cannot open connection

阅读更多
我有一个SSH框架的项目,在运行一段时候后出现cannot open connection,在查找了资料了后发现是连接数不够用,所有就着手修改链接数量,在数据源的配置文件中修改
<property name="maxActive" value="1000">将最大连接改为1000
<property name="maxIdle" value="300">将最大闲置数改为300
再加上<property name="poolPreparedStatements" value="true"></property>
基本就解决问题。

要是谁看了我的这篇文章有更好的解决办法,请告知,感激不尽。
