Redis如何进行缓存配置(RedisCacheConfig)呢?

实现思路:
    1.引入相应的依赖
	2.编写相应的Config和Bean 

所需依赖

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

<!-- jackson依赖 -->
<dependency>
	<groupId>com.fasterxml.jackson.core</groupId>
	<artifactId>jackson-databind</artifactId>
	<version>2.13.1</version>
</dependency>

<!-- jackson依赖 -->
<dependency>
	<groupId>com.fasterxml.jackson.core</groupId>
	<artifactId>jackson-annotations</artifactId>
	<version>2.13.1</version>
</dependency>
