一、单体模式

1、引入依赖

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

2、配置Redis

spring:
  redis:
    database: 1
    host: 192.168.1.191
    port: 6379
    password: imooc

3、使用

@Autowired
private RedisTemplate redisTemplate;

redisTemplate.opsForValue().set(key, value);

(String)redisTemplate.opsForValue().get(key);

redisTemplate.delete(key);
