java - 如果连接无效，BoneCP 将不会返回或抛出

Question

使用 BoneCp 0.7.1

我设置了我的应用程序并且一切正常，但随后数据库离线了。

在下一个应用程序请求中，getConnection() 开始抛出内部异常，重试机制启动，但 getConnection() 从未返回，线程挂起。

下面的异常被一遍又一遍地抛出，但你会期望 getConnection() 返回 NULL 或抛出一个 SQLException 至少这样你就可以处理它。

这看起来很相似:http://jolbox.com/forum/viewtopic.php?t=339&p=1390但是我的问题是在建立连接后出现的。

还看到了这个... BoneCP doesn't recover from broken connection我会试试 8.0-rc1

尝试过 8.0-rc2 相同的问题 getConnection() 不会返回。

Answer 1

老问题，但我可以建议尝试 HikariCP以提高可恢复性。
