篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了myBatis连接MySQL报异常:No operations allowed after connection closed.Connection was implicitly closed(示例代相关的知识,希望对你有一定的参考价值。
网站运行一个晚上,早上来上班,发现报错:
### Error querying database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.
网上查了下,由于使用了默认配置,空闲超过8小时,自动断开该连接
我使用的是mybatis的默认连接池,于是把该配的,都配置上。datasource的属性,可参考mybatis官方文档
<environment id="env_stg"> <transactionManager type="JDBC" /> <dataSource type="POOLED"> <property name="driver" value="${driver}" /> <property name="url" value="${url_stg}" /> <property name="username" value="${username}" /> <property name="password" value="${password}" /> <property name="poolMaximumActiveConnections" value="20"/> <property name="poolMaximumIdleConnections" value="5"/> <!-- MySQLNonTransientConnectionException: No operations allowed after connection closed --> <property name="poolPingQuery" value="select 1"/> <property name="poolPingEnabled" value="true"/> <!-- 对于空闲的连接一个小时检查一次 --> <property name="poolPingConnectionsNotUsedFor" value="3600000"/> </dataSource> </environment>
