设置连接池。重新连接到数据库

标签: mysql tomee connection-pool

tomee 8中的连接池出现问题。工作约8个小时后,与数据库的连接断开。如何配置重新连接到数据库。

我考虑了validationQuery testOnBorrow。也有选项removeAbandoned removeAbandonedTimeout,但他们写道这是不可取的。 defaultAutoCommit并不真正理解为什么,但是据我所知,文档是关于重新连接的。

server.xml

<Resource name="jdbc/chessman_work" 
              auth="Container" 

              type="javax.sql.DataSource" 
              driverClassName="com.mysql.cj.jdbc.Driver" 

              url="jdbc:mysql://localhost:3306/chessman_work?zeroDateTimeBehavior=CONVERT_TO_NULL&amp;serverTimezone=UTC&amp;allowPublicKeyRetrieval=true&amp;useSSL=false&amp;characterEncoding=utf8&amp;useUnicode=true" 

              username="*******" 
              password="***********"

              maxActive="30"
              maxIdle="5"

              factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"/>

是的,将验证查询和testWhildle设置为某个时间间隔,此问题应消失。如果您不太关心性能,甚至可以使用testOnBorrow = true。
