解决使用redisTemplate高并发下连接池满的问题

 #redis setting redis.host=localhost redis.port=6379 redis.password= redis.maxIdle=200 redis.minIdle=0 redis.maxActive=50 redis.maxWait=10000 redis.testOnBorrow=true redis.timeout=100000 #定义需要使用的db //#sessionCode DB sessionCodeDb = 0 //#车辆基本信息 DB bicycleInfoDb = 15 //#当前位置信息 DB currentLocationDb = 14 //#锁车/解锁 DB lockDb = 13 //#根据车牌获取电子车牌 DB ebikeNoDb = 12 //#根据电子车牌获取车牌 DB bikeNoDb = 11
