这个算是工作笔记吧,因为是我的实际工作内容
spring-data-redis api地址 http://docs.spring.io/spring-data/redis/docs/current/api/

redis.properties的文件内容如下,maven管理的话,可以分别设置开发环境,测试环境,预发布环境,生产环境等
- redis.pool.maxActive=1024
- redis.pool.maxIdle=200
- redis.pool.maxWait=1000
- redis.pool.testOnBorrow=true
- redis.pool.testOnReturn=true
-
- #database
- redis.ip=192.168.0.246
- redis.port=6378
- redis.password=
- redis.timeout=5000
- redis.database=1
