配置文件

redis.properties

#访问地址redis.host=123.57.36.122#访问端口redis.port=6379#注意，如果没有password，此处不设置值，但这一项要保留redis.password=sp6161266#最大空闲数，数据库连接的最大空闲时间。超过空闲时间，数据库连接将被标记为不可用，然后被释放。设为0表示无限制。redis.maxIdle=300#连接池的最大数据库连接数。设为0表示无限制redis.maxActive=600#最大建立连接等待时间。如果超过此时间将接到异常。设为-1表示无限制。redis.maxWait=1000#在borrow一个jedis实例时，是否提前进行alidate操作；如果为true，则得到的jedis实例均是可用的；redis.testOnBorrow=true
