1.Redis 下载

Windows 版本下载：https://github.com/dmajkic/redis/downloads

2.解压到

C:\redis-2.4.5-win32-win64

3.启动Redis server

4. 启动Redis 客户端

redis-cli.exe -h 127.0.0.1 -p 6379

5. 测试Redis

二、Java中使用redis

public class RedisJava {
	public static void main(String[] args) {
		Jedis jedis = new Jedis("localhost");
		//jedis.auth("123456");
		System.out.println("Connection success");
		System.out.println("Serving is running: " + jedis.ping());
		//testString(jedis);
		//testMap(jedis);
		String key = "author";
		jedis.sadd(key, "zhangsan");
		jedis.sadd(key, "lisi");
		jedis.sadd(key, "wangwu");
		jedis.sadd(key, "zhaoliu");
		jedis.srem(key, "zhaoliu"); // 移除zhaoliu
		jedis.expire(key, 2);
		System.out.println(jedis.smembers(key));//输出set中所有数据
		try {
			Thread.sleep(3000);
		} catch (InterruptedException e) {
		}
		System.out.println("查看author的剩余生存时间：" + jedis.ttl(key));
		// 移除某个key的生存时间
		System.out.println("移除author的生存时间：" + jedis.persist(key));
		System.out.println("查看author的剩余生存时间：" + jedis.ttl(key));
		System.out.println(jedis.smembers(key));//输出set中所有数据
	}
	private static void testMap(Jedis jedis) {
		String key = "student";
		Map<String, String> map = new HashMap<String,String>();
		map.put("name", "zhangsan");
		map.put("age", "100");
		map.put("sex", "male");
		jedis.hmset(key, map);
		List<String> stuList = jedis.hmget(key, "name","age","sex");
		System.out.println(stuList);
		System.out.println("student中的所有key： " + jedis.hkeys(key)); 
		System.out.println("student中的所有value: " + jedis.hvals(key)); 
		System.out.println("-----------------------------------------"); 
		Iterator<String> iterator = jedis.hkeys(key).iterator();
		while (iterator.hasNext()) {
			String itemKey = iterator.next();
			String itemValue = jedis.hget(key, itemKey);
			System.out.println("itemKey: " + itemKey + " itemValue： " + itemValue);
		}
		System.out.println("-----------------------------------------"); 
		jedis.hdel(key, "sex");
		System.out.println("student 是否存在： " + jedis.exists(key)); 
		System.out.println("student 长度: " + jedis.hlen("student"));//sex 已经删除,所以长度为2
		System.out.println(jedis.hmget(key, "name","sex")); //sex 已经删除，所以为null
	}
	private static void testString(Jedis jedis) {
		jedis.set("address", "hangzhou ");
		System.out.println("address: " + jedis.get("address"));
		jedis.append("address", "west lake");//拼接
		System.out.println("address: " + jedis.get("address"));
		jedis.del("address");
		System.out.println("address: " + jedis.get("address"));
		jedis.mset("name","zhangsan","sex","male","age","100");
		jedis.incr("age");
		System.out.println(jedis.get("name") + " " + jedis.get("age") + " " + jedis.get("sex"));
	}
}
