- 在 pom.xml 文件中添加 Redis 的依賴：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
- 在 application.yml 文件中添加 Redis 的配置：
spring:
redis:
host: 127.0.0.1
port: 6379
database: 1
pool:
max-idle: 8
min-idle: 0
max-active: 8
max-wait: -1
- 在 Application.java 類中添加 @EnableCaching 注解，啟用緩存：
@EnableCaching
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
- 在 Repository 或 Service 類的方法中添加緩存相關(guān)的注解：

import org.springframework.cache.annotation.CacheEvict;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.cache.annotation.Caching;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
