一、Spring整合Redis

首先我们要开启Redis服务

进入Redis的安装目录里

输入命令：./src/redis-service redis-conf

开始链接：./src/redis-cli -h 虚拟机IP -p 6379 -a 密码

整合步骤：

1、导入相关pom依赖；

2、修改pom依赖include中的jdbc.properties，把jdbc改为 * 号；

3、导入spring-redis.xml文件；

4、导入redis.properties文件；

5、在applicationContext.xml文件中添加外部多文件方式；

6、建立redis文件夹，导入指定生成规则文件CacheKeyGenerator.java；

【要在IDEA中下载Lombok插件】
