这是我的连接池配置
#连接池的配置信息
initialSize: 10
minIdle: 10
maxActive: 30
maxWait: 60000

testOnReturn: false
poolPreparedStatements: false
maxPoolPreparedStatementPerConnectionSize: 20

connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

下面是项目启动 首次访问数据库

  大家注意看时间，创建10个连接要20S，网络没问题的，数据库也没问题

第二点 隔一段时间不访问，再次去访问后台，他又重新创建数据连接，代码如下

• (3368512 ms) - [DEBUG] 2020-09-18 12:00:09,236 org.mybatis.spring.SqlSessionUtils - Creating a new SqlSession
• (3368512 ms) - [DEBUG] 2020-09-18 12:00:09,236 org.mybatis.spring.SqlSessionUtils - SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@5ee0c04d] was not registered for synchronization because synchronization is not active
• (3368512 ms) - [DEBUG] 2020-09-18 12:00:09,236 druid.sql.Connection - {conn-10018} pool-connect

这样正常么？使用了连接池不应该是超时的连接报废，然后保持10个待使用连接么
