SpringBoot2集成Redis

引入spring-boot-starter-data-redis

其提供了RedisTemplate来操作Redis，类似于JdbcTemplate操作数据库。

application.yml配置Redis连接信息

spring:
  redis:
    database: 0
      host: localhost
      port: 6379
      password: 123456
      timeout: 6000
      pool:
        max-active: 1000
        max-wait: -1
        max-idle: 10
        min-idle: 5

Redis配置类
