零：在test测试类下创建一个类

@SpringBootTest
public class SpringDateRedisTest {
    ...
}

一：五大操作类型

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void testRedisTemplate() {
        System.out.println(redisTemplate);
        ValueOperations valueOperations = redisTemplate.opsForValue(); //操作字符串类型数据
        HashOperations hashOperations = redisTemplate.opsForHash(); //操作哈希类型的数据
        ZSetOperations zSetOperations = redisTemplate.opsForZSet(); //操作zset
        ListOperations listOperations = redisTemplate.opsForList(); //操作list集合类型数据
        SetOperations setOperations = redisTemplate.opsForSet(); //操作set

    }

二：操作字符串的数据

    @Test
    public void testString() {
        // set get 设置键值对并获取值
        redisTemplate.opsForValue().set("city", "北京");
        String city = (String) redisTemplate.opsForValue().get("city");
        System.out.println(city);
        // setex 设置保存时间：3分钟
        redisTemplate.opsForValue().set("code", "1234", 3, TimeUnit.MINUTES);
        // setnx 如果键不存在，则设置键值对
        redisTemplate.opsForValue().setIfAbsent("lock", 1);
        redisTemplate.opsForValue().setIfAbsent("lock", 2);
    }

三：操作哈希类型的数据

    @Test
    public void testHash() {
        // hset 添加哈希字段和值
        HashOperations hashOperations = redisTemplate.opsForHash();
        hashOperations.put("100", "name", "zhangsan");
        hashOperations.put("100", "age", "18");
        // hget 获取哈希字段的值
        String name = (String) hashOperations.get("user:1", "name");
        System.out.println(name);
        // hkeys 获取哈希的所有字段
        Set keys = hashOperations.keys("100");
        System.out.println(keys);
        // hvals 获取哈希的所有值
        List values = hashOperations.values("100");
        System.out.println(values);
        // hdel 删除哈希字段
        hashOperations.delete("100", "age");
    }

四：操作list集合类型的数据

    @Test
    public void testList() {
        // lpush 将元素从左侧插入列表
        ListOperations listOperations = redisTemplate.opsForList();
        listOperations.leftPushAll("list", "a", "b", "c");
        listOperations.leftPush("list", "d");
        // lrange 获取列表指定范围的元素
        List list = listOperations.range("list", 0, -1);
        System.out.println(list);
        // lpop 从右侧弹出列表的元素a
        Object list1 = listOperations.rightPop("list");
        System.out.println(list1);
        // llen 获取列表的长度
        Long size = listOperations.size("list");
        System.out.println(size);
    }

五：操作set集合类型的数据

    @Test
    public void testSet() {
        //sadd 添加元素到集合
        SetOperations setOperations = redisTemplate.opsForSet();
        setOperations.add("set1", "a", "b", "c", "d");
        setOperations.add("set2", "a", "b", "x", "y");
        //smembers 获取集合的所有元素
        Set members = setOperations.members("set1");
        System.out.println(members);
        //scard 获取集合的长度
        Long size = setOperations.size("set1");
        System.out.println(size);
        //sinter 求交集
        Set intersect = setOperations.intersect("set1", "set2");
        System.out.println(intersect);
        //sunion 求并集
        Set union = setOperations.union("set1", "set2");
        System.out.println(union);
        //srem 删除集合中的元素
        setOperations.remove("set1", "a","b");
    }

六：操作zset类型的数据

    @Test
    public void testZset() {
        //zadd 添加元素到zset
        ZSetOperations zSetOperations = redisTemplate.opsForZSet();
        zSetOperations.add("zset", "a", 10);
        zSetOperations.add("zset", "b", 12);
        zSetOperations.add("zset", "c", 9);
        //zrange 获取指定范围的元素
        Set range = zSetOperations.range("zset", 0, -1);
        System.out.println(range);
        //zincrby 根据元素的分数进行排序，并返回元素
        zSetOperations.incrementScore("zset", "c", 10);
        //zcrem 删除元素
        zSetOperations.remove("zset", "a", "b");
    }

七：操作通用类型的数据

    @Test
    public void testCommand() {
        //keys 获取所有键
        Set keys = redisTemplate.keys("*");
        System.out.println(keys);

        //exists 判断键是否存在
        Boolean name = redisTemplate.hasKey("name");
        Boolean set1 = redisTemplate.hasKey("set1");
        System.out.println(name);
        System.out.println(set1);

        //type 获取键的类型
        for (Object key: keys){
            DataType type = redisTemplate.type(key);
            System.out.println(type.name());
        }

        //del 删除键
        redisTemplate.delete("set1");
    }
