通过java操作redis

前提是redis服务器已启动
package redis;

import redis.clients.jedis.Jedis;


import java.util.HashMap;

public class Redis002 {
    public static void main(String[] args) {
        Jedis jedis = new Jedis("192.168.220.129", 6380);
//获取所有的key
        System.out.println(jedis.keys("*"));
//通过hset赋值
        jedis.hset("custom", "name", "zhangsan");
//通过hget获取值
        System.out.println(jedis.hget("custom", "name"));
        HashMap<String, String> hm = new HashMap();
        hm.put("name", "乔村小学");
        hm.put("year", "2013");
//通过hmset赋值
        jedis.hmset("school", hm);
//通过hmget获取值
        System.out.println(jedis.hmget("school", "name", "year"));
//通过hkeys来获取school里的所有key
        System.out.println(jedis.hkeys("school"));
//通过hvals来获取school里的所有vals
        System.out.println(jedis.hvals("school"));
//通过hexists来判断school里的key为name是否存在
        System.out.println(jedis.hexists("school", "name"));
//通过hgetAll来获取school里的所有键值对
        System.out.println(jedis.hgetAll("school"));
//通过hdel来删除school里的key为name的键值对
        jedis.hdel("school", "name");
        System.out.println(jedis.hgetAll("school"));
//通过hincrBy来增加key为year的value值
        jedis.hincrBy("school", "year", 20);
        System.out.println(jedis.hget("school", "year"));
        jedis.hincrBy("school", "year", 30);

//通过hlen来获取school里的键值对个数
        System.out.println(jedis.hlen("school"));
