先搭建好redis环境
需要的jar如下:
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/cache_test
jdbc.username=root
jdbc.password=
redis.host=127.0.0.1
redis.port=6379
redis.maxIdle=2000
redis.maxActive=60000
redis.maxWait=1000
redis.testOnBorrow=true
redis.timeout=100000
defaultCacheExpireTime=60
