Spring+Redis步骤
（1）、引入pom依赖
<dependency>
<groupId> org.springframework.boot</groupId>
<artifactId> spring-boot-starter-data-redis</artifactId>
</dependency>
（2）、引入RedisTemplate类，并创建RedisConfig配置类(@Configuration) ，设置redisConnectFactory，将RedisTemplate连接工具bean注入到Spring容器
（3）、引入封装RedisTemplate api的Redis工具类： RedisService/RedisUtils
（4）、引入Redis配置文件 application.properties
# Redis\u6570\u636E\u5E93\u7D22\u5F15\uFF08\u9ED8\u8BA4\u4E3A0\uFF09

RedisTemplate api
1、opsForValue 操作String，Key，Value，包含过期key，setBit位操作等
2、opsForSet 操作set
3、opsForHash 操作hash
4、opsForZset 操作SortSet
5、opsForList 操作list队列
6、opsForHash 操作hash
7、opsForZset 操作SortSet opsForList 操作list队列
