• Redis的Java客户端Jedis


    Jedis所需要的jar包

    Commons-pool-1.6.jar

    Jedis-2.1.0.jar

    用windows中的Eclipse连接虚拟机的Redis的注意事项

    禁用Linux的防火墙:

    临时禁用:service iptables stop

    关闭开机自启:chkconfig iptables off

    redis.conf中注释掉bind 127.0.0.1(61行) ,然后 protect-mode(80行)设置为 no。

    Jedis测试连通性

    public class Demo01 {
      public static void main(String[] args) {
        //连接本地的 Redis 服务
        Jedis jedis = new Jedis("127.0.0.1",6379);
        //查看服务是否运行,打出pong表示OK
        System.out.println("connection is OK==========>: "+jedis.ping());
      }
    }

    Jedis-API: Key

    //key
         Set<String> keys = jedis.keys("*");
         for (Iterator iterator = keys.iterator(); iterator.hasNext();) {
           String key = (String) iterator.next();
           System.out.println(key);
         }
         System.out.println("jedis.exists====>"+jedis.exists("k2"));
         System.out.println(jedis.ttl("k1"));
          

    Jedis-API: String

         System.out.println(jedis.get("k1"));
         jedis.set("k4","k4_Redis");
         System.out.println("----------------------------------------");
         jedis.mset("str1","v1","str2","v2","str3","v3");
         System.out.println(jedis.mget("str1","str2","str3"));

    Jedis-API: List

        List<String> list = jedis.lrange("mylist",0,-1);
         for (String element : list) {
           System.out.println(element);
         }

    Jedis-API: set

         jedis.sadd("orders","jd001");
         jedis.sadd("orders","jd002");
         jedis.sadd("orders","jd003");
         Set<String> set1 = jedis.smembers("orders");
         for (Iterator iterator = set1.iterator(); iterator.hasNext();) {
           String string = (String) iterator.next();
           System.out.println(string);
         }
         jedis.srem("orders","jd002");

    Jedis-API: hash

         jedis.hset("hash1","userName","lisi");
         System.out.println(jedis.hget("hash1","userName"));
         Map<String,String> map = new HashMap<String,String>();
         map.put("telphone","13810169999");
         map.put("address","atguigu");
         map.put("email","abc@163.com");
         jedis.hmset("hash2",map);
         List<String> result = jedis.hmget("hash2", "telphone","email");
         for (String element : result) {
           System.out.println(element);
         }

    Jedis-API: zset

         jedis.zadd("zset01",60d,"v1");
         jedis.zadd("zset01",70d,"v2");
         jedis.zadd("zset01",80d,"v3");
         jedis.zadd("zset01",90d,"v4");
         Set<String> s1 = jedis.zrange("zset01",0,-1);
         for (Iterator iterator = s1.iterator(); iterator.hasNext();) {
           String string = (String) iterator.next();
           System.out.println(string);
         }
