MyBatis Connection MySQL Report exception: No operations allowed after connection closed. Connection was implicitly closed

The website runs one night, comes to work in the morning, found the error:

# # # Error querying database. Cause:com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException:No operations allowed after connection Closed.

Checked online, because the default configuration is used, idle for more than 8 hours, automatically disconnect the connection

I used the default connection pool for MyBatis, so I configured the matching. DataSource properties, refer to MyBatis official documentation

        <EnvironmentID= "Env_stg">            <TransactionManagertype= "JDBC" />            <DataSourcetype= "Pooled">                < Propertyname= "Driver"value= "${driver}" />                < Propertyname= "url"value= "${url_stg}" />                < Propertyname= "username"value= "${username}" />                < Propertyname= "Password"value= "${password}" />                < Propertyname= "Poolmaximumactiveconnections"value= " the"/>                < Propertyname= "Poolmaximumidleconnections"value= "5"/>                <!--mysqlnontransientconnectionexception:no operations allowed after connection closed -                < Propertyname= "Poolpingquery"value= "Select 1"/>                < Propertyname= "poolpingenabled"value= "true"/>                <!--one-hour check for idle connections -                < Propertyname= "Poolpingconnectionsnotusedfor"value= "3600000"/>            </DataSource>        </Environment>
