java项目中redis的配置好工具方法

Posted 2020-10-27 fjinlong

配置文件对redis的配置：

#REDIS_CONFIG
redis.sentinels = x.x.x.x:p,x.x.x.x:p,x.x.x.x:p

redis.sentinel.master = redis-master
redis.password = password
redispool.maxtotal = 6000
redispool.maxidle = 300
redispool.maxwaitmillis = 10000
redispool.timeout = 100



#redis单机配置
redis.pool.host=127.0.0.1
redis.pool.port=6379
#最大能够保持idel状态的对象数
redis.pool.maxIdle=100
#最大分配的对象数
redis.pool.maxTotal=6000
#等待可用连接的最大时间，单位是毫秒，默认值为-1，表示永不超时。
#如果超过等待时间，则直接抛出JedisConnectionException
redis.pool.maxWaitMillis=10000
redis.pool.timeOut=20
#多长时间检查一次连接池中空闲的连接
redis.pool.timeBetweenEvictionRunsMillis=30000
#空闲连接多长时间后会被收回
redis.pool.minEvictableIdleTimeMillis=30000
#当调用borrow Object方法时，是否进行有效性检查
#在borrow(用)一个jedis实例时，是否提前进行validate(验证)操作；
#如果为true，则得到的jedis实例均是可用的
redis.pool.testOnBorrow=true
########reids编码格式
redis.encode=utf-8
######缓存过期时间 秒  1000*60*60*24*7 七天
redis.expire=604800000
####是否开启Redis服务应用
redis.unlock=false





#redis.sentinel.host1=127.0.0.1
#redis.sentinel.port1=26379
#
#redis.sentinel.host2=127.0.0.1
#redis.sentinel.port2=26479
#
#redis.pool.maxTotal=1024
#redis.pool.maxIdle=200
#redis.pool.maxWaitMillis=1000
#redis.pool.testOnBorrow=true
#
#redis.pool.timeBetweenEvictionRunsMillis=30000
#redis.pool.minEvictableIdleTimeMillis=30000
#redis.pool.softMinEvictableIdleTimeMillis=10000
#redis.pool.numTestsPerEvictionRun=1024
#
##1000*60*60*1
#redis.pool.expire=3600000
#redis.pool.unlock=false
