@wenshao 你好，想跟你请教个问题：@wenshao 你好，想跟你请教个问题：
我在项目中使用了Druid连接池，版本：1.0.9，数据库：mysql，应用中会出现以下异常：
2014-11-06 22:36:28,537 ERROR [com.alibaba.druid.pool.DruidDataSource] - discard connection
com.mysql.jdbc.CommunicationsException: The last communications with the server was 28816 seconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.
配置了testWhileIdle=true，validationQuery=SELECT 'x'
timeBetweenEvictionRunsMillis=60000
minEvictableIdleTimeMillis=300000
我也想知道啊。。纠结。
不用线程池没发现问题，一用线程池发现了这么多问题。。网上有说手动 session.close(); ,但用的mytatis，也没有使用注解啥的，，怎么手动关闭？？
