[] args)
{
Jedis jedis = new Jedis("130.51.23.95", 12002);
Map<String, String> map = new HashMap<String, String>();
map.put("name", "zhang");
map.put("age", "12");
// 插入
jedis.hmset("hash-key", map); System.out.println(jedis.hgetAll("hash-key"));
// 查看redis中的所有key
System.out.println(jedis.keys("*"));
}
}
结果:
三、删除数据
import redis.clients.jedis.Jedis; public class RedisDelJava
{
public static void main(String[] args)
{
Jedis jedis = new Jedis("130.51.23.95", 12002);
// 查看redis中的所有key
System.out.println(jedis.keys("*"));
jedis.del("list-key1");
System.out.println(jedis.keys("*"));
}
}
结果:
