SpringBoot整合Jedis操作redis

1.1. Jedis所需要的jar包

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>3.2.0</version>
</dependency>

1.1. 连接Redis注意事项

禁用Linux的防火墙：Linux(CentOS7)里执行命令
**systemctl stop/disable firewalld.service **
redis.conf中注释掉bind 127.0.0.1 ,然后 protected-mode no
​

1.2. Jedis常用操作

1.2.1. 创建动态的工程

1.2.1. 创建测试程序

    public static void main(String[] args) {
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.60.10", 6379);
        //测试
        String ping = jedis.ping();
        System.out.println(ping);
        jedis.close();
    }

1.3. 测试相关数据类型（其实使用Jedis和使用redis操操作没什么区别）

1.3.1. Jedis-API: Key

    //操作key String
    @Test
    public void demo1() {
        //创建Jedis对象
        Jedis jedis = new Jedis("192.168.60.10", 6379);
        //添加
        jedis.set("name", "luck");
        String name = jedis.get("name");
        System.out.println(name);
        //设置多个key-value
        jedis.mset("k1", "v1", "k2", "v2");
        List<String> mget = jedis.mget("k1", "k2");
        System.out.println(mget);


        Set<String> keys = jedis.keys("*");
        for (String key : keys
        ) {
            System.out.println(key);
        }
        jedis.close();

    }

1.3.2. Jedis-API: String

jedis.mset("str1","v1","str2","v2","str3","v3");
System.out.println(jedis.mget("str1","str2","str3"));

1.3.3. Jedis-API: List

   /**
     * 操作list
     */
    @Test
    public void demo2() {
        Jedis jedis = new Jedis("192.168.60.10", 6379);
        jedis.lpush("key1", "lucy", "marry", "jack");
        //0 ,-1表示全部都取出来
        List<String> key1 = jedis.lrange("key1", 0, -1);
        System.out.println(key1);
        jedis.close();

    }

1.3.4. Jedis-API: set

    /**
     * set
     */
    @Test
    public void demo3() {
        Jedis jedis = null;
        try {
            jedis = new Jedis("192.168.60.10", 6379);
            jedis.sadd("names", "lucy", "jack");
            Set<String> smembers = jedis.smembers("names");
            for (String name : smembers) {
                System.out.println(name);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            jedis.close();
        }


    }

1.3.5. Jedis-API: hash

    /**
     * hash操练
     */
    @Test
    public void demo4() {
        Jedis jedis = new Jedis("192.168.60.10", 6379);
        jedis.hset("users", "age", "20");
        System.out.println(jedis.hget("users", "age"));
        Map<String, String> map = new HashMap<String, String> ();
        map.put("telephone", "12346513746874");
        map.put("email", "158@163.com");
        jedis.hmset("hash2", map);
        List<String> hash2 = jedis.hmget("hash2", "telephone", "email");
        System.out.println(hash2);
        jedis.close();

    }

1.3.6. Jedis-API: zset

   /**
     * 操作zset
     *
     */
    @Test
    public void demo5() {
        Jedis jedis = new Jedis("192.168.60.10", 6379);
        jedis.zadd("china", 100, "shanghai");
        jedis.zadd("china", 200, "beijing");
        jedis.zadd("china", 300, "shengzhen");
        jedis.zadd("china", 400, "guangzhou");
        Set<String> china = jedis.zrange("china", 0, -1);
        System.out.println(china);
        jedis.close();

    }
