关于“druid close connection error”的问题,这通常涉及到数据库连接池Druid在尝试关闭一个数据库连接时遇到的错误。以下是对这个问题的详细分析和解决方案: 1. 确认错误上下文 首先,确认错误确实是关于Druid数据库连接池的关闭连接错误。这个错误可能发生在多种情况下,比如连接超时、网络问题、数据库配置不当等。 2....

其次这里的close是拿着驱动那个连接对象进行close,正常情况下一个连接对象会被druid封装成DruidPooledConnection对象,内部持有的conn就是真正的驱动Connection对象,上图中的关闭连接就是获取的该对象进行close,如果使用包装类DruidPooledConnection进行close,则代表回收连接对象(recycle,参考主流程5)。
