遇到的问题之“动态数据源报错-recyle error java.lang.InterruptedException”

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

一、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。

二、排查问题

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【1.0.29】，然后又确认了一下官方版本是【1.1.9】，已经差了很多个版本了。

果断将版本更新至【1.1.9】

<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。

数据库连接被中断的原因有很多，有一种是初始化配置时设置的数据库连接回收时长，通过datasource.getConnontion() 取得的连接必须在removeAbandonedTimeout这么多秒内调用close(),否则就主动将其杀死，就是conn不能超过指定的租期。

详细配置可以参考这篇文章：
