1. Demo - 总

public class RedisMain {
    public static void main(String[] args) throws InterruptedException {
        // 0. 启动redis # redis-server /usr/local/etc/redis.conf
        // 1. 获取连接
        //Jedis jedis = new Jedis("localhost", 6379); // = cmd redis-cli
        // 从连接池获取jedis连接对象
        Jedis jedis = JedisUtil.getJedis();
        // 如果设置了密码执行此步骤
        jedis.auth("123456Aa"); // = command    auth 123456Aa
        // testString(jedis);
        // testHash(jedis);
        testList(jedis);
        System.out.println("=======================");
        testSet(jedis);
        System.out.println("=======================");
        testZset(jedis);
        Set<String> keys = jedis.keys("*");
        if (keys != null) {
            keys.forEach(jedis::del);
        }
        // 正常关闭 或 将jedis连接归还到连接池中
        jedis.close();
    }
}

2. String

    // string : set / get / del
    private static void testString(Jedis jedis) throws InterruptedException {
        // 写操作
        jedis.set("username", "test");
        jedis.setex("username-expire", 2, "test-expire");
        // 读操作
        String username = jedis.get("username");
        String usernameExpire = jedis.get("username-expire");
        System.out.println(username);
        System.out.println(usernameExpire);
        Thread.sleep(3000);
        username = jedis.get("username");
        usernameExpire = jedis.get("username-expire");
        System.out.println(username);
        System.out.println(usernameExpire);
        jedis.del("username");
        username = jedis.get("username");
        System.out.println(username);
    }

3. Hash

    // hash : hset / hget / hgetall / hdel
    private static void testHash(Jedis jedis) {
        Map<String, String> map = new HashMap<>();
        map.put("key1", "value1");
        jedis.hset("mymap", map);
        System.out.println(jedis.hget("mymap", "key1"));
        System.out.println(jedis.hgetAll("mymap"));
        jedis.hdel("mymap", "key1");
        System.out.println(jedis.hgetAll("mymap")); // nothing
    }

4. List

    // list : lpush / rpush / lrange / lpop / rpop
    public static void testList(Jedis jedis) {
        jedis.lpush("mylist", "first-left", "second-left");
        jedis.rpush("mylist", "first-right", "second-right");
        System.out.println(jedis.lrange("mylist", 0, -1));
        System.out.println(jedis.lpop("mylist"));
        System.out.println(jedis.rpop("mylist"));
        System.out.println(jedis.lrange("mylist", 0, -1));
    }

5. Set

    // set : sadd / smembers / srem
    private static void testSet(Jedis jedis) {
        jedis.sadd("myset", "a", "b", "c");
        System.out.println(jedis.smembers("myset"));
        jedis.srem("myset", "c");
        System.out.println(jedis.smembers("myset"));
    }

6. Zset

    // zset : zadd / zrange / zrem
    private static void testZset(Jedis jedis) {
        jedis.zadd("my-sort-set", 99, "c");
        jedis.zadd("my-sort-set", 97, "a");
        jedis.zadd("my-sort-set", 98, "b");
        System.out.println(jedis.zrange("my-sort-set", 0, -1));
        jedis.zrem("my-sort-set", "a");
        System.out.println(jedis.zrange("my-sort-set", 0, -1));
    }

7. Jedis连接池

// 简单流程，异常场景请自行覆盖～
public class JedisUtil {
    private static final JedisPool jedisPool;

    static {
        // 读取配置文件
        InputStream is = JedisUtil.class.getClassLoader().getResourceAsStream("redis/redis.properties");
        Properties pro = new Properties();
        try {
            pro.load(is);
        } catch (IOException e) {
            e.printStackTrace();
        }
        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxIdle(Integer.parseInt(pro.getProperty("maxIdle")));
        config.setMaxTotal(Integer.parseInt(pro.getProperty("maxTotal")));
        jedisPool = new JedisPool(config, pro.getProperty("host"), Integer.parseInt(pro.getProperty("port")));
    }

    public static Jedis getJedis() {
        return jedisPool.getResource();
    }
}
