RedisTemplate is commonly used to operate Redis

Five data structure operations are defined in RedisTemplate

redisTemplate.opsForValue();//操作字符串
redisTemplate.opsForHash();//操作hash
redisTemplate.opsForList();//操作list
redisTemplate.opsForSet();//操作set
redisTemplate.opsForZSet();//操作有序set

RedisTemplate's operations on these five data structures are similar, the following takes the operation string as an example:
1. Add Redis dependency

<!-- redis依赖 -->
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2. Inject RedisTemplate first

@Autowired
private RedisTemplate<String,String> redis;

3. Set the key and value values: the first parameter represents Key, and the second parameter represents Value

redis.opsForValue().set("Token", "Kzl6N3RJeFBmQlNQamlVNW4zUThoQT09");//设置值

4. Set the timeout period. The first parameter indicates the Key name, the second parameter indicates the time, and the third parameter indicates milliseconds, minutes, days, etc.

redis.expire("Token",3,TimeUnit.MINUTES);//设置过期时间3分钟

5. Get the key value: the parameter represents the key name

redis.opsForValue().get("Token");
