maven简单项目的创建前面已经完成了,下面开始依赖包和配置文件的编写
好好努力每一天!!!!!!
项目结构看这里
1.首先,依赖包pom.xml

9.redis.properties --缓存配置文件
#redis setting
redis.host=127.0.0.1
redis.port=6379
#redis.password=123456
redis.maxIdle=100
redis.maxActive=300
redis.maxWait=1000
redis.testOnBorrow=true
redis.timeout=100000 fep.local.cache.capacity =10000
缓存配置的不是太成功,待后续我掌握了,再来进行修改,不设置缓存项目也是可以运行的,但是缓存是大势所趋,以后的项目,缓存大部分都会用到,很重要
redis.properties这个文件没用到,我在xml配置文件写死了,但不影响项目运行
每个章节末尾一句话勉励自己
再聪明的人,你不努力,你也仅仅只是聪明。。。。。
