Druid出现DruidDataSource - recyle error - recyle error java.lang.InterruptedException: null异常排查与解决

线上的代码之前运行的都很平稳，突然就出现了一个很奇怪的问题，看错误信息是第三方框架Druid报出来了，连接池回收连接时出现的问题。

查看一下他的源码

看了一下也没有发现所以然，然后去GitHub上的Druid官方开源处，看了一下历史问题修复，发现这个是旧版本已知的一个Bug。

https://github.com/alibaba/druid/issues/785

看了一下当前使用的Druid的版本【1.0.11】，然后又确认了一下官方最新的版本是【1.1.9】，已经差了很多个版本了。

果断将版本更新至最新

<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>druid</artifactId>
	<version>1.1.9</version>
</dependency>

翻看之前出错的那里的代码发现

更新到最新版本后，上述问题得到解决。
